function cropImage($nw, $nh, $source, $stype, $dest) {

$size = getimagesize($source); // get size

$simg = imagecreatefromjpeg($source);

break;

case png:

$wm = $w/$nw;

$hm = $h/$nh;

$h_height = $nh/2;

$w_height = $nw/2;

if($w> $h) {

$adjusted_width = $w / $hm;

$half_width = $adjusted_width / 2;

$int_width = $half_width - $w_height;

Using the static Statement to Remember the Value of a Variable Between Function Calls

If you declare a variable within a function in conjunction with the static statement, the variable remains local to the function, and the function "remembers" the value of the variable from execution to execution

<?php
function numberedHeading($txt) {
static $num_of_calls = 0;
$num_of_calls++;
echo "<h1>".$num_of_calls." ". $txt."</h1>"; }
numberedHeading("Mobile Phones");
echo "<p>We build a fine range of mobile phones.</p>";
numberedHeading("Camera");
echo "<p>Also Digital Cameras..</p>";
?>

The numberedHeading() function has become entirely self-contained. When we declare the $num_of_calls variable on line 3, we assign an initial value to it. This assignment is made when the function is first called on line 7. This initial assignment is ignored when the function is called a second time on line 9. Instead, the code remembers the previous value of $num_of_calls. We can now paste the numberedHeading() function into other scripts without worrying about global variables.

Saving State Between Function Calls with the static Statement

Local variables within functions have a short but happy life they come into being when the function is called and die when execution is finished, as they should. Occasionally, however, you may want to give a function a rudimentary memory.

Lets assume that we want a function to keep track of the number of times it has been called so that numbered headings can be created by a script. We could, of course, use the global statement to do this, as shown in Listing below:

<?php

$num_of_calls = 0;

function numberedHeading($txt) {

global $num_of_calls;

$num_of_calls++;

echo "<h1>".$num_of_calls." ".$txt."</h1>";

}

numberedHeading("Mobile Phones");

echo "<p>We build a fine range of mobile phones.</p>";

numberedHeading("Camera");

echo "<p>Also Digital Cameras.</p>";

?>

Thumbnail and Watermark On The Fly

Sometimes we may want to create thumbnails and/or watermark on-the-fly for images on our web sites instead of creating offline by using some tools or image editors. We want to generate it automatically from our php scripts. Thus, we can use thumbnail class made by Emilio Rodriguez  and we can download it from phpclass.org or from here (including an example file 7kb).

/**

*This is a class that can process an image on the fly by either generate a thumbnail, apply an watermark to the image, or resize it.

*

* The processed image can either be displayed in a page, saved to a file, or returned to a variable.

* It requires the PHP with support for GD library extension in either version 1 or 2. If the GD library version 2 is available it the class can manipulate the images in true color, thus providing better quality of the results of resized images.

* Features description:

* - Thumbnail: normal thumbnail generation

* - Watermark: Text or image in PNG format. Suport multiples positions.

* - Auto-fitting: adjust the dimensions so that the resized image aspect is not distorted

* - Scaling: enlarge and shrink the image

* - Format: both JPEG and PNG are supported, but the watermark image can only be in PNG format as it needs to be transparent

* - Autodetect the GD library version supported by PHP

* - Calculate quality factor for a specific file size in JPEG format.

* - Suport bicubic resample algorithm

* - Tested: PHP 4 valid

FPDF PHP Script To Create PDF On The Fly

FPDF is a PHP class which allows to generate PDF files with pure PHP, that is to say without using the PDFlib library. F from FPDF stands for Free: you may use it for any kind of usage and modify it to suit your needs.

FPDF has other advantages: high level functions. Here is a list of its main features:

•     Choice of measure unit, page format and margins
•     Page header and footer management
•     Automatic page break
•     Automatic line break and text justification
•     Image support (JPEG, PNG and GIF)
•     Colors
•     Links
•     TrueType, Type1 and encoding support
•     Page compression

FPDF PHP Script requires no extension (except zlib to activate compression and GD for GIF support). It works with PHP 4 and PHP 5 (the latest version requires at least PHP 4.3.10).

 An Example...

Lets start with the classic example:

<?php
require(fpdf.php);

$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont(Arial,B,16);
$pdf->Cell(40,10,Hello World!);
$pdf->Output();
?>

After including the library file, we create an FPDF object. The FPDF() constructor is used here with the default values: pages are in A4 portrait and the unit of measure is millimeter. It could have been specified explicitly with:

$pdf = new FPDF(P,mm,A4);

Its possible to use landscape (L), other page sizes (such as Letter and Legal) and units (pt, cm, in).

Theres no page at the moment, so we have to add one with AddPage(). The origin is at the upper-left corner and the current position is by default set at 1 cm from the borders; the margins can be changed with SetMargins().

Before we can print text, its mandatory to select a font with SetFont(), otherwise the document would be invalid. We choose Arial bold 16:

$pdf->SetFont(Arial,B,16);

We could have specified italics with I, underlined with U or a regular font with an empty string (or any combination). Note that the font size is given in points, not millimeters (or another user unit); its the only exception. The other standard fonts are Times, Courier, Symbol and ZapfDingbats.

We can now print a cell with Cell(). A cell is a rectangular area, possibly framed, which contains a line of text. It is output at the current position. We specify its dimensions, its text (centered or aligned), if borders should be drawn, and where the current position moves after it (to the right, below or to the beginning of the next line). To add a frame, we would do this:

$pdf->Cell(40,10,Hello World !,1);

 To add a new cell next to it with centered text and go to the next line, we would do:

$pdf->Cell(60,10,Powered by FPDF.,0,1,C);

Remark: the line break can also be done with Ln(). This method additionnaly allows to specify the height of the break.

Finally, the document is closed and sent to the browser with Output(). We could have saved it to a file by passing the desired file name.

Caution: in case when the PDF is sent to the browser, nothing else must be output by the script, neither before nor after (no HTML, not even a space or a carriage return). If you send something before, you will get the error message: "Some data has already been output, cant send PDF file". If you send something after, the document might not display.

Accessing Variables with the global Statement

From within one function, you cannot (by default) access a variable defined in another function or elsewhere in the script. Within a function, if you attempt to use a variable with the same name, you will only set or access a local variable. Lets put this to the test :

<?php

$life = 42;

function meaningOfLife() {

echo "The meaning of life is ".$life;

}

meaningOfLife();

?>

Put these lines into a text file called scopetest2.php and place this file in your web server document root. When you access this script through your web browser, it should look like:

As you might expect, the meaningOfLife() function does not have access to the $life variable in line 2; $life is empty when the function attempts to print it. On the whole, this is a good thing because it saves us from potential clashes between identically named variables, and a function can always demand an argument if it needs information about the outside world. Occasionally, you may want to access an important variable from within a function without passing it in as an argument. This is where the global statement comes into play. Use global to restore order to the universe.

<?php

$life=42;

function meaningOfLife() {

global $life;

echo "The meaning of life is ".$life;

}

meaningOfLife();

?>

Put these lines into a text file called scopetest3.php and place this file in your web server document root. When you access this script through your web browser, it should look like:

By placing the global statement in front of the $life variable when we declare it in the meaningOfLife() function (line 4), it now refers to the $life variable declared outside the function (line 2).

You will need to use the global statement within every function that needs to access a particular named global variable. Be careful, though; if you manipulate the contents of the variable within the function, the value of the variable will be changed for the script as a whole.

You can declare more than one variable at a time with the global statement by simply separating each of the variables you want to access with commas:

global $var1, $var2, $var3;

Watch Out!

Usually, an argument is a copy of whatever value is passed by the calling code; changing it in a function has no effect beyond the function block. Changing a global variable within a function, on the other hand, changes the original and not a copy. Use the global statement carefully.

The continue statement

The continue statement ends the execution of th current iteration but doesnt end the loop as a whole. Instead, the next iteration begins immediately. Using the previous example as in the break statement, replacing the break statement with the continue statement, we can get rid of a divide-by-zero error without ending the loop completely. See the example below:

<?php
$i = -4;
for ($i ; $i <= 10; $i++ ) {
if ( $i == 0 )
continue;
$temp = 1000/$i;
print "1000 divided by $i is... $temp<br>";
}
?>

save it as continue.php and open it through your browser. The result should be:

1000 divided by -4 is... -250
1000 divided by -3 is... -333.33333333333
1000 divided by -2 is... -500
1000 divided by -1 is... -1000
1000 divided by 1 is... 1000
1000 divided by 2 is... 500
1000 divided by 3 is... 333.33333333333
1000 divided by 4 is... 250
1000 divided by 5 is... 200
1000 divided by 6 is... 166.66666666667
1000 divided by 7 is... 142.85714285714
1000 divided by 8 is... 125
1000 divided by 9 is... 111.11111111111
1000 divided by 10 is... 100

As the result says, we know that the iteration stop temporarily if $i equals to zero and then continue the loop until finish
