PHP script to print all the GET & POST variables
Variables are one of the core powers of programming. As PHP programmers, we oftern may find that a $_GET or $_POST variable is not performing properly or the way we expected. This may occur for several reasons such as we made a mistake in the variable name. Sometimes this kind of problem take so much time that lots of time is wasted to correct a single variable!
So, you can use the scripts I have written below and use in your code whenever you suspect that there may be a problem with the variables. These scripts helps you by showing the details of each and every $_GET and $_POST variables in the script.
This is very easy and actually 3 (three) lines of code required.
Below is the code to print all $_GET variables:
<?php
print(‘<pre>’);
print_r($_GET);
print(‘</pre>’);
?>

To print all the $_POST variables, we need to change only one line:
<?php
print(‘<pre>’);
print_r($_POST);
print(‘</pre>’);
?>
OK.
You can do it in another way too. It is simple also.
<?php
var_dump($_GET);
?>
Or,
<?php
var_dump($_POST);
?>
So, print your $_GET and $_POST variables whenever you think required.
