Error Debugging

[mattspriggs28]

Hi,

 

I'm wanting to debug a couple of errors on a live site.

 

I have a form that is filled in and the data is stored in an array, as well as the validation error messages before anything is submitted to the database.

 

What I'm wanting to do is fire the array data in an email to myself so I can see what has been submitted in the form in order to see where a particular error may be occuring.

 

I understand that to output the values of an array you need to use print_r(), but how do I add this output to a variable in order to slot it in the body of an email?

 

Thanks for your help.

print_r() has a second parameter called 'return' and it's a true/false of whether it will print the output or return it. Here's an example taken from the PHP manual page for print_r()

 

<?php
$b = array ('m' => 'monkey', 'foo' => 'bar', 'x' => array ('x', 'y', 'z'));
$results = print_r($b, true); // $results now contains output from print_r
?>
