what does this mean? +=

Posted on 16th Feb 2014 07:03 pm by admin

is anyone able to explain what this code is saying?

i had it written for me awhile back and now that i wanna change it about to make it my own etc i dont really know what each part is doing... esspecially the += part lol.


im using a form which includes this:

Code: <input type="hidden" name="item_name" value="50 Awake Pills" />

and then from the form above this code is used:

Code: $total = ereg_replace( "[^A-Za-z0-9]", "", $_REQUEST['item_name'] );

$total += 0;

for ( $i = 0; $i < $total; $i++ )
