I'm quite new tp PHP and I've been working through a book and doing the examples/exercises in it. Occasionally I run up a script that won't work for some reason, normally a typo on my part, but occasionally a typo on their part and I can normally figure out whats wrong with it.
With the following though I just can't see what the problem is. I've tried the book listing and it works fine. Mine should be identicle except for layout and variable naming conventions. It's probably just a [i]little[/i] tiny error but I just can't find it. Any help would be much appreciated.
It's a script that asks the user for some inputs and draws an image on screen. Basically a coloured box with some text coloured/sized etc by the user.
The error I'm geting is:
[quote]Parse error: parse error, unexpected T_VARIABLE, expecting ',' or ';' in /home/webchimp/public_html/php_learn/imageCreateUser.php on line 72[/quote]
The Origional code is:Code: Select all
