Using a simple regular expressions to check a filename has '.php' onthe end of it

[bizt]

Hi,

Im trying to write a regular expression in PHP to check if a submitted
filename has .php on the end of it. For example, filename.html woulod
return false whereas filename.php would return true.

My code is:

if (ereg ("$.php", $filename))
return true;
else
return false;

Obviously my expression is wrong, could someone please tell me what Im
doing wrong. Thanks

1. Use PCRE not POSIX, the ereg* function will even disappear in PHP6 it
seems.
2. preg_match('/\.php$/',$filename)

A regex is overkill for a simple string. strcmp() is better in this case.

return pathinfo($filename, PATHINFO_EXTENSION) == 'php';

Thanks for this. I had never noticed that pathinfo can return a string
rather than an array.
