Replacing Special Characters

Anon

I am using a script that builds images with text in them for buttons. I am creating a local file of the image with the button text as the name of the file.

Question: How do I replace all special characters that could be in the name (? ' \ / & # @ ect..) with underscores?

i.e. (Day/Date) to (Day_Date)

Thanks,

Don

Try:

$special_chars = \"?\'\\/&#@\";
$string = eregi_replace( \"[$special_chars]\", \"_\", $string );

or even

$string = eregi_replace( \"[^{[:alnum:]]\",} \"_\", $string );

to replace all non-alphanumerics.
