...a-z, 0-9 and spaces

Anyone? I'm stuck here.

$input = ereg_replace("[^0-9a-Z ]", "", $input);

Think that does it!

Thanks!

Actually Paul F's pattern is incorrect, a-Z is a larger range than what you want.

Just for performance, preg_replace is faster than ereg_replace, though I'm not sure whether using modifiers for case sensitivity is faster or not, in my tests it made marginal difference.

PHP Code:

$input = preg_replace('/[^a-zA-Z0-9 ]/', '', $input); 


Cheers,

BTW, got an e-mail from a friend, he suggested

PHP Code:

preg_replace('/[^0-9a-z ]/i','',$input); 


The i modifier just makes it case insensitive.
