ereg_replace function

[benmer]

HI!

I've an problem using the ereg_replace function in PHP4. I want to filter every char which isn't an letter or number out. I use this function but with some chars it says:

REG_EBRACK:brackets ([ ]) not balanced in testuser/test.php4 on line 8

or

Warning: REG_EBRACK: in testuser/test.php4 on line 8

It happens with : [, (, ?, *, +, |
What does I have to do?

$newString = eregi_replace("[^a-z0-9]", "", $oldString)

The bracket is causing a problem because the bracket is used in the ereg function for dealing with atoms. (Which is a pattern enclosed in brackets). So what you have, the function is expecting a closing bracket.

What you need to do is escape the bracket.

So, although I'm not good with the ereg function, you can need to escape the bracket by using the backslash
like this:

I hope that gets you started....
