removing special characters from many variables

[dougmcc1]

Say I have 20 variables all being submitted from a form by a user. I want to remove the special characters in them.

This doesn't work:

$fields_to_parse=array("var1","other 19 vars");

while (list($null,$field)=each($fields_to_parse)) {

$page_name=ereg_replace("[.,`~!@#$%^{&+=*;'\/():<>?|{}}]","",$field);

}

What's a good way of doing this? Oh, and how do I remove regular brackets?

By the way LordShryku, before you say "I thought you were going to use str_replace", it wouldn't worked with my header. One of the variables is the page name and the header redirects to it. But with str_replace I get sent to 404ville. ereg_replace sends me to $pagename. 🙂

Ran into this one before. You are very close. For simplicity's sake my regexp logic is...

"if it is NOT a space, a-z or 0-9 then take it out"

here is the regexp....(and put in here anything else you wanna keep, maybe .)

[^a-z 0-9]

here is your modified code...

$fields_to_parse=array("var1","other 19 vars");

while (list($null,$field)=each($fields_to_parse)) {

$page_name=eregi_replace("[^a-z 0-9]",'',$field);

}
