simple text convert

[joeblock]

Hi,

Is there a simple way to get all weird charaters out of a string?

i.e. $string = "'¼¶ƒ";

In other words how do you get rid of ALL non-alphanumeric characters from a string?

maybe a regular expression?

Thanks

<?php
$string = "This is some text and numbers 12345 and symbols !£$%^&";
$new_string = ereg_replace("[^A-Za-z0-9]", "", $string);
echo $new_string
?>

Hope this helps...

Hi Ian,

Thanks .. That worked great..

How would I modify that preg_replace so that I could keep certain characters..

i.e.
$string = "http://www.example.com/@hello_there¼¶ƒ_hello the test";

I would like to keep the _:// and get rid of the @ TAB etc

I guess what I need is an url cleanser

Cheers

Joe,

Try something like this:

<?php
$new_string = ereg_replace("[^a-zA-Z0-9!:/.]", "", $string);
?>

Hope that helps.

Hi Ian,

I tried this
<?php
$string = "http://www.example.com/@hello_there¼¶ƒhello the test¬!-";
$new_string = ereg_replace("[^A-Za-z/-9.-]", "", $string);
?>
and it gave this
http//www.example.com/hello_there_hellothetest-

Can you see anything wrong with this? I do not have the !

What are you trying to accomplish? Everything in the expression is an exception, so basically it will remove anything that is not in there.
