[Resolved] Stripping unwanted chars from a string

[cbj4074]

Hey everyone,

What's the best function (or should I write one?) for stripping any one of a number of unwanted characters from a string?

Say I have the string:

Published "MIS" Standards Group(TM)

where the (tm) is an actual trademark character.

I want to get rid of the double quotes (") and the trademark symbol (TM).

Do I need to know the ASCII values of the characters I want to get rid of?

In either case, what function should I use to do it, and if there's no predefined function, how might I start writing my own?

strip_tags() does exactly what I'm looking for, except, of course, it strips irrelevant characters for this purpose 🙂

Thanks in advance for any help!!!

here's a quick example i knocked up for you to replace the " and ™ symbols ...

<?php

stripchars("test &#039 123 &#0153"); // &#039 is the single quote , &quot would be a double quote.

function stripchars($strString)
{
    $strArray = array( "&#039" , "&#0153");
	$strString = str_replace($strArray, "-", $strString);

echo $strString;
}
?>

That's perfect, exactly what I was looking for 😃 Thank you SO much, gentlemen.

My only other question is: dynamic sysop, you said, "&#039 is the single quote , &quot would be a double quote."

What if these characters are coming from a MySQL database? They won't be HTML markup, but rather, the characters themselves (ASCII?). I don't even want them in the DB to begin with, but it's out of my control.

The basic idea is just to replace the said characters with a blank.

In this case, one can use a wrapper function, but it is also feasible to use the code directly.

function stripchars($str) {
	$chars = array('"', "™");
	return str_replace($chars, '', $str);
}

Your're a real doll, laserlight, works like a charm 😉
