Hello again list.
My code for stripping characters is below. I'm hoping to get feedback
as to how rock solid it will provide the desired output under any
circumstance:
My output must look like this (no quotes):
"This-is-my-string-with-lots-of-junk-characters-in-it"
The code with string looks like this:
$old_string = 'ééééThis is my & $string -- with ƒ
lots˙˙˙of junk characters in it¡™£¢∞§¶•ªºœ∑´®†
¥¨ˆøπ“‘ååååååß∂ƒ©˙∆˚¬…æ`````````__________';
$find = '/[^a-z0-9]/i';
$replace = ' ';
$new_string = preg_replace($find, $replace, $old_string);
$new_string = preg_replace("/ {2,}/", "-", $new_string);
$new_string = preg_replace("/ {1,}/", "-", $new_string);
$new_string = rtrim($new_string, "-");
$new_string = ltrim($new_string, "-");
echo $new_string;
Will the logic above capture and remove every non alpha numeric
character and place a SINGLE hyphen between the non contiguous alpha
numeric characters?
Thanks for the help on this.

It is clean, but as Richard mentioned, it won't handle strings
outside of the traditional 128 ASCII range, so accented characters
and the like will be converted to an underscore. Also, spaces might
become an issue.
However, if you are happy that your input won't go beyond the a-
z0-9 range, then it should do what you need.
No, actually I'm fairly confident characters outside the 128 range
are what are causing me problems now.
So I will try Richard's method.
Thanks to all.
