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.
