For case, Python’s isalnum() technique tin cheque if a quality is alphanumeric, and regenerate() tin substitute circumstantial characters. Likewise, JavaScript gives features similar regenerate() with daily look activity.

Selecting the correct methodology relies upon connected the complexity of the project and the circumstantial programming communication being utilized. For case, if you lone demand to distance areas and regenerate them with hyphens, a elemental regenerate() relation mightiness suffice.

Question & Answer :

However would this beryllium completed? I’ve heard a batch astir daily expressions (regex) being utilized…

This ought to bash what you’re wanting for:

relation cleanable($drawstring) { $drawstring = str_replace(' ', '-', $drawstring); // Replaces each areas with hyphens. instrument preg_replace('/[^A-Za-z0-9\-]/', '', $drawstring); // Removes particular chars. } 

Utilization:

echo cleanable('a|"bc!@£de^&$f g'); 

Volition output: abcdef-g

Edit:

Hey, conscionable a speedy motion, however tin I forestall aggregate hyphens from being adjacent to all another? and person them changed with conscionable 1?

relation cleanable($drawstring) { $drawstring = str_replace(' ', '-', $drawstring); // Replaces each areas with hyphens. $drawstring = preg_replace('/[^A-Za-z0-9\-]/', '', $drawstring); // Removes particular chars. instrument preg_replace('/-+/', '-', $drawstring); // Replaces aggregate hyphens with azygous 1. }
