PHP: Explode A String With Multiple Delimiters.
 

We all know about the famous explode() in php, but this function only accepts one delimiter.. so if you want to split a sentence for example using hyphens (-) fullstops (.) and commas (,) and question marks (?), this might be a little bit of a problem, therefore this function will help you to split a string using multiple delimiters.

try this:

$output = preg_split( "/ (-|.|,|?) /", $input );
