Exploding Strings with Multiple Delimiters in PHP

Exploding a string into an array is a common task in PHP. However, what if you need to split the string based on multiple delimiters?

Consider the example:

$example = 'Appel @ Ratte';
$example2 = 'apple vs ratte'

You want to explode these strings at either '@' or 'vs' to obtain an array with the split values.

One solution is to use a recursive function like the one provided in the question. However, there is a more efficient approach using regular expressions:

$output = preg_split('/ (@|vs) /', $input);

This regular expression will split the string at any occurrence of either '@' or 'vs', regardless of whether there is whitespace around the delimiter. The () delimit the delimiter pattern, and the | separates the two options.

For example:

$output = preg_split('/ (@|vs) /', $example);
// Result: ['Appel', 'Ratte']

$output = preg_split('/ (@|vs) /', $example2);
// Result: ['apple', 'ratte']
