php - how to explode a string with multiple delimiters without using preg_split

The task is to split a string by a set of delimiters. pregsplit could be an option but there is an easier way ;-). Why not combine strreplace and explode?

First, we replace all known delimiters with a special (and hopefully unique) string. After that, we have a string with one delimiter, so it became a suitable task for explode. Take a look to the sourcecode below.

<\?php $nl = PHP_EOL;

$string = 'Word1, Word2 , Word3 and Word4 or Word5 oder Wort6 / Word 7 Word-8'; $delimiters = array( ', ', ' , ', ' oder ', ' or ', ' / ', ' und ', ' and ' ); $words = array();

$unionPlaceholder = 'ARTODETOBAZZLINENETUNIONPLACEHOLDER'; $unifiedString = str_replace($delimiters, $unionPlaceholder, $string);

$words = explode($unionPlaceholder, $unifiedString);

echo 'splitting following string:' . $nl . '"' . $string . '"' . $nl; echo '----' . $nl;

foreach ($words as $word) { echo $word . $nl; }

You see, no magic but a possible timesaver. Have fun with it.
