如何在PHP中用单引号（'）拆分和计算单词？

Question

I want to split word like who's and count it into 2 words like:

who = 1

s = 1

I think, it will use preg_split to do this job, but i don't understand how to do it.

Please any help

Thanks

You may use explode() to get it.

$word= "who's'who";
$results= array();
$parts = explode ("'", $word);
foreach ($parts as $part) $results[$part]++;

You then may output like:

foreach ($results as $word => $count) echo $word . " = " . $count. "<br>";

The output should be:

who = 2

s = 1
