Hi @mokone, after echo $string; I put unset($string);. This is because I will use this code inside a while, and this new line is for $string not contain the last result.<br />

<div class="content wysiwyg-content">
Hi E's, I have two arrays, and these arrays contain words. $array_one contain a single words and $array_two contain more then one word, like:<br />
$array_one ---- Array ( [0] =&gt; one [1] =&gt; two [2] =&gt; five [3] =&gt; ten );<br />
$array_two ---- Array ( [0] =&gt; one four [1] =&gt; one five numbers [2] =&gt; seven eleven [3] =&gt; ten ten world space);<br />
<br />
What I want is a string, that in this case return (the repeat words between arrays divided by space):<br />
$string = &quot;one five ten&quot;;<br />
