Question

$b = array("one", "two", "three");
$z = implode('<', $b);
var_dump($z);

outputs: string(13) “one

can anyone explain this.

PHP 5.4.4

Answer 1

view html source result , the real result is :

string(13) "one<two<three"

as eis mentioned :

This is what it is supposed to do. You are looking at it in your
browser, where it doesn’t show you the results as-is, but tries to
render it as HTML.

so if you want to see it as plain text , simpy filter html tags :

<?php
$b = array("one", "two", "three");
$z = implode('<', $b);
$z = htmlspecialchars($z);
var_dump($z);
