Why does print_r() display array text?

Question

How can I disable the Array text? Everything works fine, but the Array text of var_dump or at least print_r is not what I want.

array(1) { [0]=> string(21564) "Content" }

This is my code:

<?php

$url = "http://competitive.euw.leagueoflegends.com/de/ladders/euw/current/ranked_team_3x3";

preg_match('#<table class="views-table cols-6"[^>]+>[\w\W]*?</table>#i', file_get_contents($url), $match);
print_r($match);

?>

Array ( [0] => ) <--- This is the ugly part on it which has to be deleted

Add the language, please, or nobody will know what you need. I assume this is PHP? — Sirko

What do you mean "disable the array text"? You want to disable the native functionality of PHP? — hohner

You can use var_export it outputs a valid PHP representation of your variable, if thats what you are after?

Edit: OP wanted to output the result of the preg_match rather than debug it, echo $match[0] was the answer...

Now its array ( 0 => '', ) instead of Array ( [0] => ), doesnt help :<

Your not just seeing array(0 => the first item in that array is your table html markup

If what you want to do is output the table onto your webpage, then you need to do echo $match[0]

Do you know how to replace some content with <span class="brc">content</span>?

Be more specific on what you call array text. If you're talking about the String(5) part then you can just use print_r instead of var_dump otherwise, there's no reason to use either of those functions.

If print_r and var_dump behaviors are the same on your system it must be a PHP plug-in that's modifying the outputs - probably XDebug
