Reg. exp. question 1

[Masali]

$s="{This} is a {test} string";
preg_match_all ("/\{.*?\}/", $s, $output);
$re[0]="rep1";
$re[1]="rep2";
print preg_replace($output[0],$re,$s);

Why does this code print out:

{rep1} is a {rep2} string

instead of:

rep1 is a rep2 string

What is wrong?

Probably because preg_replace patterns are delimited by "/"..."/".

Take a look here:

<?php
$s=&quot;{This} is a {test} string&quot;;

preg_match_all (&quot;/\{.*?\}/&quot;, $s, $output);

foreach ($output[0] as $key => $value)
{
	$output[0][$key] = '/' . $value . '/';
}

$re = array (&quot;rep1&quot;, &quot;rep2&quot;);

print preg_replace($output[0],$re,$s);

?>
