preg_replace help

[Shantam_Bhavsar]

<?php
$data='123
[test=abc]cba[/test]
321';
$test = preg_replace("(\[test=(.+?)\](.+?)\[\/test\])is","$1",$data);
echo $test;
?>

I expect the above code to return 

abc

but instead of returning abc it returns

123 abc 321

Please tell me where am i wrong.

You start with:

123
[test=abc]cba[/test]
321

then you told it to replace [test=abc]cba[/test] with abc.

 

that leaves

123
abc
321

which, when printed to the browser will show as 123 abc 321

 

 

That is, the numbers (123 and 321) were not matched and therefore not affected by the preg_replace.

Thank you David, 

As per your explanation i changed line no. 5 to $test = preg_replace("(.*\[test=(.+?)\](.+?)\[\/test\].*)is","$1",$data);

and it worked.
