Hi us111,

Regarding to your answer in:
http://www.experts-exchange.com/jsp/qManageQuestion.jsp?ta=php&qid=20272809

I notice that your code is not working with string like

$string="[test]
        word1|
        word2|
        word3
        [/test]";

Any idea,, :(

This works.

<?
function words($mywords)
{
 $line=explode("|",$mywords);
 $newline="<br>";
 for($i=0;$i<count($line);$i++)
 {
      $newline.= ($i+1).":".$line[$i]."<br>";
 }

 return $newline;
}



$string="many lines ....<BR>[test]word1|word2|word3[/test]

                   <BR>
                   many lines ....<BR>
                   <BR>

                   [test]word4|word5[/test]
                   <BR>
                   many lines ....
                   ";




$r = preg_replace("/(.*)(\[test\])(.*)(\[\/test\])(.*)/emx", "words('\\3')", $string);
print $r."\n";
?>

:( The question is if I have more than one line between [test] and [/test]

[test]
       word1|
       word2|
       word3
       [/test]


Try this code for example:
=============================
<?
function words($mywords)
{
$line=explode("|",$mywords);
$newline="<br>";
for($i=0;$i<count($line);$i++)
{
     $newline.= ($i+1).":".$line[$i]."<br>";
}

return $newline;
}



$string="many lines ....<BR>[test]
       word1|
       word2|
       word3
       [/test]

                  <BR>
                  many lines ....<BR>
                  <BR>

                  [test]word4|word5[/test]
                  <BR>
                  many lines ....
                  ";




$r = preg_replace("/(.*)(\[test\])(.*)(\[\/test\])(.*)/emx", "words('\\3')", $string);
print $r."\n";
?>

=============================

Thanks

Oh,

So you have new line inbetween your search string,
in that case you need to add modifier PCRE_DOTALL , (small s)

see this works,

<?
function words($mywords)
{
$line=explode("|",$mywords);
$newline="<br>";
for($i=0;$i<count($line);$i++)
{
    $newline.= ($i+1).":".$line[$i]."<br>";
}

return $newline;
}



$string="many lines ....<BR>[test]
      word1|
      word2|
      word3
      [/test]

                 ";




$r = preg_replace("/(.*)(\[test\])(.*)(\[\/test\])(.*)/emxs", "words('\\3')", $string);
print $r."\n";
?>


But here if you put up text, where multiple [text] [/text] are there, last one would be printed.
