Hi,

I want to manuplate every string between [test] and [/test] by explode it and return new string.

For example I have the following string:

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

Then I want to replace :

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

By:

1: word1
2: word2
3: word3


I use:

$string=eregi_replace("\[test\]([^\\[]*)\[/test\]",words('\1'),$string);

where «words» is a function:

function words($mywords){
   $line=explode("|",$mywords);

   $lines="1: $line[0] <BR>  2: $line[1] <BR>  3: $line[2] <BR>";


return $lines;
}



What is wronge in my code ??

Thanks

Thanks,

But what I am looking for is how to explode the match result of eregi_replace!

The code is:

<?

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

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

[test]word1|word2|word3[/test]
<BR>
many lines ....
";

$string=eregi_replace("\[test\]([^\\[]*)\[/test\]",words('\1'),$string);


function words($mywords){
  $line=explode("|",$mywords);

  $lines="1: $line[0] <BR>  2: $line[1] <BR>  3: $line[2] <BR>";


return $lines;
}

echo $string;

?>



The output shoud be like:
==========================

many lines ....
1: word1
2: word2
3: word3

many lines ....

1: word1
2: word2
3: word3

many lines ....



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

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

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

$string=ereg("\[test\]([^\\[]*)\[/test\]",$string, $res);
print words($res[1]);
?>

I think eregi_replace is not an option here.

You should use preg_match_all.

Just an idea.

I've got it worked :

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

Hi us111

I notice that your code is not working with string like

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

Any idea,, :(
