    explode with the foreach not working (beginner)


    Dear group,
    The function to be used as follows:

    $links = "http://www.campaignind ia.in/feature/analysis";
    $tag1 = '<div class=feature-wrapper>';
    $tag2 = '<h1><a href';
    $tag3 = "</a>";

    $op = doGetTags($link s,"START",$tag1 ,$tag2,$tag3,"E ND");

    return:
    The exploded array of the page of link

    <?php

    function doGetTags()
    {
    $expCounter = 0;
    $numargs = func_num_args() ;
    $toExplode_enco ded = array();
    $link="";
    $condentExplode d = "";
    if ($numargs <= 1)
    {
    echo "The argument can not be less that two";
    die();
    }
    $arg_list = func_get_args() ;
    for($i = 0; $i < $numargs; $i++)
    {
    if($i == 0)
    {
    $link = $arg_list[$i];
    $first_delimite r = $arg_list[++$i];
    for($j=$i; $j < count($arg_list ); $j++)
    {
    if($arg_list[$j] != "START" && $arg_list[$j] != "END")
    {
    $toExplode_enco ded[$expCounter] =
    htmlentities($a rg_list[$j]); // the tag to be exploded and striped
    with attributs
    $expCounter++;
    }
    }
    }

    }
    $aContext = array('http' =array('proxy' =>'tcp://
    192.168.10.131: 8020', 'request_fullur i' =True));
    $cxContext = stream_context_ create($aContex t);
    $fpcont= file_get_conten ts($link, False, $cxContext);


    foreach($toExpl ode_encoded as $key =$val)
    {
    $delimiter = '\''.$val.'\'';
    $condentExplode d = explode($delimi ter,$fpcont);
    print_r($conden tExploded);

    }

    }
    $links = "http://www.campaignind ia.in/feature/analysis";
    $tag1 = '<div class=feature-wrapper>';
    $tag2 = '<h1><a href';
    $tag3 = "</a>";

    $op = doGetTags($link s,"START",$tag1 ,$tag2,$tag3,"E ND");

    ?>

    when I pass the delimiter in explode(), directly for
    example $condentExplode d = explode('<div class=feature-wrapper>',
    $fpcont);
    it working perfectly,the array is exploded. Thanks for any help

      HAve you tried echoing the $delimiter variable just before the
      $condentExplode d = explode($delimi ter,$fpcont);
      statement (no of course I know you didn't, otherwise you would have
      seen what was wrong!)

      Try this foreach instead:
      foreach($toExpl ode_encoded as $key =$val)
      {
      $condentExplode d = explode($val,$f pcont);
      print_r($conden tExploded);

      }

          Thanks for your reply. Yes I did echo the $val and passed the $val
          directly to the explode as like above. It does not work. If I pass the
          direct html delimiter in the explode instead of $val it works. I
          really don't know why. pass-by reference or pass by value problem? I
          am using php5.

                  when I pass the delimiter in explode(), directly for

                  $fpcont);
                  it working perfectly,the array is exploded. Thanks for any help

                      You can avoid HTML encoding the value with htmlentities on the value
                      and enclosing it in quotes... The explode function will want to match
                      the string exactly.

                      If you just want the article links, you can use a simple regexp like
                      [.. good reply snipped..]

                      Thanks a lot for all of you who helped me to learn.
