[Resolved] Explode(help!);

[MaxD]

When I explode a string and then print some of the keys, I'll only get the first letter of the string. e.g. where it would stay "CAR" I'll only get "C"..

This is the function (which work fine except for the second explode)

<?

function display_menu(){

  $gal_idx = file("gal_idx.php");

  foreach($gal_idx as $gal_idx_line){
    if(!eregi("<\?",$gal_idx_line)){
      $gal_idx = explode("|",$gal_idx_line);
      $menu_list[strtolower($gal_idx[1])] = ucfirst(strtolower($gal_idx[1])) . "|" . $gal_idx[2];
    }
  }
  foreach($menu_list as $menu_item){
    $menu_list = explode("|",$menu_item);
    echo "$menu_item[1]   $menu_item[0] <br>\n";
  }
}

any thoughts or known problems?

this part is the trouble:

  foreach($menu_list as $menu_item){
    $menu_list = explode("|",$menu_item);
    echo "$menu_item[1]   $menu_item[0] <br>\n";
  }

Can you give an example of what the file looks like? Don't know why you'd have so many pipes in a php file...

uhm, you're getting only "C" because you are surrounding the varible with brackets [] ..

i don't think you fully understand the foreach loop.

i will give you a idea:

Correct way:

$array = array('word1', 'word2', 'word3');
foreach($array as $var)
{ 
    echo $var. "<br />";

   // output:
   // word1
   // word2
   // word3
}

Incorrect way:

$array = array('word1', 'word2', 'word3');
foreach($array as $var)
{ 
    echo $var[0]. "<br />";
   // output:
   // w
   // w
   // w
}

when you do a foreach on an array it splits up the array and assign them to the variable... so dont use [0] .. [1] ..etc.. its not an array anymore..

you can only use it on the explode since that variable is now an array:

$menu_list = explode("|", $menu_item);

then use

$menu_list[0]

oops. thanks, that was kind of a stupid mistake. I should have known better, but sometimes it take another set of eyes! Thanks again!
