Re: [PHP-DB] I want to remove the last comma

[YVES SUCAET]

Ah, I forgot the \n newline character you're adding as well. That would
require you to chop off two character instead of one :-)

Here's the adjusted script:

<snip>
  $dir = "images";
  $d = opendir($dir);
  $out = "
  var tinyMCEImageList = new Array(\n";
  while(false != ($entry = readdir($d))) {
      if(preg_match("/(.jpg|.gif|.png)$/", $entry) != false) {
          $out .= "['{$entry}', '{$dir}/{$entry}'],\n";
      }
  }
  $out = substr($out, 0, strlen($out) - 2);   // MY LINE
  $out .= ");\n";
</snip>

hth,

Yves

I tried all this, all i want is something line this

var tinyMCEImageList = new Array(
['1_h_1.gif', 'images/1_h_1.gif'],
['1_h_1.gif', 'images/1_h_1.gif']
);

But this what i got

var tinyMCEImageList = new Array(
['1_h_1.gif', 'images/1_h_1.gif'],
['1_h_1.gif', 'images/1_h_1.gif'],
);

Remember the last commad on the last element. please show some example code
