    Need regular expression help

    I got the following to match an image tag with a path beginning with a / and replace it with a variable called domain that ends with a /

    $a = eregi_replace(" src=\"/"," src=\"$domain/",$a);

    I want to know how I can write one or more new lines to match a similar image tag path that does not begin with a / and does not begin with a http for example

    <img src="images/someimage.gif">

      Why don't you just do this in .htaccess, or set a <base href=.../>? What you're trying to fix shouldn't really be done that way. However, you can src=\"(/?) to just assume another localized request.

      If you really want a semi-decent way to grab and rewrite your links:
      Code:
      $preg = "/[\s]+[^>]*?src[\s]?=[\s\"\']+(.*?)[\"\']+.*?>/i";
   preg_match_all($preg,  $all_of_content_here, $outvar, PREG_PATTERN_ORDER);
      Then just walk that to fix all hrefs. You can preg, or ereg if you want. I'll try to make that easy for ya with the following sample
      Code:
      foreach ($outvar as $imgsrc) {
  if (eregi($domain, $imgsrc)) {
   // is complete
  } elseif (eregi("^/", $imgsrc)) {
  // starts with a /
  } else {
  // assume it's local
  }
  }
