    how to cut a certain group of words in a string?

    Hello there,

    how to cut a certain group of words in a string, for example,
    "<img src='images/smiles/grin.gif' smilietext=':gr in:' border='0'
    style='vertical-align:middle' alt=':grin:' title=':grin:' />"
    "<img src='images/smiles/smile.gif' smilietext=': smile:' border='0'
    style='vertical-align:middle' alt=': smile:' title=': smile:' />"
    ¡­..
    from a forum comment.

    I tried this:
    $subject =$row_Recordset 2['pagetext']
    $pattern="/<img src='images\/smiles\/[a-zA-Z]+\.gif' smilietext=':[a-zA-Z]:'
    border='0' style='vertical-align:middle' alt=':[a-zA-Z]:' title=':[a-zA-Z]:'
    \/>/";
    $result = preg_replace($p attern,"",$subj ect);
    But I failed, I am new to PHP, please help. Thanks very much in advance.

    logically, is it a better way to search for all what is inside the <img ...
    /tag (including numbers) and replace them with ""?
    I will write: $pattern="/<img [a-zA-Z][0-9]>\/>/", is it correct? Thank you
    for your help.

      A couple of tips:

      - You can strip HTML tags with strip_tags() or filter_var().
      - You can sanitize HTML output with a third-party library like HTML

      If you merely want to remove <imgtags then...

      .... try something like:

      $pattern = '@<img\s.*/?>@Uis'; // Not tested

      Just be aware that regexp based HTML parsing tends to fail when faced to
      invalid HTML.
