Bug #12120 Updated: Several following < characters ignored by striptags()

ID: 12120 User updated by: michel@eevolved.com Reported By: michel@eevolved.com Old Status: Feedback Status: Open Bug Type: Strings related Operating System: Linux Mandrake PHP Version: 4.0.4pl1 New Comment: I did not try with the newest release, and unfortunatly cannot currently test more with any version (different computer, not suitable for PHP.) Sorry I could not help. Do note, though, that I have been to many, many sites who use PHP, to look into what their solution is to striptags(), and all the sites seem to use a custom function. Obviously, I am not the only one to have this problem (again, as far as 4.0.4pl1 is concerned.)

In a regular browser, it would display the 3 '<' characters, seperated by spaces: "< < <" (equivalent to "&lt; &lt; &lt;") followed by a bold hello. Yet since PHP probably raises a flag after the first "<", all subsequent "<" characters are ignored until the next ">".
