I’m facing a problem with a simple script I wrote. It has to write out an error if there’s a “<” character in the url.
[code]$url = basename($_SERVER[‘PHP_SELF’]).$_SERVER[‘QUERY_STRING’];
if(strpos($url, “<”) !== FALSE) //found
echo die (“error”);[/code]
Which does the right thing for example:
example.com/< will output an error
while
example.com/?< doesn’t output the error.
Does anyone have any idea how do make “<” display the error even if the ? (question mark) is in front of it.
