php quik question

what is the function with wich i can see if a string is in other string?

You can use substr_count() to count the number of times a given string is found within another.

[jennycards]

ereg(), eregi()

[Ash@phpFX]

or preg_match()

[natkejs]

strstr($string, "string")

find the first occurance of "string" in $string ... this command is pretty useful.

in your case...

if (strstr($string, "UHH")) { echo "YES.. UHH is in string!" }

thanks for your reply

i want to make an redirect to another page if a string is in the referer page...i've tryed eregi() and strstr() and both times i get same error

this is the code i used:

<?
if (strstr($_SERVER['HTTP_REFERER'], "amateur"))
{ header("location: [url]http://www.mydomain.com/amateur.html[/url]"); die();}
?>

and this is the error i get when i come to this page from another page which the "amateur" in the url:


"Cannot add header information - headers already sent by (output started at /home/..............) "

any ideea why i get this error?

ehm you shouldn't include any html tags there, make it like this.
edit: nevermind this, it's VBulletin adding the html tags even when outputing PHP code.

<?
if (strstr($_SERVER['HTTP_REFERER'], "amateur")) { header("Location: http://www.mydomain.com/amateur.html"); };
?>

also any output command such as echo/print being executed before your re-direct will cause it to fail. so make sure there is nothing in your script that outputs info before it's supposed to re-direct.
