stristr checking for quotes

[listenmirndt]

i am using stristr to filter out certain characters..
IE
stristr($string, "X") === FALSE

but it dosnt work for an apostrophe...
stristr($string, "'") === FALSE

any ideas?

[dagon]

you don't want stristr() for removing characters use str_replace or preg_replace

[listenmirndt]

i just want to check if the character exists, not remove it....

thanks!

strpos, is the usual way to do that.

[listenmirndt]

$mystring = $_SERVER[QUERY_STRING];
$findme   = "'";
$pos = strpos($mystring, $findme);

the string "'" was not found

i guess my question is more simple...

how do i print an apostrophe?

because echo "'"
or echo '\''

prints "'" or \'

the word "isn't"
for example,
i want to check if there is an apostrophe in it...

thanks

echo "'";

that should print a single apostrophe.
