Hmm. Would you confirm that this code snippet doesn't work for you?
<?
$needle = "&";
$haystack = "Belle & Sebastian";
if (strstr ($haystack, $needle))
{
echo ("strstr() worked<br>");
}
if (strpos ($haystack, $needle))
{
echo ("strpos() worked<br>");
}
?>
Because if it doesn't, I think there's a problem with your install.
BTW, strstr and strpos don't return TRUE if a string is found. strpos
returns an index into $haystack, strstr returns a substring of $haystack.
Maybe you're doing this?
if (strpos ($haystack, $needle) == TRUE)
which would (I would assume) fail. Though PHP plays fast and loose with
types, so it might work.
