Attention : Keep in mind that when you want whether there is substring
into string it is better to use strpos()
than to use strstr(). Most times users has problems to differentiate
the cases where the substring is found at position 0
and in the case where it is not found.
Example 2:
$needle = "I love";
$haystack = "I love PHP!";
//using strstr() - bad - exhaust of memory and cpu
if (strstr($haystack, $needle)){
// found
}
//using strpos() - good no exhaust of memory
if (strpos($haystack, $needle) === TRUE){
// found
}
-=-=-=-=-= End of example.

Feel free to write the part you would like to see, submit it to this
bug, and it will hopefully (probably) be added to the documentation.

Is it possible more information to be added to the docs of strstr()
that it is better to look if there is needle in a haystack by using
strpos() - in bold. Even small example.
