<pre>
StrStr( <haystack>, <needle>, <before_needle>, <find_last>, <case> )
</pre>

=== Description ===

Find the first/last occurrence of a string

=== Parameters ===

==== haystack ====
The input string.

==== needle ====
If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.

==== before_needle ====
If TRUE, StrStr() returns the part of the haystack before the first/last occurrence of the needle (excluding the needle).

Default: false

==== find_last ====
If TRUE, StrStr() will find the last occurrence of the needle instead of the first.

Default: false

==== case ====
If TRUE, StrStr() will ignore case and do the comparison case insensitively.

Default: false

=== Return Value ===

Returns the portion of string, or FALSE if needle is not found.

=== Remarks ===

None.

=== Example ===

<syntaxhighlight lang="sputnik">
// basic example
$email = 'name@example.com';
$domain = strstr($email, '@');
echo "Value: $domain\n"; // prints @example.com

// using before param to return the text before rather than after the find
$user = strstr($email, '@', true); // As of PHP 5.3.0
echo "Value: $user\n"; // prints name

$string1="google.com";
$newstring=strstr($string1,".");
echo "Value: $newstring\n"; // Prints .COM

// using find last param to find the last substring instead of the first
$string2="google.com.uk";
$newstring1=strstr($string2,".", false, true);
echo "Value: $newstring1\n"; // Prints .COM

// using ignore case param
$string3 = 'cats AnD dogs';
$newstring2 = strstr($string3, 'and', false, false, true);
echo "Value: $newstring2\n"; // prints AnD dogs
