The contains helper method will check if any of the $needles are in the given $haystack. If any of the given $needles are found in the $haystack, the method will return true, otherwise it returns false. $needles can be any value that can be converted into an array, and the $haystack is any value that can be converted to a string. The case of the $haystack and $needles is also important.
The signature for the contains helper function is:
contains($haystack, $needles)
1use Illuminate\Support\Str;
2
3// These are our $needles we want to check for.
4$needles = ['a', 'p', 'l', 'e', 's'];
5
6// true
7Str::contains('apples', $needles);
8
9// false
10Str::contains('APPLES', $needles);
11
12// true
13Str::contains('APPLEs', $needles);
#str_contains($haystack, $needles)
The str_contains function is a shortcut to calling Str::contains. This function is declared in the global namespace.
