Laravel 5.5 String Helper Method: snake

The snake helper method replaces all uppercase letters within the string with the lower cased variant prefixed with the given $delimiter. The only exception to this rule is that if the first character of the string is capitalized, it will be replaced by the lower cased variant without the $delimiter being prefixed. Because of this behavior, the entire string will be lower cased. The snake method trims extraneous whitespace from any string being converted.

#Signature

The signature of the snake method is:

1public static snake(
2        $value,
3        $delimiter = '_'
4    );
