Factors are integers that can be multiplied together to create a product. Such multiplication sentences are called strings. The length of the string is how many numbers are in it.
6 x 4 is a factor string for 24.
2 x 3 x 4 is a longer factor string for 24.
2 x 2 x 2 x 3 is the longest factor string for 24. The longest factor string is also known as the prime factorization.

How do you check the length of a string in PHP?

What is str split function in PHP?
According to PHP official manual It is used to converts a string to an array.If the optional split_length parameter is specified, the returned array will be broken down into chunks with each being split_length in length, otherwise each chunk will be one character in length. FALSE is returned if split_length is less than 1.If the split_length length exceeds the length of string, the entire string is returned as the first (and only) array element. Syntax: array str_split ( string string [, int split_length] );Example :< ?php$strW3 = "Hello w3answers";$arrW3 = str_split($strW3 );$arrW3 = str_split($strW3 , 3);print_r($arrW3);print_r($arrW3);?>
