str_split — Convert a string to an array
$length= 1 ) : array
Converts a string to an array.
The input string.
Maximum length of the chunk.
If the optional
length parameter is
specified, the returned array will be broken down into chunks with each
length in length, otherwise each chunk
will be one character in length.
false is returned if
length is less than 1.
length length exceeds the length of
string, the entire string is returned as the first
(and only) array element.
Example #1 Example uses of str_split()
$str = "Hello Friend";
$arr1 = str_split($str);
$arr2 = str_split($str, 3);
The above example will output:
Array (  => H  => e  => l  => l  => o  =>  => F  => r  => i  => e  => n  => d ) Array (  => Hel  => lo  => Fri  => end )
str_split() will split into bytes, rather than characters when dealing with a multi-byte encoded string.
