Given the following code :
$str = 'CLAX';
echo $str[2]; //prints 'A'
then why should I use str_split( $str ) to convert string to a array of characters ?
I understand str_split( $str , 2 ) will return array of strings; each string being 2 characters long.
分享 This function is to split a string into an array with given string split length
By default string split length is set 1
If you want to split a string into given in given length, then you can use str_split. But in your case you are splitting string with default length 1 that is by you are getting confused.
<?php
$str = "CLAX";
echo $str[2]; //here you are referring to 2 index of string
$arr2 = str_split($str);
Array
(
[0] => C
[1] => L
[2] => A
[3] => X
)
echo $str[2]; //here you are referring to 2 index of an array
<?php
$str = "Hello Friend";
$arr2 = str_split($str, 3);
Array
(
[0] => Hel
[1] => lo
[2] => Fri
[3] => end
)
