We have often used the function explode() to split a string by a certain string delimeter(eg: ":","~","-","," e.t.c). However,you may seldom come across a situation where you need to split a word letter by letter without any delimeter separating it. There's a simple function "str_split" for this purpose. This function splits a string to an array.

It's usage is given below:

$str = "abcdefgh"; // store value in a variable
$arr1 = str_split($str); //split the string and store its value in an array

echo "

";
print_r($arr1); // print the array
foreach($arr1 as $key=>$val){
        //applying style to individual letters in an array
	echo "$val"; 
}
echo "
"; 


Alternative Method Usage:

 
$str = "abcdefgh"; // store value in a variable
$strlength=strlen($str); // retrieving the length of the string
for($x=0;$x<$strlength;$x++) { // run a loop for the length of the string 
        // print each letter using the substring function and print a string of length 1
	echo "".substr($str,$x,1).""; 
}
