Q: How to use str_split() Function In PHP

In this section, we use while loop to count the digits of a Number. First, we declare a counter variable and initialize with 0. Then check the given number is not equal to zero, then divide the number by 10, and increase the counter variable by 1. At last, return the counter variable that display the total digits of a number.

Using while Loop

The str_split() function converts the given string into an array, and then use count() function to count total number of digits in given number.

Example:

PHP

<?php 
  
function countDigits($number) { 
    $digits = str_split($number); 
    $digitCount = count($digits); 
    return $digitCount; 
} 
  
$numStr = '110010'; 
$digitCount1 = countDigits($numStr); 
echo "String Length: " . $digitCount1; 
  
$number = 12345; 
$digitCount2 = countDigits((string)$number); 
echo "\nString Length: " . $digitCount2; 
  
?>

Output

String Length: 6
String Length: 5
