Last update on December 20 2024 10:17:21 (UTC/GMT +8 hours)

Write a PHP function to check whether all array values are strings or not.

Sample Solution:

PHP Code:

<?php
// Function to check if all elements in an array are strings
function check_strings_in_array($arr) 
{
    // Use array_map to check if each element is a string, then sum the results
    // If the sum is equal to the total count of elements, it means all elements are strings
    return array_sum(array_map('is_string', $arr)) == count($arr);
}

// Test arrays
$arr1 = array('PHP', 'JS', 'Python');
$arr2 = array('SQL', 200, 'MySQL');

// Check and display the result for $arr1
var_dump(check_strings_in_array($arr1));

// Check and display the result for $arr2
var_dump(check_strings_in_array($arr2));

?>

Output:

bool(true)                                                  
bool(false)
