How to Convert an Array of Strings to an Array of Integers in PHP ?

To convert an array of strings to an array of integers in PHP, you can use the `array_map` function along with `intval` to perform the conversion.

In this example,

We have an array of strings named $strArray containing string representations of integers.
We use the array_map function with intval to convert each element of $strArray to an integer.
The resulting array $intArray contains the converted integers.
We print the contents of $intArray to demonstrate the conversion.

<?php 
$strArray = ["10", "20", "30"];
$intArray = array_map('intval', $strArray);
echo "Converted array of integers: ", json_encode($intArray);
?>

Converted array of integers: [10,20,30]
