This article focuses on removing string values from a PHP array using the array_filter() function. It provides a simple example demonstrating how to remove string values from a PHP array. By following these steps, you'll learn how to effectively delete strings from an array in PHP. Let's dive into the process.

We'll use the array_filter() function to achieve this task. Here's a straightforward example of how to remove string values from a PHP array:

// Sample PHP array with mixed data types
$data = [42, 'apple', 56, 'banana', 'cherry'];

// Use array_filter() to remove string values
$result = array_filter($data, function ($value) {
    return !is_string($value);
});

// Display the filtered array
print_r($result);

In this example, we start with a PHP array named $data, which contains a mix of data types, including integers and strings. We then apply the array_filter() function to filter out the string values. The anonymous function within array_filter() checks if a value is not a string using !is_string($value) and retains only non-string values.

The output will be a filtered array containing only non-string values:

Array
(
    [0] => 42
    [2] => 56
)
