How can PHP developers efficiently remove elements from an array based on a specified value?

To efficiently remove elements from an array based on a specified value in PHP, developers can use the array_filter() function. This function allows you to iterate over an array and apply a callback function to each element. The callback function should return true for elements that should be kept and false for elements that should be removed. 

<?php
// Original array
$array = [1, 2, 3, 4, 5];

// Value to remove
$value = 3;

// Remove elements equal to the specified value
$array = array_filter($array, function($element) use ($value) {
    return $element !== $value;
});

print_r($array); // Output: [1, 2, 4, 5]
?>
