To remove subarrays in an array in PHP, you can use a combination of array functions such as array_filter() and array_values().

Here's an example code snippet that removes subarrays based on a specific condition:

php
<?php
// Sample array with subarrays
$myArray = array(
    array('id' => 1, 'name' => 'John'),
    array('id' => 2, 'name' => 'Jane'),
    array('id' => 3, 'name' => 'Mark'),
    array('id' => 4, 'name' => 'Lisa'),
    array('id' => 5, 'name' => 'Bob'),
    array('id' => 6, 'name' => 'Emma'),
);

// Remove subarrays with id less than 4
$myArray = array_values(array_filter($myArray, function($subarray) {
    return $subarray['id'] >= 4;
}));

// Print the resulting array
print_r($myArray);
?>

In the above example, we first define an array with subarrays $myArray. We then use the array_filter() function to filter out the subarrays that do not meet the condition, which in this case is that the id is less than 4. Finally, we use the array_values() function to re-index the array and get rid of any empty slots.

The resulting array will only contain subarrays with an id greater than or equal to 4.
