How Can I Efficiently Filter Multidimensional Arrays for Partial Matches in PHP?

Filtering Multidimensional Arrays for Partial Matches

Searching for specific values within multidimensional arrays can be challenging. To address this issue, we can utilize array_filter to efficiently filter based on partial matches.

Consider the given array containing text and ID key-value pairs. To filter this array for the needle "Bread," we employ array_filter with a custom callback function. The callback compares each element's 'text' value with the search term using strpos. If the search term is found within the 'text' value, the element is retained, otherwise, it is removed.

<?php $search_text = 'Bread';

$filtered_array = array_filter($array, function($el) use ($search_text) {
        return ( strpos($el['text'], $search_text) !== false );
    });
?>

This filtering technique provides a convenient and flexible way to retrieve only the relevant elements from multidimensional arrays based on partial matches. For further details, refer to the documentation for array_filter and strpos.
