How to use array_map() and implode() Function In PHP
Using array_map() and implode() function provides a functional approach to generate the HTML list.
- The createList function takes an array as an argument.
- It uses array_map() to apply a callback function to each element of the array, wrapping each item in <li> tags.
- The resulting array of list items is then joined into a single string using implode.
- The function wraps the list items in <ul> tags and returns the resulting HTML string.
Example: This example shows the creation of HTML list from an array using array_map() and implode() Function.
<?php
function createList($arr) {
$listItems = array_map(function($item) {
return '<li>' . htmlspecialchars($item) . '</li>';
}, $arr);
return '<ol>' . implode('', $listItems) . '</ol>';
}
// Driver code
$arr = ['HTML', 'CSS', 'JavaScript', 'PHP'];
echo createList($arr);
?>
Output
<ol><li>HTML</li><li>CSS</li><li>JavaScript</li><li>PHP</li></ol>
