Example 1: Joining Array Elements with a Custom Separator

<?php
$ar = array('apple', 'banana', 'cherry');
echo implode(" - ", $ar);  // Output: apple - banana - cherry
?>

Example 2: Imploding with Empty Strings

<?php
$ar = array('P', 'H', 'P');
echo implode("", $ar);  // Output: PHP
?>

Example 3: Joining Elements from an Associative Array

<?php
$ar = array('name' => 'John', 'age' => 25);
echo implode(", ", $ar);  // Output: John, 25
?>

Example 4: Imploding Multi-Dimensional Arrays

<?php
$multi_array = [['a', 'b'], ['c', 'd']];
foreach ($multi_array as $arr) {
    echo implode(', ', $arr) . '<br>'; // a, b and c, d on separate lines
}
?>

Example 5: Handling Empty Arrays with implode()
