Convert PHP Array to String: Implode Guide

In PHP, you can use the implode() function to convert an array into a string. For example:

<?php
$fruits = array("apple", "banana", "orange");
$string = implode(", ", $fruits);
echo $string; // 输出：apple, banana, orange
?>

In this example, the implode() function combines the elements in the array $fruits with a comma and a space to create a string.
