How to convert an array to a string in PHP?

In PHP, the implode function can be used to convert an array into a string.

The example code is provided below:

$array = array('Hello', 'World', '!');
$string = implode(', ', $array);
echo $string; // 输出：Hello, World, !

The implode function takes two parameters: the first parameter is the string used to connect the array elements, and the second parameter is the array to be converted into a string. In the example above, the array elements are connected by a comma and space, resulting in the string “Hello, World, !”.
