What is the significance of using the implode function in PHP and how does it help in converting arrays to strings?

The implode function in PHP is significant because it allows you to convert an array into a string by concatenating its elements with a specified delimiter. This is useful when you need to display array values as a single string or when you need to pass an array as a parameter in a query or function that only accepts strings.

// Example of using implode function to convert an array to a string
$array = array('apple', 'banana', 'orange');
$string = implode(', ', $array);
echo $string; // Output: apple, banana, orange
