How do I convert an array to a string in PHP?

The implode() method allow you to concatenate array elements into a single string. To do this, pass an array and a delimiter to the implode() method; the separator will be inserted between the array values. The json_encode() method converts an array to a JSON string. It takes an array as input and returns a JSON representation of the array. The serialize() method takes an array and converts it to a string.
