The implode () function in PHP returns a string composed of array elements that, contrary to the PHP explode () function, is the PHP explode () function that splits another string with one string and returns an array of strings.

Understanding the function of the PHP implode () function, let's take a look at the syntax of the PHP implode () function and its example.

Grammar

1	implode(separator,array)

Detailed parameters:

Parameters	Description
Separator	Optional. Specifies what is placed between the elements of the array. The default is "" (an empty string).
Array	Necessary. An array to combine as a string.
