The PHP implode () function combines strings from an array

Definition and usage

The implode () function returns a string that is composed of array elements.

Note: the implode () function accepts two parameter orders. However, for historical reasons, explode () is not possible, and you must ensure that the separator parameter precedes the string parameter.

Note: The separator parameter of the implode () function is optional. However, for backwards compatibility, it is recommended that you use two parameters.

Note: This function is binary safe.
