PHP implode() function

In PHP, conversion of an array to string is done by implode() function. The implode() function puts the separator (In general we use: + , or any other special symbol) between each value of the array. This function joins array elements with a string.

General format of the implode() function is:

i) string implode ( $separator, $array)

ii) string implode ( $array)

iii) string implode ( $array, $separator)

One important point about implode function is that it accepts its parameter in either order, if you don't pass any separator, even any space, PHP wont generate any warning or error message.

General Format	string implode ( $separator, $array)
Parameters	$separator: Any separator like any special symbol (in general)	$array: The array of strings which is to be implode
Return Value	Returns a string with all its elements in same order with a separator between each element
