Explode function in PHP

The explode function is used to split a string into pieces by a specified string i.e. it breaks a string into an array.

The explode function in PHP is used to break a string into smaller text with each break occurring at the similar symbol, commonly called delimiter.
Here in the code below, we are separating the multiple values of the textbox with a comma.

Implode() Function in PHP

The implode function is a function to join the elements of an array with a specific string.

The implode() function joins the strings by taking an array of strings and using a delimiter.
