Several applications of PHP explode () function _php Tutorial

Explode () function introduction

The explode () function splits a string into arrays.

Syntax: Explode (separator,string,limit).

• Separator, required. Specifies where to split the string.
• string, required. The string to split.
• Limit, optional. Specifies the maximum number of array elements that are returned.

This function returns an array of strings, each of which is a substring separated by separator as a boundary point.

The separator parameter cannot be an empty string. If separator is an empty string (""), Explode () returns FALSE. If separator contains a value that is not found in a string, explode () returns an array containing a single element in the string.

If the limit parameter is set, the returned array contains a maximum of limit elements, and the last element will contain the remainder of the string.

If the limit parameter is a negative number, all elements except the last-limit element are returned. This feature is new in PHP 5.1.0.
