PHP explode() function usage and splitting string_PHP tutorial

explode definition and usage
explode() function splits a string is an array.

Syntax
explode(separator,string,limit)

参数	描述
separator	必需。规定在哪里分割字符串。
string	必需。要分割的字符串。
limit	可选。规定所返回的数组元素的最大数目。

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

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

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

If the limit parameter is negative, all but the last -limit elements are returned. This feature is new in PHP 5.1.0.
Tips and Notes
Note: The parameter limit was added in PHP 4.0.1.

Note: Due to historical reasons, although implode() can receive two parameter orders, explode() cannot. You must ensure that the separator parameter comes before the string parameter.

Example

In this example, we will split the string into an array:

Output:

Array
(
[0] => Hello
[1] => world.
[2] => It's
[3] => a
[4] => beautiful
[5] => day.
)
