This article analyzes the usage of the explode function in php. Share it with you for your reference. The details are as follows:

Explode (string separator, string [, int limit])

The separator is a null string (""), and explode () returns FALSE. if the value contained in the separator cannot be found in the string, explode () returns an array containing a single string element.

Explode instance 1 with the following code:

The code is as follows:

$ Explode = "aaa, bbb, ccc, ddd, explode, jjjj ";

$ Array = explode (',', $ explode );

Print_r ($ array );
/*
// The result is
Array
(
[0] => aaa
[1] => bbb
[2] => ccc
[3] => ddd
[4] => explode
[5] => JJJJJ
)
*/


We can use the explode function and end function when processing the date or getting the file extension. the following shows the instance code:

The code is as follows:

$ File = "www.jb51.net.gif ";

$ ExtArray = explode ('.', $ file );
$ Ext = end ($ extArray );
Echo $ ext;

// The output value is .gif.


Note: The Separator cannot be a null string, and the string to be split is null.

The Definition and Usage functions are not used. it may be because the delimiter you set does not exist.

I hope this article will help you with PHP programming.
