Analysis of explode function usage in php and phpexplode function usage

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:
Copy codeThe 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:
Copy codeThe 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.
