PHP uses the STRSTR () function to get the method of all characters after the specified string _php tips

This example describes how PHP uses the Strstr () function to get all the characters after the specified string. Share to everyone for your reference, specific as follows:

The Strstr () function of PHP searches for the first occurrence of a string in another string, and returns the remainder of the string.

The Strstr () function is defined as follows:

Strstr (String,search,before_search)

Parameter description:

String required. Specify the string to be searched for.

Search
Necessary. Specify the string to search for.
If this parameter is a number, search for characters that match the ASCII value of this number.

Before_search
Optional. The default value is a Boolean value of ' false '.
If set to True, it returns the part of the string before the search parameter first appears.

The sample code is as follows:

<?php
 Echo strstr ("Welcome to the cloud-dwelling community", "script");
 echo "<br/>";
 Echo strstr ("Welcome to Www.jb51.net", "jb51");
 echo "<br/>";
 Echo strstr ("123456789", "5");
? >

The results of the operation are as follows:

Cloud-dwelling Community
jb51.net
56789

Add:

You can use the third optional parameter of the STRSTR () function after the PHP5.3 version, such as:

Echo strstr ("123456789", "5", true);
Output: 1234
