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

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

The PHP strstr () function 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 is required. Specifies the string to be searched.

Search
Necessary. Specifies the string to search for.
If this parameter is a number, the character that matches the ASCII value corresponding to this number is searched.

Before_search
Optional. The default value is "false" for a Boolean value.
If set to "true", it returns the string portion of the first occurrence of the search parameter.

The sample code is as follows:

<?php Echo strstr ("Welcome to the House of Help", "script"); echo "
"; Echo strstr ("Welcome to Www.jb51.net", "jb51"); echo "
"; Echo strstr ("123456789", "5");? >

The results of the operation are as follows:

Help the Guest House jb51.net56789

Add:

The third optional parameter of the STRSTR () function can be used after the PHP5.3 version, such as:

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