such as pagination, because some links already have parameters, in addition to the paging information can not discard the original parameters, so to determine whether the link has parameters, and then additional paging information as needed.
The method is simple:
Copy Code code as follows:
(Strpos ($url, '? ')!== false)? ' & ': '? ');
Check to see if the link is included? , if any, such as:
Http://www.test.com/index.php?id=id
Then add a & to the link immediately following it and follow the paging information:
Http://www.jb51.net/index.php?id=id&page=12
If there are no parameters in the link, such as:
http://www.test.com/index.php
You need to add & then follow the paging information:
Http://www.jb51.net/index.php?page=12
A more robust inspection method is attached:
Copy Code code as follows:
<?php
$old _url = $_server["Request_uri"];
Check the link for existence?
$check = Strpos ($old _url, '? ');
If it exists?
if ($check!== false)
{
If? No parameters behind, such as http://www.yitu.org/index.php?
if (substr ($old _url, $check + 1) = = ")
{
You can add additional parameters directly
$new _url = $old _url;
}
else//If there are parameters, such as: http://www.yitu.org/index.php?ID=12
{
$new _url = $old _url. & ';
}
}
else//If not present?
{
$new _url = $old _url.
}
echo $new _url;
?>
