Solution for php to obtain parameters with special symbols such as # in the URL,

For example the following PHP code:

Copy code The code is as follows:

echo $_GET['key'];
?>

When the url is http://test.com/c.php?key=999, the normal output is: 999
When the url is http://test.com/c.php?key=9#888, it can only output: 9
What I want to get is 9#888, so what should I do? We can only find a way to pass 9#888 to the key.

I solved this problem by encoding and passing the escape function in JS. Friends in need can refer to it.

Copy code The code is as follows:

Query
<script><br> Function searchsn() {<br>          var keys = $('#searchs').val();<br>            if (keys == '') {<br> alert('Please fill in the SN code');<br>               return false;<br> }<br> keys = escape(keys); //Encode the string, except * @ - _ + . / these characters <br>           window.location.href = 'c.php?key=' + keys;<br> }<br> </script>
