Four examples of how PHP URL parameters are obtained

  This article mainly introduces the PHP URL parameter to obtain the way four examples, php URL parameter parsing 4 kinds of methods, the need friend may refer to under

In the case of a known URL parameter, we can use $_get to obtain the corresponding parameter information ($_get[' name ') according to our own situation; then how do I get the parameter information on the URL in the unknown case?   The first, using the $_server built-in array variable   The relatively original $_server[' query_string '] to get the parameters of the URL, usually returned by using this variable will be similar to the data:name=tank& Sex=1 You can use $_server["Request_uri" If you need to include a filename (return similar:/index.php?name=tank&sex=1)   Second, take advantage of pathinfo built-in functions     Code as follows: <?php $test = PathInfo ("http://localhost/index.php"); Print_r ($test); /* results are as follows Array (     [dirname] => http://localhost//url path      [basename] => INDEX.P HP  //full file name      [extension] => php  //filename suffix      [filename] => index//file name )/?>     The third, the use of Parse_url built-in functions     code as follows: <?php $test = Parse_url ("Http://localhost/index.php?na Me=tank&sex=1#top "); Print_r ($test); /* results are as follows Array (     [scheme] => http//Use what protocol      [host] => localhost//host name   & nbsp  [path] =>/index.php//path      [query] => namE=tank&sex=1//Transmitted parameters      [fragment] => Top//back root anchor) * *?>     Fourth, using basename built-in functions &N Bsp     Code as follows: <?php $test = basename ("Http://localhost/index.php?name=tank&sex=1#top"); Echo $test; /* results are as follows Index.php?name=tank&sex=1#top/?>     In addition, it is through the regular matching process to get the desired value. This method is more accurate, the efficiency is not considered ... Below expand practice under the regular processing mode:     code as follows: <?php Preg_match_all ("/(w+=w+) (#w +)?/I", "Http://localhost/index.php?name=tank &sex=1#top ", $match); Print_r ($match); /* results are as follows Array (    [0] => Array         (            [0] => Name=tank             [1] => sex=1#top        )     [1] => Array           (            [0] => Name=tank   & nbsp          [1] => sex=1          )      [2] => ArraY         (             [0] =>         &NBS P   [1] => #top        )] * *?>       long journey ... Still need to dig ...
