thinkphp routing rules using the example detailed and pseudo static function implementation (Apache rewrite) _php instance

Copy Code code as follows:

<?php
thinkphp Routing definition Rules
$route = Array (
' news/:action/:year\d/:month/:d ay ' => ' news/read?year=:2&month=:3&day=:4 ',
' news/:action^delete|update|insert/:year\d/:month/:d ay ' =>array (' News/read?extra=:2&status=1 ', ' year= : 2&month=:3&day=:4 '),
);

$url = ' http://www.test.com/index.php/news/read/2012/2/21/extraparam/test.html ';

Suffix name
$extension = ' html ';

Know: $_server[' path_info '] = ' news/read/2012/2/21/extraparam/test.html ';
$REGX = ' news/read/2012/2/21/extraparam/test.html ';

Looping matching routing rules
foreach ($route as $key => $value) {
If the match succeeds, the match is not continued
if (Parseurlrule ($key, $value, $REGX, $extension))
Break
}

Run Result: Print $_get
Array

The index.php is hidden when deployed, and the Apache rewrite module is turned on
Rewrite rule: rewriterule ^ (. +) $/index.php/$1
When turned on, Apache will automatically convert http:/www.test.com/news/read/2012/2/21/extraparam/test.html to http:/www.test.com/index.php/ News/read/2012/2/21/extraparam/test.html

/**

function Parseurlrule ($rule, $route, $REGX, $extension =null) {
Remove suffix name
!is_null ($extension) && $regx = Str_replace ('. ') $extension, ", $REGX);

Split the routing rules and addresses into an array and then match them by item
$RULEARR = explode ('/', $rule);
$REGXARR = explode ('/', $REGX);

$route is passed in the form of an array, the first
$url = Is_array ($route)? $route [0]: $route;
$match =true;

Match detection
foreach ($ruleArr as $key => $value) {
if (Strpos ($value, ': ') ===0) {
if (substr ($value, -2) = = ' \\d ' &&!is_numeric ($REGXARR [$key])) {
$match = false;
Break
}elseif (Strpos ($value, ' ^ ')) {
$STRIPARR = Explode (' | ', Trim (strstr ($value, ' ^ '), ' ^ '));
if (In_array ($REGXARR [$key], $STRIPARR)) {
$match = false;
Break
}
}
Static items are not case-sensitive
}elseif (strcasecmp ($value, $REGXARR [$key])!==0) {
$match = false;
Break
}
}

  //Match succeeded
   if ($match) {
     //writes dynamic variables to array $matches while removing static matches
     foreach ($ruleArr as $key => $value) {
       if ( Strpos ($value, ': ') ===0) {
        //get dynamic variables as array subscript
         if (substr ($value, -2,1) = = ' \ ')
         $ Matchkey = substr ($value, 1,-2);
        elseif ($pos =strpos ($value, ' ^ '))
           $matchKey =substr ($value, 1, $pos-1);
        else
         $ Matchkey = substr ($value, 1);

$matches [$matchKey] = Array_shift ($REGXARR);
}else
Array_shift ($REGXARR); To remove a static match
}

Gets the value in the array, in order to replace it with the child mode
$values = Array_values ($matches);
Regular match substitution, with ' e ' as modifier
$url = preg_replace ('/:(\d+)/e ', ' $values [\\1-1] ', $url);

     //parsing url    format:  grouping/module/operation? key1=value1&key2=value2
      if Strpos ($url, '? ')! ==false) {  
      //grouping/module/operation? key1=value1&key2=value2
        $arr = Parse_url ($url);
        $paths = explode ('/', $arr [' path ']);
       parse_str ($arr [' query '], $QUERYARR);
     }elseif (Strpos ($url, '/')!==false)  //grouping/modules/operations)
         $paths = explode ('/', $url);
     else        //key1=value1&key2=value2
       parse_str ($url, $QUERYARR);

Get Group Module operations
if (!empty ($paths)) {
$var [' actionname '] = Array_pop ($paths);
$var [' modulename '] = Array_pop ($paths);
if (!empty ($paths)) {
$groupList = ' home,admin ';
$temp = Array_pop ($paths);
if (In_array ($temp, Explode (', ', $groupList))
$var [' groupname '] = $temp;
}
}
Merged into a get array for easy global invocation
$_get = Array_merge ($_get, $var);

Merging parameters
if (Isset ($QUERYARR))
$_get = Array_merge ($_get, $QUERYARR);

Match the remaining parameters in the URL
Preg_replace ('/(\w+) \/([^,\/]+)/e ', ' $tempArr [\ ' \\1\ ']=\ ', ' ' \\2\ '], implode ('/', $REGXARR));
if (!empty ($TEMPARR))
$_get = Array_merge ($_get, $TEMPARR);

Route is an array.
if (Is_array ($route)) {
$route [1]=preg_replace ('/:(\d+]/e ', ' $values [\\1-1] ', $route [1]);
Parse_str ($route [1], $var);
$_get = Array_merge ($_get, $var);
Strpos ($url, '? ')! ==false? $der = ' & ': $der = '? ';
Parameters that are eventually written to the $_get, including three parts
1. Remaining parameters of Address bar
2. Parameters in the routing address
3. $route is the second parameter of the array
if (!empty ($TEMPARR))
$var = Array_merge ($TEMPARR, $var);
$url. = $der. Http_build_query ($var);
}
$_get[' finalurl ' = $url;
Ensure $_request can also access
$_request = Array_merge ($_request,$_get);
Results
Print_r ($_get);
return true;
}
return $match;
}

The following is the regular route code:
$rule = '/news\/read\/(\d+) \/(\d+) \/(\d+)/';
$route = ' News/read?year=:1&month=:2&day=:3 ';
