PHP background multi-user permission group ideas and implementation program code_PHP tutorial

Website development is indispensable with a website backend. With the backend, it is natural to assign the same roles to users, especially in the case of a multi-user system. If I have multiple administrators in a system, then my management needs to be divided into, edit, and Friendly connections, administrators, etc., then we need to have permissions and role assignments. Today we will take a look at a system I made before.

First introduce the file,

adminconfig.php This is the permission configuration of all files in the background system.

fun.php This is a functional function

left.php The website background loads the corresponding function menu according to the user's login ID

op.php calls adminconfig.php Default permissions file

opsava.php Save user permissions into a php file

Okay, let’s take a look at the fun.php file first.

The code is as follows

Copy code

代码如下

复制代码

function findsub($keys ,$userid='abc' ) //此函数重要就是为了调用用户的权限信息 { include('user/'.$userid.'.php'); foreach($bb as $key=>$submenu)  {       foreach($submenu  as $subkey=>$menuitem)   {    if( $subkey == $keys )    {     return 1;        }   }    } } //下面为生成用户的php权限文件 //写入 function cache_write($name, $var, $values) {  $cachefile = 'op/user/'.$name.'.php';  $cachetext = "";  if(!swritefile($cachefile, $cachetext))  {   exit("File: $cachefile write error.");  } } //数组转换成字串 function arrayeval($array, $level = 0) { $space = '';  for($i = 0; $i <= $level; $i++) { $space .= "t"; } $evaluate = "Arrayn$space(n"; $comma = $space; foreach($array as $key => $val) {   $key = is_string($key) ? '''.addcslashes($key, ''').''' : $key;   $val = !is_array($val) && (!preg_match("/^-?d+$/", $val) || strlen($val) > 12) ? '''.addcslashes($val, ''').''' : $val;   if(is_array($val)) {    $evaluate .= "$comma$key => ".arrayeval($val, $level + 1);   } else {    $evaluate .= "$comma$key => $val";   }    $comma = ",n$space";  }   $evaluate .= "n$space)";   return $evaluate; } //写入文件 function swritefile($filename, $writetext, $openmod='w') {  if(@$fp = fopen($filename, $openmod)) {   flock($fp, 2);   fwrite($fp, $writetext);   fclose($fp);   return true;  } else {   exit("File: $filename write error.");   return false;  } } ?>

function findsub($keys ,$userid='abc' ) //This function is important to call the user's permission information
{
include('user/'.$userid.'.php');
foreach($bb as $key=>$submenu)
{ 
foreach($submenu as $subkey =>$menuitem)
{
if( $subkey == $keys )
{
return 1;
}
}
}
}//The following is the php permission file to generate the user
//Write
function cache_write($name, $var, $values) {
$cachefile = 'op/user/'.$name.'.php';
$cachetext = "";
if(!swritefile($cachefile, $cachetext))
{
exit("File: $cachefile write error.");
}
}//Convert array into string
function arrayeval($array, $level = 0) {
$space = '';
for( $i = 0; $i <= $level; $i++) {
$space .= "t";
}
$evaluate = "Arrayn$space(n"; < br />$comma = $space;
foreach($array as $key => $val) {
$key = is_string($key) ? '''.addcslashes($key, ' '').''' : $key;
$val = !is_array($val) && (!preg_match("/^-?d+$/", $val) || strlen($val) > ; 12) ? '''.addcslashes($val, ''').''' : $val;
if(is_array($val)) {
$evaluate .= "$comma$ key => ".arrayeval($val, $level + 1);
} else {
$evaluate .= "$comma$key => $val";
} $comma = ",n$space";
}
$evaluate .= "n$space)";
return $evaluate;
}//Write file
function swritefile($filename, $writetext, $openmod='w') {
if(@$fp = fopen($filename, $openmod)) {
flock($fp, 2);
fwrite($fp, $writetext);
fclose($fp);
return true;
} else {
exit("File: $filename write error.");
return false;
}
}?>

adminconfig.php background permission configuration file, saved in the form of an array

The code is as follows

Copy code

代码如下

复制代码

The left.php file is very simple. It reads out the permissions based on the user's ID after logging in.

nr nr ";
}

As shown in the picture

The code is as follows nr nr "; 
}

代码如下	复制代码
$userid = $_SESSION['adminid']; include("op/admincofig.php"); include("op/user/".$userid.".php"); foreach($bb as $key=>$submenu) {      echo "
nr ".$menus[$key]['caption']."
";  foreach($submenu  as $subkey=>$menuitem)  {   $tmparr = explode("|",$menuitem);   echo "4".$tmparr[0]." nr";  }  echo "

Copy code

$userid = $_SESSION['adminid'];
include(" op/admincofig.php");
include("op/user/".$userid.".php");

foreach($bb as $key=>$submenu){ 
echo "

nr ".$menus[$key]['caption']."
< /td>

";
foreach($submenu as $subkey=>$menuitem)
{
$tmparr = explode("|",$menuitem);
echo "4".$tmparr[0]."
nr";
}
echo "

代码如下	复制代码
include("op/fun.php"); if( $_POST ) { $sarray = $_POST ; cache_write($userid,'bb',$sarray);//写入缓存 echo "<script>alert('编辑保存成功！');location='op.php?userid=".$userid."';</script>"; } ?>

op.php This file is to call our adminconfig.php file, and then use the function in the fun.php file to save the provided data into an array as shown in the figure

代码如下	复制代码
$bb=Array ( 'member' => Array   (   'user_search' => '会员升级管理|user_search.php'   ),  'membercy' => Array   (   'cyuser_search' => '会员升级管理|cyuser_search.php',   'cyuser_search5' => '交友会员|cyuser_search.php?grade=5'   ),  'userid' => 7,  'button' => '保存编辑'  ) ?>

Click save and we call opsava.php file, the code is as follows The code is as follows

Copy code

include("op/fun.php");
if( $_POST )
{
$sarray = $_POST ;
cache_write($userid,'bb',$sarray);//Write cache
echo "<script>alert('Edit and save successfully! ');location='op.php?userid=".$userid."';</script>";

}
?> After successful saving, the file content will be as follows

The code is as follows

Copy code

$bb=Array ( 'member' => Array ( 'user_search' => 'Member Upgrade Management|user_search.php' ), 'membercy' => Array ( 'cyuser_search' => 'Member upgrade management|cyuser_search.php', 'cyuser_search5' => 'Dating membership|cyuser_search.php?grade=5' ), 'userid' => ; 7, 'button' => 'Save edit' ) ?> In this case, our left Loading the 7.php file will only display the files here, so that basic background permissions are completed Original tutorial reprinted with source: http://www.bkjia.com/phper. /php.html http://www.bkjia.com/PHPjc/444699.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/444699.htmlTechArticleWebsite development is indispensable with a website backend.
