php后台多用户权限组思路与实现程序代码分享

<?
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) {
$cachefile = 'op/www.hzhuti.com/'.$name.'.php';
$cachetext = "<?phprn".'$'.$var.'='.arrayeval($values)."rn?>";
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;
}
}
