thinkPHP框架动态配置用法实例分析

<?php
return array(
  'setting'=>array(
    'tel' => '400-088-7380',
        'qq'  => '88888888',
        ......
    ),
);
?>

function SaveSetting(){
//setting.config.php文件的路径，通过settingfile_path来设定；
$setfile='./Home'.C('settingfile_path');
$a=C('setting'); //将默认配置参数的内容赋值给$a;
$b=array(
  'tel' => $_POST['tel'],
  'web' => $_POST['web'],
  ........
);
//这里将新的参数值，通过后台的表单提交过来；
$c=array_merge($a,$b) ;

$settingstr="<?php \n return array(\n'Setting' =>array(\n";
foreach($c as $key=>$v){
  $settingstr.= "\t'".$key."'=>'".$v."',\n";
}
$settingstr.="),\n);\n?>\n";
file_put_contents($setfile,$settingstr); //通过file_put_contents保存setting.config.php文件；

$settingstr="<?php \n return array(\n'Setting' =>array(\n";
 foreach($c as $key=>$v){
  $settingstr.= "\t'".$key."'=>'".$v."',\n";
 }
$settingstr.="),\n);\n?>\n";
file_put_contents($setfile,$settingstr); //通过file_put_contents保存setting.config.php文件;

$settingstr = "<?php \n return array(\n'Setting' =>\n".var_export($c,true)." \n ?>";
file_put_contents($setfile,$settingstr); //通过file_put_contents保存

//RUNTIME_FILE常量是入口文件中配置的runtimefile的路径及文件名；
if(file_exists(RUNTIME_FILE)){
  unlink(RUNTIME_FILE); //删除RUNTIME_FILE;
}

$cachedir=RUNTIME_PATH."/Cache/";  //Cache文件的路径；
if ($dh = opendir($cachedir)) {   //打开Cache文件夹；
  while (($file = readdir($dh)) !== false) {  //遍历Cache目录，
       unlink($cachedir.$file);        //删除遍历到的每一个文件；
  }
  closedir($dh);
}
