    ▪PHP JSON 数据解析代码       使用此代码可以顺利解析人人连接网站POST获取的数据。 代码如下: $json_string='{"id":1,"name":"jb51","email":"admin@","interest":["wordpress","php"]} '; $obj=json_decode($json_string); echo $obj->name; //prints foo echo $o.........

代码如下:

function list_files($dir)
{
if(is_dir($dir))
{
if($handle = opendir($dir))
{
while(($file = readdir($handle)) !== false)
{
if($file != "." && $file != ".." && $file != "Thumbs.db")
{
echo '<a target="_blank" href="'.$dir.$file.'">'.$file.'</a><br>'."\n";
}
}
closedir($handle);
}
}
}

代码如下:

/*****
*@dir - Directory to destroy
*@virtual[optional]- whether a virtual directory
*/
function destroyDir($dir, $virtual = false)
{
$ds = DIRECTORY_SEPARATOR;
$dir = $virtual ? realpath($dir) : $dir;
$dir = substr($dir, -1) == $ds ? substr($dir, 0, -1) : $dir;
if (is_dir($dir) && $handle = opendir($dir))
{
while ($file = readdir($handle))
{
if ($file == '.' || $file == '..')
{
continue;
}
elseif (is_dir($dir.$ds.$file))
{
destroyDir($dir.$ds.$file);
}
else
{
unlink($dir.$ds.$file);
}
}
closedir($handle);
rmdir($dir);
return true;
}
else
{
return false;
}
}

代码如下:

$json_string='{"id":1,"name":"jb51","email":"admin@","interest":["wordpress","php"]} ';
$obj=json_decode($json_string);
echo $obj->name; //prints foo
echo $obj->interest[1]; //prints php
