[英]How can I create an array of the directory contents in Dropbox with PHP
[英]How can I access the contents of this PHP array?
以下是PHP中要嘗試包含的文件,該文件將數組保存到類中,然后訪問該數組。 如果我在上面運行print_r(),我會得到結果,但是如果我嘗試單獨訪問數組項,我什么也沒有,有人可以幫我嗎?
<?php
// config.class.php
/*
example usages
$config = Config::getInstance(PATH_TO_CONFIG_FILE, FILE_TYPE);
echo $config->url;
echo $config->test;
echo $config->ip;
*/
class Config
{
private static $instance = null;
private $options = array();
/**
* Retrieves php array file, json file, or ini file and builds array
* @param $filepath Full path to where the file is located
* @param $type is the type of file. can be "ARRAY" "JSON" "INI"
*/
private function __construct($filepath, $type = 'ARRAY')
{
switch($type) {
case 'ARRAY':
$this->options = include $filepath;
break;
case 'INI':
$this->options = parse_ini_file($filepath, true);
break;
case 'JSON':
$this->options = json_decode(file_get_contents($filepath), true);
break;
}
}
private function __clone(){}
public function getInstance($filepath, $type = 'ARRAY')
{
if (null === self::$instance) {
self::$instance = new self($filepath, $type = 'ARRAY');
}
return self::$instance;
}
/**
* Retrieve value with constants being a higher priority
* @param $key Array Key to get
*/
public function __get($key)
{
if (isset($this->options[$key])) {
return $this->options[$key];
}
}
/**
* Set a new or update a key / value pair
* @param $key Key to set
* @param $value Value to set
*/
public function __set($key, $value)
{
$this->options[$key] = $value;
}
}
?>
這是config_array.ini.php文件...
<?php
/**
* @Filename config_array.ini.php
* @description Array to return to our config class
*/
return array(
'ip' => $_SERVER['REMOTE_ADDR'],
'url' => 'http://www.foo.com',
'db' => array(
'host' => 'foo.com',
'port' => 3306
),
'caching' => array(
'enabled' => false
)
);
?>
這是我正在嘗試做的...
<?PHP
$config = Config::getInstance('config_array.inc.php', 'ARRAY');
// this does not show anything
echo $config->ip;
// this works
print_r($config);
?>
您擁有的代碼對我來說很好用。
檢查您的PHP版本,此__get在v5.2.0之后受支持
echo $config->ip; // displays fine 127.0.0.1
它返回一個數組,所以使用...
echo $config['ip'];
->用於班級成員。 您沒有類,但有一個數組,因此請使用方括號($ config [xxxx]代替$ config-> xxxx)。
