>我正在尝试将密码敏感信息存储在单独的.php文件中。 我可以将该文件包含在另一个 php 文件中（我们称之为 php2.php）
问题是，我尝试在 php1 上使用的代码.php不想回显 php2.php 页面中指定的变量。 在数组之外的任何地方，我都可以回显一个变量，它会毫无问题地显示它。 我确定这只是一个语法错误，因为我开始学习PHP。
任何帮助不胜感激！ 谢谢你的关注。
编辑：更新！
这是我尝试使用的整页代码，现在在第 64 行出现错误。

您的方法存在问题：对象的成员属性不接受表达式作为默认值。
我的意思是：
<?php
$foo = 'foo';
$bar = 'bar';
class Clazz {
public $foo = $bar;
static private $_data = array(
'foo' => $foo,
'bar' => $bar
);
}
在这里尝试此代码，自己看看。所有声明都是带有unexpected T_VARIABLE的语法错误。
您的案例需要一种不同的方法，例如初始化方法或在其构造函数中设置$_data的单例。
例子：
<?php
$foo = 'foo';
$bar = 'bar';
class Clazz {
public $foo = '';
static private $_data = array(
'foo' => '',
'bar' => ''
);
static private $_ininiated = false;
static public function init( ) {
if( !self::$_initiated ) {
self::$_data = array(
'foo' => $foo,
'bar' => $bar
);
self::$_initiated = true;
}
}
}
单例示例：
<?php
$foo = 'foo';
$bar = 'bar';
class Clazz {
static private $instance = null;
private $_data = array();
private function __construct( ) {
$this->_data = array(
'foo' => $foo,
'bar' => $bar
);
}
public function getData( $name ) {
return isset($this->data[$name]) ? $this->data[$name] : null;
}
static public function getInstance( ) {
if( self::$instance == null ) {
self::$instance = new self;
}
return self::$instance;
}
}
echo Clazz::getInstance()->getData('foo');
假设您在一个类中有这个（因此允许private static
class Random {
private static $_Data = array(
'db_user' => '',
'db_pass' => '',
'db_host' => '',
'db_name' => '',
'db_table_prefix' => ''
);
public static function SetVar ($Host,$User,$Pass,$DB,$Prefix = null){
self::$_Data['db_user'] = $User;
self::$_Data['db_pass'] = $Pass;
self::$_Data['db_host'] = $Host;
self::$_Data['db_name'] = $DB;
if ($Prefix === null){
self::$_Data['db_table_prefix'] = '';
}else{
self::$_Data['db_table_prefix'] = $Prefix;
}
}
public static function GetInfo(){
return self::$_Data;
}
}
然后按如下方式调用：
Random::SetVar("Test","Test","Test","Test");
print_r(Random::GetInfo());
甚至访问：
echo Random::GetInfo()['db_user'];
但是，如果您使用的是不支持上述调用类型的旧版本的 PHP：
$Var = Random::GetInfo();
echo $Var['db_user'];
