未定义或定义的索引？决定

我有奇怪的问题。

Line 61: $this->_currentRoute = Default_Model_Routes::getInstance()->getCurrentRoute();
.......... other code ..........
Line 86: var_dump(isset($this->_currentRoute['url']));
Line 87: var_dump($this->_currentRoute['url']);
Line 88: if ($this->_currentRoute['url'] == $currentUrl)
Line 89:     $navigation[$key]['active'] = true;
Line 90: var_dump($this->_currentRoute);

这是结果：

bool(true)
string(62) "cs/Polozka-menu-1/Polozka-menu-1-1/Polozka-menu-1-1-1/Clanek-1"
array(17) {
  ["url"]=>
  string(62) "cs/Polozka-menu-1/Polozka-menu-1-1/Polozka-menu-1-1-1/Clanek-1"
  ["type"]=>
  string(7) "article"
  ............
}

在错误日志中：

[09-Mar-2011 19:49:32] PHP Notice:  Undefined index: url in ...file... on line 87
[09-Mar-2011 19:49:32] PHP Notice:  Undefined index: url in ...file... on line 88

如果您有任何想法可能出现问题或如何修复，请告诉我。谢谢:)

我尝试了另一个测试：

$test = array();
echo $test['lol'];

结果是：

Notice: Undefined index: lol in ...file... on line 92

Somethink确实很有趣：这个“lol”错误显示在输出中，但“url”错误不是！它只在日志中...为什么？？？这是同一个文件，位于“url”var_dump() 下的行...疯狂

原文

I have strange problem.

Line 61: $this->_currentRoute = Default_Model_Routes::getInstance()->getCurrentRoute();
.......... other code ..........
Line 86: var_dump(isset($this->_currentRoute['url']));
Line 87: var_dump($this->_currentRoute['url']);
Line 88: if ($this->_currentRoute['url'] == $currentUrl)
Line 89:     $navigation[$key]['active'] = true;
Line 90: var_dump($this->_currentRoute);

This is result:

bool(true)
string(62) "cs/Polozka-menu-1/Polozka-menu-1-1/Polozka-menu-1-1-1/Clanek-1"
array(17) {
  ["url"]=>
  string(62) "cs/Polozka-menu-1/Polozka-menu-1-1/Polozka-menu-1-1-1/Clanek-1"
  ["type"]=>
  string(7) "article"
  ............
}

And in the error log:

[09-Mar-2011 19:49:32] PHP Notice:  Undefined index: url in ...file... on line 87
[09-Mar-2011 19:49:32] PHP Notice:  Undefined index: url in ...file... on line 88

Please, if you have any ideas where could be problem or how to fix, tell me.
Thank you :)

I have tried another test:

$test = array();
echo $test['lol'];

With this result:

Notice: Undefined index: lol in ...file... on line 92

Somethink really interesting: THIS 'lol' error is displayed in output, BUT the 'url' error IS NOT ! It is only in the log ... why ????? It's same file, line under the 'url' var_dump() ... crazy

如果您首先将 `$this->_currentRoute` 分配给变量会发生什么？

$route = $this->_currentRoute;
var_dump(array_key_exists('url', $route));
var_dump(isset($route['url']));
print "PRINTING: ".$route['url'];
die("ENDING ON LINE [".__LINE__."] !!!");

已解决（请参阅评论）

不幸的是，这是 Zend Server 或前沿 PHP 5.3.3 的问题。

What happens if you assign `$this->_currentRoute` to a variable first?

$route = $this->_currentRoute;
var_dump(array_key_exists('url', $route));
var_dump(isset($route['url']));
print "PRINTING: ".$route['url'];
die("ENDING ON LINE [".__LINE__."] !!!");
