訪問二維數組在PHP

我創建了一個二維數組和試圖訪問每一個元素，但我收到的每個陣列的錯誤值。我只可以看到今天作爲值訪問二維數組在PHP

<?php 

$blog = array ( 
     0 => array('by' => "Nilay Mehta", 'on' => "Today", 'id' => "Today", 'post' => "Today"), 
     1 => array('by' => "Nilay Mehta", 'on' => "Today", 'id' => "Today", 'post' => "Today"), 
     2 => array('by' => "Nilay Mehta", 'on' => "Today", 'id' => "Today", 'post' => "Today"), 
     3 => array('by' => "Nilay Mehta", 'on' => "Today", 'id' => "Today", 'post' => "Today"), 
); 

foreach($blog as $blog) 
{ 
    echo "<a href=\"#\">".$blog['by']."</a>"; 
    echo "<div class=\"blogtime\"> - ".$blog['on']."</div>"; 
    echo "<div class=\"blogtime\">Blog Post ID - ".$blog['id']; 
    echo $blog['post']; 
} 
?>

foreach（$ blog as $ blog）!!!!!! –

@MohamadMehdiHabibi - 你的意思是他需要使用'foreach（$ blogs作爲$ blog）'或'foreach（$ blog作爲$ b）'' –

yes @Obmerk Kronen。爲清楚起見。 –

這as $blog將覆蓋原始$blog變量，並且您第一次可以訪問該值，但不會按預期工作。更改第二$blog其他任何事情，因爲我在你的情況做了

foreach($blog as $b) 
{ 
    echo "<a href=\"#\">".$b['by']."</a>"; 
    echo "<div class=\"blogtime\"> - ".$b['on']."</div>"; 
    echo "<div class=\"blogtime\">Blog Post ID - ".$b['id']; 
    echo $b['post']; 
}

的$blog將從

array ( 
     0 => array('by' => "Nilay Mehta", 'on' => "Today", 'id' => "Today", 'post' => "Today"), 
     1 => array('by' => "Nilay Mehta", 'on' => "Today", 'id' => "Today", 'post' => "Today"), 
     2 => array('by' => "Nilay Mehta", 'on' => "Today", 'id' => "Today", 'post' => "Today"), 
     3 => array('by' => "Nilay Mehta", 'on' => "Today", 'id' => "Today", 'post' => "Today"), 
);

到

array('by' => "Nilay Mehta", 'on' => "Today", 'id' => "Today", 'post' => "Today");

+1 ..或爲了清楚起見，使用'$ blogs = array（）'然後'foreach（$ blogs as $ blog）' –

使用foreach($blog as $ind_blog)代替foreach($blog as $blog)，在當前的系統嘗試$blog數組被相同變量的循環的第一次出現所取代。
