[英]how can i access such a php array
我試圖訪問這個PHP數組沒有運氣,我想訪問[icon] => icon.png
Array ( [total] => 2
[total_grouped] => 2
[notifys] => Array ( [0] => Array ( [notifytype_id] => 12
[grouped] => 930
[icon] => icon.png
[n_url] => wall_action.php?id=930
[desc] => 690706096
[text] => Array ( [0] => Sarah O'conner ) [total] => 1 )))
$arr['notifys'][0]['icon']
ETA :我不確定您的評論意味着什么,以下代碼:
$arr = array('total'=>2, 'total_grouped' => 2, 'notifys' => array(array(
'notifytype_id' => 12, 'icon' => 'icon.png')));
echo '<pre>';
print_r($arr);
echo '</pre>';
var_dump($arr['notifys'][0]['icon']);
輸出:
Array
(
[total] => 2
[total_grouped] => 2
[notifys] => Array
(
[0] => Array
(
[notifytype_id] => 12
[icon] => icon.png
)
)
)
string(8) "icon.png"
通常,代碼從不輸出任何內容。 您應該開發所有錯誤和通知。
$arr['notifys'][0]['icon']
rg = Array ( [total] => 2 [total_grouped] => 2 [notifys] => Array ( [0] => Array ( [notifytype_id] => 12 [grouped] => 930 [icon] => icon.png [n_url] => wall_action.php?id=930 [desc] => 690706096 [text] => Array ( [0] => Sarah O'conner ) [total] => 1 )));
icon = rg["notifsys"][0]["icon"];
每個人都在發布正確答案。 它只是你給出了一個錯誤的數組減速。
嘗試使用var_dump
/ print_r
數組,然后就可以輕松理解節點了。
$arr = array(total => 2,
total_grouped => 2,
notifys => array( 0 => array(notifytype_id => 12,
grouped => 930,
icon => 'icon.png',
n_url => 'wall_action.php?id=930',
desc => 690706096,
text =>array(0 => 'Sarah Oconner' ),
total => 1,
),
),
);
echo $arr['notifys']['0']['icon'];
