PHP破滅數組元素

Question

如何打開下面的數組

$p = array('1' => 'a', '2' => 'b', '3' => 'c'); 

到下面的輸出？需要注意的是每個數組元素是在單獨一行：

1:a 
2:b 
3:c 

Answer 1

您正在尋找的basic for-each construct：

$p = array('1' => 'a', '2' => 'b', '3' => 'c'); 
foreach($p as $key => $value) { 
    echo $key.":".$value."\n"; 
} 

Answer 2

var $colon_separated = array(); 
foreach ($a as $key => $value) { 
    $colon_separated[] = "$key:$value"; 
} 
$result = implode("\n", $colon_separated);
