多维数组内爆 [英] Multidimensional Array Implode

问题描述

这是我正在处理的多维数组的示例格式:

 数组 ([1] =>数组 ( [code] => PPJ3 [street] => 34412 Fake Street [city] => Detroit [state] => MI [zip] => 48223 [county] => Wayne [cost] => 432.00 )[2] =>数组 ( [code] => PLK3 [street] => 73517 Fake Street [city] => Detroit [state] => MI [zip] => 48223 [county] => Wayne [cost] => 54.00 )[3] =>Array ( [code] => HYK2 [street] => 55224 Fake Street [city] => Detroit [state] => MI [zip] => 48208 [county] => Wayne [cost] => 345.00 ))

我试图将隐藏字段设置为仅代码值并用逗号分隔.数组也需要循环，因为它总是会改变.这是我想要的样子:

$myHiddenField = PPJ3、PLK3、HYK2

有什么简单的编码方法?

解决方案

只要能引用原数组即可..

<块引用>

或用于 csv

Here is an example format of the multidimensional array I'm dealing with:

 Array ( 
    [1] => Array ( [code] => PPJ3 [street] => 34412 Fake Street [city] => Detroit [state] => MI [zip] => 48223 [county] => Wayne [cost] => 432.00 ) 

    [2] => Array ( [code] => PLK3 [street] => 73517 Fake Street [city] => Detroit [state] => MI [zip] => 48223 [county] => Wayne [cost] => 54.00 ) 

    [3] => Array ( [code] => HYK2 [street] => 55224 Fake Street [city] => Detroit [state] => MI [zip] => 48208 [county] => Wayne [cost] => 345.00 ) 
 )

I am trying to set a hidden field to only the code values and have it comma separated. The array would also need to be looped through because it will always change. This is what I would like for it to look like:

$myHiddenField = PPJ3, PLK3, HYK2

What is a simple way of coding this?

解决方案

as long as you can reference the original array ..

<?PHP
$myHiddenField = array();
foreach($array as $row) {
    $myHiddenField [] = $row['code'];
}
?>

or for a csv

<?PHP
foreach($array as $row) {
    $myHiddenField .= ",".$row['code'];
}
$myHiddenField = substr($myHiddenField,1);
?>
