Question

我想在php中将以下数组转换为字符串。 Implode函数不起作用，因为它是一个多维数组。

$ids = array(array('540'),array('520'));
for($i = 0; $i < count($ids); $i++){
    $CT_IDS[] = $ids[$i];
}
echo implode(',',$CT_IDS);

但输出是Array，Array。我如何得到540和520作为字符串输出？

Answer 1

没有循环：

$ids = array(array('540'),array('520'));
print implode(',', array_map('reset', $ids));
// 540,520

Answer 2

$ids = array(array('540'),array('520'));
for($i = 0; $i < count($ids); $i++){
    $CT_IDS[] = implode(",",$ids[$i]);
}
echo implode(',',$CT_IDS);

Answer 3

非常简单：

foreach ($ids as $id) {
    $CT_IDS[] = $id[0];
}
echo implode(',', $CT_IDS);

Answer 4

尝试 -

$arr = array();
foreach($ids as $id) {
   $arr[] = $id[0]; 
}
echo implode(',', $arr);

Answer 5

使用此代码

$ids = array(array('540'),array('520'));


$CT_IDS = array();

foreach($ids as $val)
{
    foreach($val as $values)
    {
        $CT_IDS[] = $values;
    }   
}
echo implode(',',$CT_IDS);

Answer 6

这适用于您的情况;

$ids = array(array(0=> '540'),array(0 =>'520'));
$CT_IDS = array();
foreach ($ids as $new_arr) $CT_IDS[] = $new_arr[0]; //get the data 
echo $out = implode(', ', $CT_IDS); //and implode the output
