I have the following array in PHP:
Array
(
[0] => Array
(
[name] => category
[value] => OUT
)
[1] => Array
(
[name] => Name_Fr
[value] => p
)
...
How can I get the value if I know the name ?
I tried:
$value = $array['name']['Name_Fr'];
Thanks.
您将必须遍历所有索引,以找到名称匹配的地方。
If you're running PHP 5.5, you can do a lot with array_column() , such as:
$newArray = array_column($oldArray, 'value', 'name');
$value = $newArray[$knownName];
or even (using array dereferencing):
$value = array_column($oldArray, 'value', 'name')[$knownName];
For earlier versions of PHP, you could do something like:
$value = array_filter(
$oldArray,
function ($value) use ($knownName) {
return $value['name'] == $knownName;
}
);
$value = array_shift($value);
echo $value['value'], PHP_EOL;
since it's an array of arrays, a loop would help you do so.
foreach($arrays as $array)
{
$value = $array[value]
}
