PHP foreach not looping

Question

I just built a simple foreach loop to run through an array, but nothing is displaying. No php errors by the way.

Can someone tell me why this isn't working?

$test = array (
            "1" => array(
                "name"=>"something"
            ),
            "2" => array(
                "name"=>"something"
            )
        );

foreach ($test as $key => $arr) {
    echo $arr[$key]["name"];
}

Answer 1

只需使用$arr["name"]而不是$arr[$key]["name"] 。

Answer 2

I think you meant...

foreach ($test as $key => $arr) {
    echo $test[$key]["name"];
}

Or, even more simply...

foreach ($test as $key => $arr) {
    echo $arr["name"];
}

Answer 3

foreach ($test as $key => $arr) {
    echo $test[$key]["name"];
}

OR

foreach ($test as $key => $arr) {
    echo $arr["name"];
}

Answer 4

Your array is written in a way that "1" and "2" are values and not keys.

what you need is:

$test = array (
        array(
            "name"=>"something"
        ),
        array(
            "name"=>"something"
        )
    );

also, you have a typo on your foreach. you need $test[$key] and not $arr[$key]

Answer 5

You should use the $key key in the array reference.

foreach ($test as $arr) {
   echo $arr["name"];
}

You can address the field of the array like

foreach ($test as $key=>$arr) {
    $test[$key][$name]
}

but doing so you do not use the direct reference to the inner arrays

Answer 6

Try this,

foreach ($test as $key => $arr) {
    echo $arr["name"];
}

Answer 7

Use

echo $arr["name"];

or

echo $test[$key]["name"];
