PHP从数组列表中获取值？

Question

In php I am getting an array from the database. When I tried print_r($variable), I got the result like this.

Array
(
    [0] => Array
        (
            [public_name] => Disk space
        )

    [1] => Array
        (
            [public_name] => Color
        )

    [2] => Array
        (
            [public_name] => Processor
        )

)

So here I want to get only the values Disk space, Color, Processor. So can someone kindly tell me how to get those values?

Answer 1

Use

foreach($array as $key=>$val){
  echo $val["public_name"]."<br />";
}

Answer 2

You can use "array_column()" function if you are using PHP 5 >= 5.5.0.

$public_name = array_column($records, 'public_name');
print_r($public_name);

Answer 3

Something like this?

foreach($variable as $row) {
    print $row['public_name'];
}

Use foreach :

foreach($your_array as $a){
  echo $a["public_name"]."<br />";
}

OUTPUT:

Disk space
Color
Processor

Answer 5

When this is a result from a Database why don't you use mysqli_fetch_array

For example:

while ($resultarray = mysqli_fetch_array($variable))
{
echo $resultarray['public_name'];
}
