when i print_r($a); the output like this:

Array
(
    [0] => stdClass Object
        (
            [tid] => 3
            [vid] => 1
            [name] => cPanel
            [description] => 
            [format] => 
            [weight] => 0
            [depth] => 0
            [parents] => Array
                (
                    [0] => 0
                )

        )

    [1] => stdClass Object
        (
            [tid] => 4
            [vid] => 1
            [name] => whm
            [description] => 
            [format] => 
            [weight] => 0
            [depth] => 0
            [parents] => Array
                (
                    [0] => 0
                )

        )

    [2] => stdClass Object
        (
            [tid] => 5
            [vid] => 1
            [name] => test
            [description] => 
            [format] => 
            [weight] => 0
            [depth] => 0
            [parents] => Array
                (
                    [0] => 0
                )

        )

)

the array key maybe increment. now, i want to output all the name's value of the array.
when i used the following code. it shows me an error.

foreach($a as $a->name){
    echo a->name;
}

Do this:

foreach($a as $object){
    echo $object->name;
}

Then read this: http://php.net/manual/en/control-structures.foreach.php

Doing:

foreach ($array as $key => $value) {
    echo "Array key: $key   Value: $value";
}

Will print out each value in an array and the name of the key.
