php parse array values

Question

I'm not very good when it comes to arrays so here's probably something very simple but not for me! I'm getting an array of values via POST and I need to parse them and store the values in a table. How should I use the classic parsing such as:

foreach($array as $a) {
  $text = $a->text;
  $name = $a->user->name;
}

etc to parse an array looking like this:

[item] => Array
        (
            [tags] => Array
                (
                    [0] => Bluetooth
                    [1] => WiFi
                    [2] => USB
                )

        )

This is the entire POST array:

Array
(
    [prodid] => 
    [Submit] => Save
    [productcode] => 797987
    [cat_id] => 66
    [brand] => Fysiomed
    [name] =>  asdc asdc asd c
    [productnew] => yes
    [item] => Array
        (
            [tags] => Array
                (
                    [0] => Bluetooth
                    [1] => WiFi
                    [2] => USB
                )

        )

    [size] => 1
    [barcode] => 7979871
    [price] => 233.00
    [priceoffer] => 0.00
    [stock] => 50
    [weight] => 0.30
    [orderby] => 1
)

Answer 1

if(isset($_POST) && !empty($_POST)) {
  foreach($_POST as $key => $value) {
    if($key == 'item') {
      echo $value[$key]['tag'][0]. '<br>';
      echo $value[$key]['tag'][1]. '<br>';
      echo $value[$key]['tag'][2]. '<br>';
    } 
  }
}

Answer 2

if( isset($_POST['item']) && isset($_POST['item']['tags']) ){
  foreach($_POST['item']['tags'] as $tag){
    //do stuff...e.g.
    echo $tag;
  }
}

Looks like your array is shaped like this, check this

$array = array( "item" => array( "tags" => array("Bluetooth", "Wifi", "USB" ) ) );
var_dump($array);

You will see something like this

array(1) {
  ["item"]=>
  array(1) {
    ["tags"]=>
    array(3) {
      [0]=>
      string(9) "Bluetooth"
      [1]=>
      string(4) "Wifi"
      [2]=>
      string(3) "USB"
    }
  }
}

Now for parsing this array,

foreach($array as $in => $val) {
    // as $array has key=>value pairs, only one key value pair
    // here $in will have the key and $val will have the value
    // $in will be "item"
    print $in; // this will print "item"
    foreach($val as $in2 => $val2 ){
        // only one key : "tags"
        print $in; // this will print "tags"
        print $val2[0];  // this will print "Bluetooth"
        print $val2[1];  // this will print "Wifi"
    } 
}

I hope this clears you doubt regarding arrays.

Are you just trying to get the text out? try this.

foreach($array['item']['tags'] as $tag) {
   $text = $tag;
}
