Looping array's

[Ninjakreborn]

I have always wondered how to do this.

Array

Products

  [414]

  [525]

  [3]

  [test1]

  [test2]

  [test3]

  [223]

assume each one has a giant subarray of whatever

foreach ($products as &$k) {

$products['test1'] = 'yes';

$products['test3'] = 'no';

if (is_numeric($k) {

 

}

}

In this situation how can I tell what "k" is set to since I need to access for example

$products['223']['subkey']

Then how would I know which number I was currently at?

[rhodesa]

foreach ($products as $key => $item) {
  if(is_numeric($key)){
    echo $item['subkey'];
  }

}

[tinker]

while (list($k, $v) = each($a))
{
echo $k.": ".$v."<br>";
}

and a way which puts the pointer back at the begining

foreach ($a as $k => $v)
{
echo $k.": ".$v."<br>";
}

AND

 

$array[1]["man"]["head"]="big";

$array[1]["man"]["ear"]="small";

$array[1]["man"]["muchtash"]="gay";

 

$array[2]["man"]["head"]="big";

$array[2]["man"]["ear"]="small";

$array[2]["man"]["muchtash"]="lazered";

 

for($i=0;$i<count($array);$i++){

    echo

    $array[$i]["man"]["head"]="big";

    $array[$i]["man"]["ear"]="small";

    $array[$i]["man"]["muchtash"]="lazered";

}

do {

} while();

 

or do while(){};
