Fetching multidimensional array

despite my efforts I wasn't able to find a suitable solution. Here is the problem:

All the data comes from a form with text fields named name[], gender[], and age[].

print_r($_POST) looks like:

[name] => Array ([2] => Adam [6] => Suzy )
[gender] => Array ( [2] => male [6] => female )
[age] => Array ( [2] => 30 [6] => 25 )

I am trying to iterate it like this:

foreach ($array as $value)
{
echo $value['name'].$value['gender'].$value['age']."<br>";
}

The result should look like this:

Adam - male - 30
Suzy - female - 25

@Being Sunny Veeeery close to that sir I'v used back in 2003. Here is the working solution:

<?
echo "<pre>";
print_r($_POST);
echo "</pre>";


foreach ($_POST['name'] as $key => $name) {
    echo "NAME=".$_POST['name'][$key]."gender=" . $_POST['gender'][$key] . "AGE=".$_POST['age'][$key] . "<br>";
}

?>

WOKSING SOLUTION:
<code>echo "<pre>";
print_r($_POST);
echo "</pre>";


foreach ($_POST['name'] as $key => $name) {
    echo "NAME=".$_POST['nemae'][$key]."gender=" . $_POST['gender'][$key] . "AGE=".$_POST['age'][$key] . "<br>";
}
</code>
<form method="post">
<input type="text" name="name[]" />
<input type="text" name="gender[]"/>
<input type="text" name="age[]"/>
<br />
<input type="text" name="name[]" />
<input type="text" name="gender[]"/>
<input type="text" name="age[]"/>

<input type="submit" />
</form>
</body>
</html>

First of all I've modified the array structure that you posted on your question because it is not valid for in php. Then If I don't misunderstood you requirements then you've this array structure and you want to archive this-

<?php
$array = array (
    'name'=>array('Adam', 'Suzy'),
    'gender'=>array('male', 'female'),
    'age'=>array(30, 25)
);
$i=0;
foreach ($array as $key=>$value)
{   
    if($i==2)break;
    echo $array['name'][$i]."-".$array['gender'][$i] ."-". $array['age'][$i] ."<br>";
    $i++;
}
?>

OR

<?php
$array = array (
    'name'=>array('Adam', 'Suzy'),
    'gender'=>array('male', 'female'),
    'age'=>array(30, 25)
);

foreach ($array['name'] as $index=>$name)
{   
    echo $name."-".$array['gender'][$index] ."-". $array['age'][$index] ."\n";
}
?>

Program Output:

Adam-male-30
Suzy-female-25

Each of the arrays in $_POST have the same set of keys:

$_POST = array(
    'name' =>   array(2 => 'Adam', 6 => 'Suzy'),
    'gender' => array(2 => 'male', 6 => 'female'),
    'age' =>    array(2 => '30',   6 => '25')
)

You can iterate one of the inner arrays, and use its key to access the corresponding values in the other arrays.

foreach ($_POST['name'] as $key => $name) {
    echo $name . $_POST['gender'][$key] . $_POST['age'][$key] . "<br>";
}

You are close - but the syntax for creating arrays is slightly different.

$array = array (
   array('name' => 'Adam', 'gender' => 'male', 'age' => 30),
   array('name' => 'Suzy', 'gender' => 'female', 'age' => 25),
);
foreach ($array as $value)
{
   echo $value['name'].$value['gender'].$value['age']."<br>";
}

You've got two options - you could create an array of two items; each has three details about a single person. That's what I did and it suits the loop you've shown.

Or you can have three parallel arrays - one with two names, one with two genders and one with two ages. That second way would look more like:

$array = array(
  'name' => array('Adam','Suzy'),
  'gender' => array('male','female'),
  'age' =>  array(30,25)
);

But it would be harder to get the output you want from that.

$array2 = array(
  'name' => array('Adam','Suzy'),
  'gender' => array('male','female'),
  'age' =>  array(30,25)
);

for($i=0;$i<count($array2['name']);$i++){
  echo $array2['name'][$i].$array2['gender'][$i].$array2['age'][$i].'<br/>';
}

foreach ($array as $id=>$value)
{
    echo $value . $gender[$id] . $age[$id] . "<br>";
}
