parsing arrays using foreach

I have an array in the form

$array = array(
    name => array (
        [0] => peter,
        [1] => george,
        [2] => sarah
    ),
    age => array(
        [0] =>1,
        [1] =>2,
        [2] =>3
    )
)

I want to parse it out into a table but when I use a foreach loop I can't seem to get it to output properly.

If I use 

foreach($array[name] as $name){
    foreach($array[age] as $age{

        echo $name.$age;
    }
}

sort of thing then it just outputs the name with each age and then moves to the next name and then does all 3 ages and then the final age..

I want:

Name1 Age1 Name2 Age2 Name3 Age3

foreach (array_keys($array['name']) as $key) {
    echo $array['name'][$key] . $array['age'][$key];
}

Basically, get the sub-array keys from one of your "main" arrays, then use that key inside the loop to extract whatever data you need from the two child arrays.

You can find more detailed information on array_keys here on official documentation.

Use while insted:

$i=0;
$len=count($array['name']);
while($i<$len){
   echo $array['name'][$i].$array['age'][$i];
   ++$i;
}

Use pre-calculations, set the maximum value for your loop before and not in the loop.

Here is the code to your question:

<?php
$array = array(
"name" => array (
0 => "peter",
1 => "george",
2 => "sarah"
),
"age" => array(
0 =>1,
1 =>2,
2 =>3
)
);
$name = $array['name'];
$age = $array['age'];


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

for ($i = 0; $i < count($array['name']); $i++) {    
   echo $array['name'][$i].$array['age'][$i];
}

$array = array(
    'name' => array(
    0 => 'peter',
    1 => 'george',
    2 => 'sarah'
    ),
    'age' => array(
    0 =>'1',
    1 =>'2',
    2 =>'3'
    )
);

foreach($array['name'] as $key => $value)
{
    echo 'Name: ' . $value . ' - Age: ' . $array['age'][$key].'<br />';
}

Edit: Oh, too late :)

Try this:

foreach($array['name'] as $iKey => $name){

echo $name.$array['age'][$iKey];

}
