Array - Key Value - In a For Loop?

Recommended Posts

I have an array I've created with keys and values as so:

 

$myArray["charley"] = "30";
$myArray["chris"] = "28";
$myArray["kate"] = "25";

 

I was wondering if there's any way to read keys & values from an array like this in a regular for loop somehow? I know how to use a foreach loop, but I want to use a for loop because I need to control how many items from my array appear on the page.

 

PS When I say for loop I mean something like:

 

for ($i = 1; $i <= 10; $i++) {
    echo $i;
}

 

I just don't know the syntax of how to use an array with key / values in a for loop IF it's possible...

 

Thanks

<?php
$myArray["charley"] = "30";
$myArray["chris"] = "28";
$myArray["kate"] = "25";
$key = array_keys($myArray);
for ($i = 0; $i < 3; $i++){
echo $myArray[$key[$i]],"<br />\n";
}
?>

echo $myArray[$key[$i]],"<br />\n";
}
?>

 

Quick question - with this method I can access the value,  but what about the key? Perhaps I should use a regular array instead of key value pairs for what I'm trying to do...?

 

I have pairs of data I'd like to put in a single array - I need to somehow keep the pairs of data together - while maintaining a limit on the number of pairs of data I'll show on the page from the array.

 

Is there any other way to keep pairs of data together with arrays?

Hey Guys,

 

I just came up with one more question for you on this subject - I've tried using the sort function (http://www.php.net/sort) on my array and it seems to wipe out the key but retain the value.

 

Is there any way to sort my array by the value's and retain the keys? My value's will have names in them and I want to make sure they are in alphabetical order no matter where they are added in the array.

 

Thanks
