SORT() an array

[waveol]

Hi,

 

I've got a problem with sorting. The sort() function sorts an array by the values. This function assigns new keys for the elements in the array. Existing keys will be removed. But I need to keep the key as a string. I've got the code:

 

<?php

// print choices for functions

print("<b>Pick a function:</b><br />");

print("<form method=\"post\" action=\"{$_SERVER['PHP_SELF']}\">");

 

?>

<p>

<input type="radio" name="func" value="asort"></input>asort<br />

<input type="radio" name="func" value="arsort"></input>arsort<br />

<input type="radio" name="func" value="ksort"></input>ksort<br />

<input type="radio" name="func" value="sort"></input>sort<br />

 

 

</p>

<p>

<input type="submit" name="set" value="Do it!"></input>

</p>

</form>

<?php

 

if (!empty($_POST['func'])) {

 

$arr_words = array(

"fruit" => "cherry",

"fish" =>  "flounder",

"Animal" => "bear",

"TLA" => "FYI",

"Number" => 25);

 

 

   

switch ($_POST['func']) {

 

    case "asort":

        asort($arr_words);

        print("Function: <b>asort()</b> -- Sort an array and maintain index association<br />\n");

        break;

 

case "sort":

        sort($arr_words);

        print("Function: <b>sort()</b> -- Sort an array and maintain index association<br />\n");

        break;

       

    case "arsort":

        arsort($arr_words);

        print("Function: <b>arsort()</b> -- Sort an array in reverse order and maintain index association<br />\n");

        break;

       

    case "ksort":

        ksort($arr_words);

        print("Function: <b>ksort()</b> -- Sort an array by key<br />\n");

        break;

}

 

// print array to screen

print("Current contents of \$arr_words:<p>\n");

print("<table><tr><td><b>KEY</b></td><td><b>VALUE</b></td></tr>\n");

 

reset($arr_words);

while (list ($key, $val) = each ($arr_words)) {

print("<tr><td>$key</td><td>$val</td></tr>\n");

}

print($_POST);

print("</table></p>");

}

?>

 

 

In the manual mentioned that  - Learners have experienced the problem of properly displaying the

form data in subsequent pages after a sort() function is

invoked. This problem can be avoided by using hidden fields as

shown below.

<input type="hidden" name="array[fruit]" value="<?php print($arr_words["fruit"]); ?>" />

<input type="hidden" name="array[fish]" value="<?php print($arr_words["fish"]); ?>" />

 

I really need help with it, still can't figure out how to do it and how to get the sorting result something as:

 

KEY VALUE

Animal bear

Number 25

TLA FYI

fish flounder

fruit cherry

 

and still using SORT() and the HIDDEN option.

 

Thanks for any help

use asort() instead of sort()

[darkfreaks]

asort ()or usort ()would work i think ???

[MadTechie]

usort is user-defined, but your still loss the keys (i think) if you wanted it to be user-defined then your need to use uasort

 

but asort() is the one you want
