build dynamic arrays

[poe]

i have this bit of code that someone replied to an earlier post:

[code]
for ($i=7; $i<count($myarray); $i+=7) {
    $people[] = array(
        $myarray[0] => $myarray[$i+0],
        $myarray[1] => $myarray[$i+1],
        $myarray[2] => $myarray[$i+2],
        $myarray[3] => $myarray[$i+3],
        $myarray[4] => $myarray[$i+4],
        $myarray[5] => $myarray[$i+5],
        $myarray[6] => $myarray[$i+6]
    );
[/code]



is there a way to build the array dynamiclly without hard coding the array incriments

ie..

for ($i=7; $i<count($myarray); $i+=7) {
    $people[] = array(
        for ($x=0; $x<7; $x++) {
              $myarray[$x] => $myarray[$i+$x],
        }
    );
}

If I understand correctly,

[code]
<?php
$myarray = range(1,70);

$people = array_chunk($myarray, 7);

echo '<pre>', print_r($people, true), '</pre>';
?>
[/code]

ok this is my full code:, just a shrotened version of what i have now.

[code]
<?php
$mystring = "[name][age][pet][mike][22][dog][john][25][cat][kim][26][bird][pam][18][fish]";
$mystring = replace("][",",",$mystring);
$mystring = replace("[","",$mystring);
$mystring = replace("]","",$mystring);
$myarray  = explode(",",$mystring);

for ($i=3; $i<count($myarray); $i+=3) {
    $people[] = array(
        $myarray[0] => $myarray[$i+0],
        $myarray[1] => $myarray[$i+1],
        $myarray[2] => $myarray[$i+2]
    );
}
?>
[/code]

this is the array it produces:

[quote]
Array
(
    [0] => Array (
            [name] => mike
            [age] => 22
            [pet] => dog )
    [1] => Array (
            [name] => john
            [age] => 25
            [pet] => cat )
    [2] => Array (
            [name] => kim
            [age] => 26
            [pet] => bird )
    [3] => Array (
            [name] => pam
            [age] => 18
            [pet] => fish )
)
[/quote]


what i want to do is:

lets say my array has 18 keys
i dont want to repeat typing out  ** $myarray[0] => $myarray[$i+0] **etc... - 18 times or whatever

i was planning on making this into a little function that would split any string into an array the same way. but each string would have different number of keys.

i also want to keep my key names & values intact.

i was looking for a shortcut that i could go:

for($x=1; $x<18; $x++)
$myarray[$x] => $myarray[$i+$x];

...or something


when i refer back to the array i want to use : $key[2]['name']

try
[code]
<?php
function makeArray ($str, $numkeys) {
    $res = array();
    $str = trim($str, '[]');          // remove outer [ and ]
    $tmp = array_chunk(explode('][', $str), $numkeys);
    $k = count($tmp);
    for ($i=1; $i<$k; $i++) {
        for ($j=0; $j<$numkeys; $j++) {
            $res[$i-1][$tmp[0][$j]] = $tmp[$i][$j];
        }
    }
    return $res;
}


$mystring = "[name][age][pet][mike][22][dog][john][25][cat][kim][26][bird][pam][18][fish]";
$data = makeArray($mystring, 3);

echo '<pre>', print_r($data, true), '</pre>';
?>
[/code]

If you just want to indicate how many "keys" there are you could do this:
[code]<?php

$keys = 3; //enter the number of keys there are
$mystring = "[name][age][pet][mike][22][dog][john][25][cat][kim][26][bird][pam][18][fish]";

$mystring = substr($mystring, 1, strlen($mystring)-2);
$myarray  = explode("][",$mystring);

for ($i=1; $i*$keys<count($myarray); $i++) {
   for ($j=0; $j<$keys; $j++) {
       $people[$i-1][$myarray[$j]] = $myarray[($i*$keys)+$j];
   }
}


echo "<pre>";
print_r($people);
echo "</pre>";

?>[/code]

Do you mean 18 People?  Or 18 keys (name, age, pet being three of the keys)?  If 18 people then the same code that you have should do it.

And if you have control over this string, can you format it a little differently?
