I have unix disk output that I want to convert into an associated array for each line so a user can pick with available disks to use for the next vg creation.
Output of current array item. There is only 1 white space between each column I just did some tab's so it was easier to read.
array(11) {
[0]=> string(141) "vg1 LVM 136G /dev/cciss/c0d0p2 N/A N/A LOCAL N/A N/A NO "
[1]=> string(141) "vg2 LVM 1G /dev/mapper/mpath28p1 60060e80166fa70000016fa700000013 /dev/dm-33 R700 LS1000 0013 YES "

I want this to end up something like this. I've been trying different foreach loops but haven't got it to work yet. Any help/suggestions are appreciated.
[0] => name=>vg1 type=>LVM lun_size=>136G mpath_name=>/dev/cciss/c0d0p2 flun_id=>N/A dm_name=>N/A array_type=>LOCAL array_name=>N/A lun_id=>N/A shared=>NO
[1] => name=>vg2 type=>LVM lun_size=>1G mpath_name=>//dev/mapper/mpath28p1 flun_id=>60060e80166fa70000016fa700000013 dm_name=>/dev/dm-33 array_type=>R700 array_name=>LS1000 lun_id=>0013 shared=>NO
[2] => ....etc
Thanks

Answer 1

The solution is:
Loop through the original array elements
Use explode() function to split the string
Store elements in (key,value) pair in a temporary array
Push the temporary array at the appropriate position in the original array.
So your code should be like this:
// suppose $arr is your original array
$arrLength = count($arr);
for($i = 0; $i < $arrLength; ++$i){
$component_arr = explode(" ", $arr[$i]);
$tmp_arr = array();
$tmp_arr['name'] = $component_arr[0];
$tmp_arr['type'] = $component_arr[1];
$tmp_arr['lun_size'] = $component_arr[2];
$tmp_arr['mpath_name'] = $component_arr[3];
$tmp_arr['flun_id'] = $component_arr[4];
$tmp_arr['dm_name'] = $component_arr[5];
$tmp_arr['array_type'] = $component_arr[6];
$tmp_arr['array_name'] = $component_arr[7];
$tmp_arr['lun_id'] = $component_arr[8];
$tmp_arr['shared'] = $component_arr[9];
unset($arr[$i]);
$arr[$i] = $tmp_arr;
}
// display $arr array
var_dump($arr);

If they are tabs you should be able to use:
foreach($array as $row) {
$pieces = explode("\t",$row);
}

Answer 3

The sorting them out is the issue. The following gives me this. I'm not sure if I need to now use another foreach within there a combine of some sort. I'm been looking at examples but haven't found anything that has a string with that many fields.
foreach($disks as $row){
$arraynew = explode("\t", $row);
print_r($arraynew);
}
Array ( [0] => vg00 LVM 136G /dev/cciss/c0d0p2 N/A N/A LOCAL N/A N/A NO )
Array ( [0] => vg01 LVM 1G /dev/mapper/mpath28p1 60060e80013 /dev/dm-33 R700 LS4P991 0013 YES )

Answer 4

If it is accurate that the columns are only separated by 1 white space, I could suggest something along the lines of:
$result = Array();
foreach($main_array as $string){
$array = explode(" ", $string);
//now here you can sort them in the new array however you wish with the appropriate index and value.
}
Explode by space, " ", not tab, "\t"
