Question

Please help me on this.

$str = "col_1          col_2  col_3
row1 row2 row3
row12 row22        row33";

$arr = explode("\n", $str);

foreach($arr as $line)
{
   $temp_arr = explode(WHAT HERE, $line); 
}

How do I explode each line into array??
I want $temp_arr[0] = col_1, $temp_arr[1] = col2, $temp_arr[2] = col_3
next line will have $temp_arr[0] = row1, $temp_arr[1] = row2

You guys are awesome. It works on my example but it doesn’t work on my real problem. I export windows xp processes and want to explode them.

Answer 1

replace

$temp_arr = explode(WHAT HERE, $line);

with

$temp_arr = preg_split('/\s+/', $line, -1, PREG_SPLIT_NO_EMPTY);

Edit: added PREG_SPLIT_NO_EMPTY

OK, so your question changed a bit. This code should do exactly what you want:

$processes = 'the list you posted';

$temp = preg_split('/\s*(?:\r?\n)+/', $processes, -1, PREG_SPLIT_NO_EMPTY);
$process_list = array();
foreach ($temp as $process) {
    $process_list[] = array_pad( // array_pad makes the length consistent
        preg_split(
            '/\s{2,}/', // match only 2 or more consecutive spaces for splitting
            $process,
            3,
            PREG_SPLIT_NO_EMPTY), // ignore empty matches (i.e., end of line)
        3, // pad array to a length of 3
        ''
    );
}

$process_list_final = array();
$process_list_titles = array_shift($process_list);

foreach ($process_list as &$plist_item) {
    $plist_item = array_combine($process_list_titles, $plist_item);
}

It probably needs a bit of cleanup, but you can do that on your own =)

Some functions for you to look up:

• preg_split
• array_pad
• array_shift
• array_combine
