Im working on a table that gives random numbers out and then colorizes them if they can be devided by 2. That works fine. Now i want to get those randomly generated numbers into a second table but sorted. I already managed to put the numbers i generated into an array and sort it but i cant figure out how to echo them 1 by 1 into the table. Maybe you can help me out.

Barand Posted February 20, 2019 Share Posted February 20, 2019 Create a function which outputs data from an array into a table (You do it with the first table so you have some idea how to do it) Generate random array call function to output it sort the array call same function to output it Your html markup is obsolete. I see you have a css file - use it. Quote Link to comment https://forums.phpfreaks.com/topic/308358-beginner-question/#findComment-1564638 Share on other sites More sharing options...
Solence Posted February 20, 2019 Author Share Posted February 20, 2019 (edited) in the first table im generating a random number with each loop which i then put into an array for the second table. So the array is already done. I have no idea how i output an array into a table. At least not the way i want. I only manage to get ether a table with the full array in each field or the same single value of the array in each field. Right now i tried to play around with foreach ($array as &$value); but this just shows me the same number in each field again. I only started a few days ago with php so i barely understand my own code.

Barand Posted February 20, 2019 Share Posted February 20, 2019 (edited) fyi - my solution <?php // generate the array $data = []; for ($i=0; $i<100; $i++) $data[] = mt_rand(1, 99); // output array into table, sort, and output again $t1 = array2table($data); sort($data); $t2 = array2table($data); function array2table(array $arr) { $result = "<table border='1'>\n"; $rows = array_chunk($arr, 10); // split the array into rows of 10 numbers each foreach ($rows as $cols) { // process each row $result .= '<tr>'; foreach ($cols as $c) { // process each column in the current row $cls = $c % 2 ? 'odd':'even'; // apply the appropriate class $result .= "<td class='$cls'>$c</td>"; } $result .= "</tr>\n"; } $result .= "</table>\n"; // return the table return $result; } ?> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Example</title> <style type='text/css'> table { border-collapse: collapse; margin: 20px; display: inline-block; font-family: calibri, sans-serif; font-size: 12pt; } td { width: 20px; height:20px; padding: 2px; text-align: center; } .odd { background-color: #FF8080; } .even { background-color: #C0FFC0; } </style> </head> <body> <?=$t1?> <?=$t2?> </body> </html> Edited February 20, 2019 by Barand typo Quote Link to comment https://forums.phpfreaks.com/topic/308358-beginner-question/#findComment-1564642 Share on other sites More sharing options...
