Hi guys, I having the same problem also, and I'm using 000webhost also. Below is my code and I can actually insert the data into database but I wonder why the error message is keep showing and very annoying .... :-\ Can anyone help me to identify the problem ? <?php for ($a = 1; $a <= $number ; $a++) { if ((${subject.$a}[1] == "Beta" ) || (${subject.$a}[1] == "beta" )){ $two_hours_lec = (${subject.$a}[2])/2; $one_hour_lec = (${subject.$a}[2])%2; $beta_array_code = ${subject.$a}[0]; $beta_lec = mysql_query("SELECT * FROM slot WHERE subject = '$beta_array_code' AND type = 'lecture' "); while ($beta_result = mysql_fetch_array($beta_lec)) { $beta_section = $beta_result[section]; // for 2 hours class $check_same_day = array(); // to empty the array for ($bs = 1 ; $bs <= $two_hours_lec ; $bs ++ ){ $check_hour2 = 100; // to make sure after one loop, the content in while loop will be executed $count_array = count($beta_slots); $check_first_hour = array(0,0); $check_second_hour = array(0,0); // check whether the element in array[random number + 1] is continuous to the element in array[random number] with the while loop below while ((($check_hour2 - $check_hour1) != 1) || ($check_day1 != $check_day2)) { $check_again = false; $rand = rand(0, $count_array -1); $rand2 = $rand +1; $first_hour = $beta_slots[$rand]; $second_hour = $beta_slots[$rand2]; $check_first_hour = preg_split('#(?<=[a-z])(?=\d)#i', $first_hour); //split the alphabet and number into array where first element is alphabet and 2nd is number $check_second_hour = preg_split('#(?<=[a-z])(?=\d)#i', $second_hour); $check_hour1 = $check_first_hour[1]; $check_hour2 = $check_second_hour[1]; $check_day1 = $check_first_hour[0]; $check_day2 = $check_second_hour[0]; $key = array_search($check_day1 , $check_same_day); if ($key !== false) { $check_hour2 = 100; // again to make sure the while loop will be executed } $first_lec_hour = $check_hour1 * 100; $second_lec_hour = $check_hour2 * 100; } array_push($check_same_day, $check_day1); // Insert the alphabet into the array to prevent the later hours of same section fall in same day $check_day = find_day($first_hour); // mon - fri $insert_first = mysql_query("INSERT INTO ".$beta_array_code." (section,type,day,start) VALUES ('$beta_section','lecture','$check_day','$first_lec_hour')"); $insert_second = mysql_query("INSERT INTO ".$beta_array_code." (section,type,day,start) VALUES ('$beta_section','lecture','$check_day','$second_lec_hour')"); if (isset($insert_first) && isset($insert_second)) {array_splice($beta_slots, $rand , 2);} } // if there is one hour class if ($one_hour_lec != "") { while (!isset($insert_one)) { $count_array1 = count($beta_slots); $rand1 = rand(0, $count_array1 -1); $one_hour = $beta_slots[$rand1]; $check_one_hour = preg_split('#(?<=[a-z])(?=\d)#i', $one_hour); $one_hour_check = $check_one_hour[0]; $key1 = array_search($one_hour_check , $check_same_day); if ($key1 !== false) { continue; } $check_day_1 = find_day($one_hour); $one_lec_hour = $check_one_hour[1] *100; $insert_one = mysql_query("INSERT INTO ".$beta_array_code." (section,type,day,start) VALUES ('$beta_section','lecture','$check_day_1','$one_lec_hour')"); } unset($insert_one); } } } } ?>

Hi can someone explain this code to me ? I really don't understand ..... preg_replace('/([a-zA-Z]).*/', '$1', $variable);
