derrick katungi Posted September 16, 2011 Author Share Posted September 16, 2011 in the first for loop, change $i++ to $y++.. it should now output something in the third column as well but its not the correct data..

web_craftsman Posted September 16, 2011 Share Posted September 16, 2011 instead of $i <= ($num_rows - 1) use $i < $num_rows Link to comment https://forums.phpfreaks.com/topic/247270-nested-loops-with-arrays/#findComment-1269903 Share on other sites More sharing options...
derrick katungi Posted September 16, 2011 Author Share Posted September 16, 2011 thats true man but i have ever coded in C (borland) and i used to get funny results from $i < $num_rows so i switched to $i <= ($num_rows - 1)..but there's no biggie here, i still have a bigger problem dude.... this is my update so far... <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Second Testing</title> <link href="styler.css" rel="stylesheet" type="text/css" /> </head> <body> <?php error_reporting(0); $num_rows = 16; $number1 = 4; $inn = array(7,10,13,16); $outt = array(14,16,21,23); $numm = array(3,5,7,9); $r_time_in = min($inn); for($i = 0; $i <= $num_rows; $i++) { $new_r_timer_in[$i] = $r_time_in; $new_r_timer_out[$i] = $new_r_timer_in[$i] + 1; $r_time_in += 1; } for($y = 0; $y <= $number1; $y++) { for($i = 0; $i <= ($num_rows - 1); $i++) { if(($inn[$y] <= $new_r_timer_in[$i]) || ($outt[$y] <= $new_r_timer_out[$i])) { $numb[$i] = $numm[$y] + $numm[$y - 1]; } else { $numb[$i] = $numm[$y - 1]; } } } for($i = 0; $i <= ($num_rows - 1); $i++) { echo '<table width="526" border="0"><tr> <td width="169"> <input type="text" name="$r_in[]" value="'.$new_r_timer_in[$i].'" style="width:169px" readonly="readonly" class="text_non_color"/></td> <td width="169"> <input type="text" name="$r_out[]" value="'.$new_r_timer_out[$i].'" style="width:169px" readonly="readonly" class="text_non_color"/></td> <td width="169"> <input type="text" name="$r_num[]" value="'.$numb[$i].'" style="width:169px" readonly="readonly" class="text_non_color"/></td>'; } print("</tr>"); ?> </body> </html> i have "un-commented" the section that had the nested loops and arrays and it outputs something that's definitely wrong Link to comment https://forums.phpfreaks.com/topic/247270-nested-loops-with-arrays/#findComment-1269912 Share on other sites More sharing options...
web_craftsman Posted September 16, 2011 Share Posted September 16, 2011 You are doing several things a bad way 1) do not use bb-code tags for your code listings 2) Loot at what html you will print by your: loop { print '<table><tr><td>...</td>' } print '</tr>'; It is not normat html. Do not you see? Link to comment https://forums.phpfreaks.com/topic/247270-nested-loops-with-arrays/#findComment-1269924 Share on other sites More sharing options...
derrick katungi Posted September 16, 2011 Author Share Posted September 16, 2011 the syntax is OK, at least on my side. i have realized that i have to come up with a completely new algorithm so those nested loops with arrays are based on the wrong algorithm. going to come up with another...enjoy the weekend Link to comment https://forums.phpfreaks.com/topic/247270-nested-loops-with-arrays/#findComment-1269935 Share on other sites More sharing options...
jcbones Posted September 16, 2011 Share Posted September 16, 2011 Need more info. Between the first element of $inn which starts at 7 and ends at 16, and the first element of $outt which starts at 14 and ends at 23. So that would mean you are taking out the last element of $inn. I could help you, but am massively confused. Link to comment https://forums.phpfreaks.com/topic/247270-nested-loops-with-arrays/#findComment-1269937 Share on other sites More sharing options...
derrick katungi Posted September 19, 2011 Author Share Posted September 19, 2011 use this idea, if your age range(7-8,8-9,9-10,etc) falls between $inn[1] and $outt[1] you get $numm[1] which is between 10 and 16, you get 5.

jcbones Posted September 19, 2011 Share Posted September 19, 2011 I think I got the idea: $new_r_timer_in = range(0,10); for($y=0; $y<4;$y++) { if(($inn[$y] <= $new_r_timer_in[$i]) && ($outt[$y] <= $new_r_timer_out[$i])) { echo $numm[$y]; } } Link to comment https://forums.phpfreaks.com/topic/247270-nested-loops-with-arrays/#findComment-1270765 Share on other sites More sharing options...
xyph Posted September 19, 2011 Share Posted September 19, 2011 Similar with foreach(). This assumes count($min) == count($max) == count($res) and that the array keys for each triplet line up correctly. <?php $age = 15; $min = array(7,10,13,16); $max = array(14,16,21,23); $res = array(3,5,7,9); foreach( $res as $key => $num ) { if( $age >= $min[$key] && $age <= $max[$key] ) echo 'Age '.$age.' is between '.$min[$key].' and '.$max[$key].' so result is '.$num.'<br>'; } ?> Link to comment https://forums.phpfreaks.com/topic/247270-nested-loops-with-arrays/#findComment-1270778 Share on other sites More sharing options...
