shamuraq Posted November 29, 2009 Share Posted November 29, 2009 Hi all, I am trying to create a dynamic number table but keep getting an error during parsing <? $fraction02 = array(); $multiplier = 10; for($i = 0; $i < $multiplier; $i++){ $fraction02[$i] = $i + 1; for($j = 0; $j < $multiplier; $j++){ $fraction02[$i][$j] = ($j + 1) * $i; } echo $fraction02[$i].'<br>'; } ?> The error that i got is: Warning: Cannot use a scalar value as an array in D:\Apache Group\...frac_gen01.php on line 23 Warning: Cannot use a scalar value as an array in D:\Apache Group\...frac_gen01.php on line 23

MadTechie Posted November 29, 2009 Share Posted November 29, 2009 Okay.1 question what is $fraction02[$i] = $i + 1; used for ? Â as that sets $fraction02[$i] to a number BUT you want to use it as an array! Â So i assume you wanted this <?php $fraction02 = array(); $multiplier = 10; for($i = 0; $i < $multiplier; $i++){ //$fraction02[$i] = $i + 1; for($j = 0; $j < $multiplier; $j++){ $fraction02[$i][$j] = ($j + 1) * $i; } //echo ($i+1).'<br>'; } //output - whatever foreach($fraction02 as $K1 => $V1){ echo "<H1>$K1</H1>\n"; foreach($V1 as $K2 => $V2){ echo "$K2 => $V2<br>\n"; } } ?> Quote Link to comment https://forums.phpfreaks.com/topic/183299-array-dynamic-number-table/#findComment-967517 Share on other sites More sharing options...
shamuraq Posted November 29, 2009 Author Share Posted November 29, 2009 i didn't wait for the reply and by chance tuned the code close to urs (MadTechie). <? $fraction02 = array(); $multiplier = 20; for($i = 1; $i < $multiplier; $i++){ for($j = 0; $j < $multiplier; $j++){ $fraction02[$i] = array(); $fraction02[$i][$j] = ($j + 1) * $i; echo $fraction02[$i][$j].", ";//Just to test for result } echo '<br>'; //Just to test for result } ?> Output: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, 114, 120, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119, 126, 133, 140, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136, 144, 152, 160, 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132, 143, 154, 165, 176, 187, 198, 209, 220, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, 13, 26, 39, 52, 65, 78, 91, 104, 117, 130, 143, 156, 169, 182, 195, 208, 221, 234, 247, 260, 14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154, 168, 182, 196, 210, 224, 238, 252, 266, 280, 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300, 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240, 256, 272, 288, 304, 320, 17, 34, 51, 68, 85, 102, 119, 136, 153, 170, 187, 204, 221, 238, 255, 272, 289, 306, 323, 340, 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270, 288, 306, 324, 342, 360, 19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, 247, 266, 285, 304, 323, 342, 361, 380, But this is where the problem starts. When i add a print_r statement: print_r($fraction02); It only shows array [19] of each array: Array ( [1] => Array ( [19] => 20 ) [2] => Array ( [19] => 40 ) [3] => Array ( [19] => 60 ) [4] => Array ( [19] => 80 ) [5] => Array ( [19] => 100 ) [6] => Array ( [19] => 120 ) [7] => Array ( [19] => 140 ) [8] => Array ( [19] => 160 ) [9] => Array ( [19] => 180 ) [10] => Array ( [19] => 200 ) [11] => Array ( [19] => 220 ) [12] => Array ( [19] => 240 ) [13] => Array ( [19] => 260 ) [14] => Array ( [19] => 280 ) [15] => Array ( [19] => 300 ) [16] => Array ( [19] => 320 ) [17] => Array ( [19] => 340 ) [18] => Array ( [19] => 360 ) [19] => Array ( [19] => 380 ) ) What happened to the rest of the values that was initially present during the echoed loop?

wildteen88 Posted November 29, 2009 Share Posted November 29, 2009 This line $fraction02[$i] = array(); Should of been place in the first for loop. Eg   for($i = 1; $i < $multiplier; $i++){    $fraction02[$i] = array();    for($j = 0; $j < $multiplier; $j++){ Quote Link to comment https://forums.phpfreaks.com/topic/183299-array-dynamic-number-table/#findComment-967558 Share on other sites More sharing options...
MadTechie Posted November 29, 2009 Share Posted November 29, 2009 That's be cause your clearing it out  ie look at this and follow the logic $fraction02 = array(); $fraction02[0] = array(); $fraction02[0][1] = "hello"; $fraction02[0] = array(); $fraction02[0][2] = "world"; print_r($fraction02);  So in your code $fraction02[$i] = array(); should be in the previous loop (move it up 2 lines)  Ahhh @ wildteen88, I knew I shouldn't of typed an example!
