ryan9402 Posted November 23, 2013 Share Posted November 23, 2013 (edited) So I made a script to print letters on a curve, I already tried looking for an answer on google. Each had different skew values so I broke up the letters into an array and used array combine. I used the foreach function and now it only prints one letter. Example: Input: Hello Output: Helo All help or guidance is appreciated. Thanks, Ryan Is there a way to fix this? Here is the code: <?PHP $place = count($upper_split); if($debug == "1") { print 'The amount of characters is '.$place.'<br />'; print_r ($upper_split); } if($place == "1") { die("Not enough characters!"); } elseif($place == "2") { $p2 = array( "base1", "base2" ); }elseif($place == "3") { $p2 = array( "base1", "base2", "1" ); }elseif($place == "4") { $p2 = array( "-1", "base1", "base2", "1" ); }elseif($place == "5") { $p2 = array( "-2", "-1", "base1", "base2", "1" ); }elseif($place == "6") { $p2 = array( "0" => "-2", "1" => "-1", "2" => "base1", "3" => "base2", "4" => "1", "5" => "2" ); }elseif($place == "7") { $p2 = array( "-3", "-2", "-1", "base1", "base2", "1", "2" ); }elseif($place == "8") { $p2 = array( "-3", "-2", "-1", "base1", "base2", "1", "2", "3" ); }elseif($place == "9") { $p2 = array( "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3" ); }elseif($place == "10") { $p2 = array( "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4" ); }elseif($place == "11") { $p2 = array( "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4" ); }elseif($place == "12") { $p2 = array( "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5" ); }elseif($place == "13") { $p2 = array( "-6", "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5" ); }elseif($place == "14") { $p2 = array( "-6", "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5", "6" ); }elseif($place == "15") { $p2 = array( "-7", "-6", "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5", "6" ); }elseif($place == "16") { $p2 = array( "-7", "-6", "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5", "6", "7" ); }elseif($place == "17") { $p2 = array( "-8", "-7", "-6", "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5", "6", "7" ); }elseif($place == "18") { $p2 = array( "-8", "-7", "-6", "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5", "6", "7", "8" ); }elseif($place == "19") { $p2 = array( "-9", "-8", "-7", "-6", "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5", "6", "7", "8" ); }elseif($place == "20") { $p2 = array( "-9", "-8", "-7", "-6", "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5", "6", "7", "8", "9" ); } if($debug == "1") { print '<br />DEBUG LINE 302<br />'; print_r ($p2); if(empty($p2)) { print 'No items in array!'; print '<h3>Combined Array:</h3> <br />'; $carr = array_combine($upper_split, $p2); print_r($carr); } } foreach (array_combine($upper_split, $p2) as $char => $pos_1) { if($pos_1 == "-9") { $x = "54.2832"; $y = "127.1807"; $skew = "0.0973 -0.4904 0.9809 0.1945"; } elseif($pos_1 == "-8") { $x = "57.3301"; $y = "113.0444"; $skew = "0.1865 -0.4639 0.9279 0.3729"; } elseif($pos_1 == "-7") { $x = "62.9707"; $y = "99.6519"; $skew = "0.265 -0.424 0.848 0.53"; } elseif($pos_1 == "-6") { $x = "70.9082"; $y = "87.3872"; $skew = "0.3305 -0.3752 0.7504 0.6609"; } elseif($pos_1 == "-5") { $x = "80.7759"; $y = "76.5127"; $skew = "0.3831 -0.3214 0.6427 0.7661"; } elseif($pos_1 == "-4") { $x = "92.2236"; $y = "67.1782"; $skew = "0.4242 -0.2648 0.5295 0.8483"; } elseif($pos_1 == "-3") { $x = "104.8765"; $y = "59.5078"; $skew = "0.4552 -0.207 0.4139 0.9103"; } elseif($pos_1 == "-2") { $x = "118.438"; $y = "53.541"; $skew = "0.4774 -0.1488 0.2976 0.9547"; } elseif($pos_1 == "-1") { $x = "132.6865"; $y = "49.2866"; $skew = "0.4917 -0.0905 0.1811 0.9835"; } elseif($pos_1 == "base1") { $x = "147.3794"; $y = "46.7573"; $skew = "0.4989 -0.0329 0.0657 0.9978"; } elseif($pos_1 == "base2") { $x = "162.2515"; $y = "45.9419"; $skew = "0.4994 0.0237 -0.0475 0.9989"; } elseif($pos_1 == "1") { $x = "177.1421"; $y = "46.814"; $skew = "0.4933 0.0813 -0.1626 0.9867"; } elseif($pos_1 == "2") { $x = "191.7734"; $y = "49.3921"; $skew = "0.4802 0.1394 -0.2788 0.9604"; } elseif($pos_1 == "3") { $x = "205.999"; $y = "53.6982"; $skew = "0.4592 0.1978 -0.3955 0.9185"; } elseif($pos_1 == "4") { $x = "219.5259"; $y = "59.7124"; $skew = "0.4297 0.2557 -0.5113 0.8594"; } elseif($pos_1 == "5") { $x = "232.1196"; $y = "67.4126"; $skew = "0.3903 0.3125 -0.6249 0.7807"; } elseif($pos_1 == "6") { $x = "243.4849"; $y = "76.7485"; $skew = "0.3397 0.3669 -0.7338 0.6793"; } elseif($pos_1 == "7") { $x = "253.2744"; $y = "87.6104"; $skew = "0.2763 0.4167 -0.8334 0.5526"; } elseif($pos_1 == "8") { $x = "261.1313"; $y = "99.8262"; $skew = "0.1999 0.4583 -0.9166 0.3998"; } elseif($pos_1 == "9") { $x = "266.7222"; $y = "113.1919"; $skew = "0.112 0.4873 -0.9746 0.2241"; } else{ $error = "Error: The position was not found for place code: [".$pos_1."] [Function 'find_postion' on line 39 functions.php]"; } $font = "'Arial Black'"; $before ='<text transform="matrix('; $after = ')" stroke="#000000" stroke-width="0.5616" font-family="'.$font.'" font-size="36">'.strtoupper($char).'</text> '; $complete = ''.$before.''.$skew.'

Ch0cu3r Posted November 23, 2013 Share Posted November 23, 2013 What is the output of print_r for $upper_split and $p2 It is probably array_combine that is the issue not foreach. However to answer your quest the alternative to foreach would be while loop with each() (see Example #2) or a for loop Quote Link to comment https://forums.phpfreaks.com/topic/284201-alternative-to-foreach/#findComment-1459717 Share on other sites More sharing options...

However to answer your quest the alternative to foreach would be while loop with each() (see Example #2) or a for loop This is the output of print_r is Array ( [0] => -2 [1] => -1 [2] => base1 [3] => base2 [4] => 1 ) Array ( [H] => -2 [e] => -1 [l] => base2 [o] => 1 ) So it looks like the issue is array combine..

Psycho Posted November 23, 2013 Share Posted November 23, 2013 (edited) Off topic: If you find yourself writing what appears to be repetitive code - such as in your series of ifelse() statements to define $p2 - stop - you're doing it wrong. You can replace all of that code with the code below. I didn't test it thoroughly, but I think it's correct. $p2List = array( "-9", "-8", "-7", "-6", "-5", "-4", "-3", "-2", "-1", "base1", "base2", "1", "2", "3", "4", "5", "6", "7", "8", "9" ); $p2ListCount = count($p2List); if($placeCount<2 || $placeCount>$p2ListCount) { die("Invalid number of characters: {$placeCount}!"); } $startIndex = ceil(($p2ListCount-$placeCount) / 2); $p2 = array_slice($p2List, $startIndex, $placeCount); Edited November 23, 2013 by Psycho Quote Link to comment https://forums.phpfreaks.com/topic/284201-alternative-to-foreach/#findComment-1459720 Share on other sites More sharing options...
objnoob Posted November 23, 2013 Share Posted November 23, 2013 No. The issue is your design. An associative array can not have 2 items with the same key. Latter overwrites former. $arr = array('keyone'=>1,'keyone'=>2); get keyone? which keyone? nope. no such which there's only one keyone and it === 2 ..... $arr['keyone'] === 2 Quote Link to comment https://forums.phpfreaks.com/topic/284201-alternative-to-foreach/#findComment-1459721 Share on other sites More sharing options...
Solution Ch0cu3r Posted November 23, 2013 Solution Share Posted November 23, 2013 Oh thats why you are using the letters are keys. The second L letter is over writing the first L letter in the word hello. You should set the positions as the key and the letters as the value. Basically swap the parameters around for when you call array_combine $carr = array_combine($p2, $upper_split); Then the foreach construct becomes (swap $pos_1 and $char around) foreach (array_combine($upper_split, $p2) as $pos_1 => $char) Quote Link to comment https://forums.phpfreaks.com/topic/284201-alternative-to-foreach/#findComment-1459722 Share on other sites More sharing options...
