So, I created an array, by manually adding each entry:
$Sections[] = "A.1.4.1";//900 0 900 0 900 900 888 800 800 913 900 900 900
$Sections[] = "A.1.4.2.1";// 1000 1000 1000 1000 1000 1000 1000 1000 1000 1000 994 976 954 900 846 779 516 430 344 328 239 150
$Sections[] = "A.1.4.2.2";//900 900 900 900 900 900 900 900 900 900 850 800 750 700 650 600 550 500 376 356 336 227
$Sections[] = "A.1.4.2.3";//1000 1000 1000 1000 900 900 1000 1000 1000 1000 893 803 763 492 516 491 336 336 240 24
$Sections[] = "A.1.4.3";//1000 1000 879 588 560 366 192 867 807 665
$Sections[] = "A.1.4.4";//1000 1000 1000 1000 994 864 620 456 1000 1000 1000
$Sections[] = "A.1.5.1";//900 0 900 800 464
$Sections[] = "A.1.5.2";//a 1000 1000 846 240
$Sections[] = "A.1.5.2";//b 900 900 700 356
$Sections[] = "A.1.5.3";//1000 879 192
$Sections[] = "A.1.5.4";//1012 922 456
//EU_A
$Sections[] = "A.2.5.1";//a 1048 1048 1048 1048 1004 800 576 378
$Sections[] = "A.2.5.1";//b 1048 1048 1048 1048 1004 820 592 384
$Sections[] = "A.2.5.2";//a 1048 1048 964 828 672 504 340
$Sections[] = "A.2.5.2";//b 1048 1048 972 836 696 536 376
$Sections[] = "A.2.5.3";//a 1048 1048 1048 1048 1004 800 576 378
$Sections[] = "A.2.5.3";//b 944 944 944 944 944 820 592 384
$Sections[] = "A.2.5.3";//c 1048 1048 1048 1048 1004 820 592 384

$Sections[] = "A.2.7.1";// 560 504 424 304 240 200
$Sections[] = "A.2.7.2";// 520 448 416 360 312 280
//EU_B
$Sections[] = "B.2.4.1";
$Sections[] = "B.2.4.1";
$Sections[] = "B.2.4.2";
$Sections[] = "B.2.4.2";
$Sections[] = "B.3.4.1";
$Sections[] = "B.3.4.1";
$Sections[] = "B.3.4.2";
$Sections[] = "B.3.4.2";
//TR-114
$Sections[] = "A.2.1";
$Sections[] = "A.2.2";
(You can feel free to ignore the comments, this was literally a cut and paste from my code)
The issue I have is that when I do
return $Sections;
and then try to reference any index, I get an error about it being uninitialized.
However, if I do
$return[] = $Sections;
return $return;
I am easily able to reference the indexes.
I've read the documentation for arrays thoroughly, but I do not understand why it does this. I know it works, I would just like to know why.
I can only assume that when the $Sections array is passed to the $return array, the indexes are somehow "refreshed" or "updated."
Edit: I forgot to mention that this is inside a function, that returns the array created inside. I'm sure everyone would have grasped that pretty quickly, what with the return statement and all
If you are attempting to access the indices as $Sections["B.2.4.1"], that will not work as it's not how you've defined them. By using the [] syntax to append to the array, you are creating numeric indices.
Your array really looks like the following, with each [] appended to the end of the array with a numeric index:
$Sections[0] = "A.1.4.1";
$Sections[1] = "A.1.4.2.1";
