PHP parsing a file into array
I'm trying to figure out what I'm doing that gives me the wrong result.
I have a file composed this way:
2017/05/02 BA 86 23 39 89 5
2017/05/02 CA 23 4 14 86 5
2017/05/02 FI 71 26 19 15 6
2017/05/02 GE 69 5 16 58 83
2017/05/02 MI 19 45 4 16 68
2017/05/02 NA 6 16 75 78 89
2017/05/02 PA 67 83 21 5 1
2017/05/02 RM 51 79 12 47 19
2017/05/02 RN 27 83 41 37 23
2017/05/02 TO 44 17 60 31 53
2017/05/02 VE 89 32 48 71 57
2017/05/04 BA 61 70 47 71 75
2017/05/04 CA 26 44 16 77 55
2017/05/04 FI 3 11 37 38 18
2017/05/04 GE 70 14 75 86 55
2017/05/04 MI 71 53 39 6 30
2017/05/04 NA 73 20 12 13 54
2017/05/04 PA 37 49 33 80 61
2017/05/04 RM 39 60 75 32 2
2017/05/04 RN 40 78 43 75 55
2017/05/04 TO 24 87 52 90 16
2017/05/04 VE 14 54 25 61 63
2017/05/06 BA 15 31 20 78 66
2017/05/06 CA 84 33 47 9 45
2017/05/06 FI 17 48 33 49 20
2017/05/06 GE 16 51 62 21 72
2017/05/06 MI 12 83 64 62 2
2017/05/06 NA 15 80 52 5 89
2017/05/06 PA 2 33 65 72 61
2017/05/06 RM 29 49 13 70 83
2017/05/06 RN 30 81 55 37 41
As you can see this is formatted this way:
DATE(tab)LETTERS(tab)N1(tab)N2(tab)N3(tab)N4(tab)N5(tab)
The second line has the same date, and changes LETTERS and N_.
I need to insert this file into a DB but this has to have one line for every date, like so:
Date |BA1|BA2|BA3|BA4|BA5|CA1|CA2|CA3|CA4|CA5|FI1|FI2|FI3|FI4|FI5|
-----------------------------------------------------------------
2017/05/02| 86 | 23| 39| 89|5 |23 | 4 | 14|86 |5.....
-----------------------------------------------------------------
2017/05/04|61 |70 |47 |71 |75 |26 |44 |16 |77 |55...
Why my code is not working?
public function caricaStorico(){
$this->load->helper('file');
$storico = read_file(base_url("storico.txt"));
$splitter = explode("\n", $storico);
$data_estr = "-";
$insert = [];
$arr_key = 0;
echo "<pre>";
foreach ($splitter as $key => $value) {
$dati = explode("\t", $value);
if(count($dati)>1) {
$data_estr = $dati[0];
$ruota = $dati[1];
$n1 = $dati[2];
$n2 = $dati[3];
$n3 = $dati[4];
$n4 = $dati[5];
$n5 = $dati[6];
switch ($ruota) {
case 'BA':
array_push($insert, ["data_estrazione" => $data_estr, "BA1" => $n1, 'BA2' => $n2, "BA3" => $n3, "BA4" => $n4, "BA5" => $n5]);
break;
case 'FI':
$insert[$arr_key] += ["FI1" => $n1, 'FI2' => $n2, "FI3" => $n3, "FI4" => $n4, "FI5" => $n5];
break;
case 'MI':
$insert[$arr_key] += ["MI1" => $n1, 'MI2' => $n2, "MI3" => $n3, "MI4" => $n4, "MI5" => $n5];
break;
case 'NA':
$insert[$arr_key] += ["NA1" => $n1, 'NA2' => $n2, "NA3" => $n3, "NA4" => $n4, "NA5" => $n5];
break;
case 'PA':
$insert[$arr_key] += ["PA1" => $n1, 'PA2' => $n2, "PA3" => $n3, "PA4" => $n4, "PA5" => $n5];
break;
case 'RM':
$insert[$arr_key] += ["RM1" => $n1, 'RM2' => $n2, "RM3" => $n3, "RM4" => $n4, "RM5" => $n5];
break;
case 'TO':
$insert[$arr_key] += ["TO1" => $n1, 'TO2' => $n2, "TO3" => $n3, "TO4" => $n4, "TO5" => $n5];
break;
case 'VE':
$insert[$arr_key] += ["VE1" => $n1, 'VE2' => $n2, "VE3" => $n3, "VE4" => $n4, "VE5" => $n5];
break;
case 'RN':
$insert[$arr_key] += ["NZ1" => $n1, 'NZ2' => $n2, "NZ3" => $n3, "NZ4" => $n4, "NZ5" => $n5];
break;
}
}
$arr_key = $arr_key+1;
}
print_r($insert);
echo "</pre>";
}
If I remove the $input[$arr_key] and I do $input[0] I get the right result only on the first array while the others are only containing the BA numbers, as you can see:
Array

[0] => Array

[data_estrazione] => 1939/01/07

You can achive this via using date as a key of array check this out: I used string variable to demonstrate your case so you can change storico variable as you wish.
<?php
function caricaStorico(){
$storico = '2017/05/02 BA 86 23 39 89 5, 2017/05/02 CA 23 4 14 86 5, 2017/05/03 BA 86 23 39 89 5, 2017/05/03 CA 23 4 14 86 5';
$splitter = explode(",", $storico);
$data_estr = "-";
$insert = [];
echo "<pre>";
foreach ($splitter as $key => $value) {
$dati = explode(" ", $value);
if(count($dati)>1) {
$data_estr = trim($dati[0]);
$ruota = $dati[1];
$n1 = $dati[2];
$n2 = $dati[3];
$n3 = $dati[4];
$n4 = $dati[5];
$n5 = $dati[6];
if(isset($insert[$data_estr]) && is_array($insert[$data_estr]) )
$insert[$data_estr] += [ "data_estrazione" => $data_estr, $ruota."1" => $n1, $ruota."2" => $n2, $ruota."3" => $n3, $ruota."4" => $n4, $ruota."5" => $n5 ];
else
$insert[$data_estr] = array("data_estrazione" => $data_estr, $ruota."1" => $n1, $ruota."2" => $n2, $ruota."3" => $n3, $ruota."4" => $n4, $ruota."5" => $n5 );
}
}
print_r($insert);
echo "</pre>";
}
caricaStorico();
?>
output to this code:
Array
(
[2017/05/02] => Array
(
[data_estrazione] => 2017/05/02
[BA1] => 86
[BA2] => 23
[BA3] => 39
[BA4] => 89
[BA5] => 5
[CA1] => 23
[CA2] => 4
[CA3] => 14
[CA4] => 86
[CA5] => 5
)
[2017/05/03] => Array
(
[data_estrazione] => 2017/05/03
[BA1] => 86
[BA2] => 23
[BA3] => 39
[BA4] => 89
[BA5] => 5
[CA1] => 23
[CA2] => 4
[CA3] => 14
[CA4] => 86
[CA5] => 5
)
)
