PHP Multidimensional array with explode() splits wrong
Get the solution ↓↓↓
I have a file called data.txt with the following inside: (three groups containing each three cars)
"audi,bmw,mercedes#volvo,fiat,seat#peugeot,..."
and so on, you get the idea.
Splitting the "groups" by the # with the php explode() works perfectly fine. However, when I'm trying to split the groups by the komma, it does not work the way I want it to:
For "$tablerow[0][1];" I just get the letter "u"(second letter) instead of "bmw" (second word as intended).
Where is my mistake (Code below)?
The $index_number just counts the number of those groups.
$datafile = fopen("data.txt","r"); <br>
$alldata = fread($datafile,filesize("data.txt")); <br>
$tablerow = explode("#",$alldata); <br>
for ($arrayposition = 0; $arrayposition <= $index_number; ++$arrayposition) { <br>
for ($tablerowindex = 0; $tablerowindex <= 3; ++$tablerowindex) { <br>
$tablecolumn = explode(",",$tablerow[$tablerowindex]); <br>
} <br>
} <br>
echo $tablerow[0][1];
Answer
Solution:
After$tablerow = explode("#",$alldata);$tablerow is an array of comma-separated cars. e.g.$tablerow[0] == 'audi,bmw,mercedes'.
Later you loop over that array and split every element. But you don't touch the$tablerow anymore.$tablerow stays what it is. So$tablerow[0][1] references the second character of the first element, which is "u"
What you probably need is something like
$alldata='audi,bmw,mercedes#volvo,fiat,seat#peugeot';
$table = [];
foreach (explode("#", $alldata) as $carGroup) {
$table[] = explode(",", $carGroup);
}
// $table[0][0] => audi
// $table[0][1] => bmw
Answer
Solution:
It is much easier. Justexplode, loop andexplode creating a new array of rows with an array of columns:
$tablerow = explode("#", $alldata);
foreach($tablerow as $row) {
$result[] = explode(',', $row);
}
Answer
Solution:
You can use #.
str_getcsv.
$alldata = 'audi,bmw,mercedes#volvo,fiat,seat#A,B,C';
$data = array_map('str_getcsv', explode('#', $alldata));
Working example.
