Naming each line in array in for each loop - php

Question

I have multiple arrays, where I want to name each array at the end of the for each loop.
The code php code:
<?php
$csv = array_map("str_getcsv", file("translations/dk.csv"));
foreach ($csv as $line){
if ($line[1] != NULL){
$line[0] = $line[1];
}
print_r($line[0]);
print_r("<br />");
}
fclose($csv);
?>
Example of the arrays.
Array ( [0] => Search and Save [1] => Søg og Spar på Hoteller )
Array ( [0] => Where are you going? [1] => Hvor skal du hen? )
Now the output of line[0] is each time the foreach loop runs naturally with a different value. But I need to name each $line[0] on every loop so I can access them afterwards. How do I do this ?

Answer 1

First of all, you shouldn't use file() to split up the lines; CSV records may span multiple lines.
$f = fopen("translations/dk.csv", 'rt');
$csv = array();
while (($data = fgetcsv($f)) !== false) {
$csv[] = $data;
}
fclose($f);
Second, to select the first column from the array you can use array_column():
$results = array_column($csv, 0);
// "Search and Save", "Where are you going?"]

Maybe you're looking for something like this:
<?php
$csv = array_map("str_getcsv", file("translations/dk.csv"));
$results = array();
foreach ($csv as $k => $line){
if ($line[1] != NULL){
$line[0] = $line[1];
$results[$k] = $line[0];
}
print_r($line[0]);
print_r("<br />");
}
print_r($results);
?>
