Question

$$I have a bunch fo text files I’d like to eventually explode into arrays, but since the amount of text files is dynamically chosen via user input, I can’t just initialize them one-by-one and instead am opting for a for loop.

For the sake of example, three text files I have contain the following (excuse the \n, imagine it’s a line break):

file1.txt = 1 \n 2 \n 3

file2.txt = 6 \n 2 \n 7

file3.txt = 9 \n 1 \n 9

The code I attempted:

<?php
    for ($i = 1; $i <= 3; $i++) {
        list($line1[$i], $line2[$i], $line3[$i]) = file("public_html/texts/file".$i.".txt");
?>

This obviously doesn’t work, but I’m not sure why. In the end, the result should be:

$line1[1] = 1
$line2[1] = 2
$line3[1] = 3
$line1[2] = 6
$line2[2] = 2
$line3[2] = 7
$line1[3] = 9
$line2[3] = 1
$line3[3] = 9

How do I go about doing this?

edit; fixed typo.

Answer 1

for($i = 1; $i <= 3; $i++) {

    $lines = file('public_html/texts/file' . $i . '.txt');

    $line1[] = $lines[0];
    $line2[] = $lines[1];
    $line3[] = $lines[2];
}
