PHP - How to transpose an array that is from a text file - php

Question

We have made an array from a text file full of numbers separated by commas, each new line is a new part of the array. (we are not allowed to use explode for this)
We are trying to create a transpose_matrix function to 'transpose' the array now.
Using tutorials on the internet, this is what we have come up with so far, but it doesn't work :(
$myfile = fopen("text1.txt", "r") or die("Unable to open file!");
//echo fread($myfile,filesize("text1.txt"));
$file1 = file("text1.txt");
$store1 = array();
for ($a = 0; $a<count($file1); $a++)
{
array_push($store1, $file1[$a]);
}
for ($k = 0; $k<count($store1); $k++)
{
echo "Line $store1[$k] <br/> END <br/>";
}
function transpose($store1) {
$file1 = file("text1.txt");
$store1 = array();
if (count($store1) == 0) // special case: empty matrix
return array();
else if (count($store1) == 1) // special case: row matrix
return array_chunk($store1[0], 1);
function myCallbackMethod() {
var_dump ($store1);
}
array_unshift($store1, NULL); // the original matrix is not modified because it was passed by value
return call_user_func_array('myCallbackMethod',$store1);
}
transpose($store1);
fclose($myfile);
}

Answer 1

Try reading with fscanf().
something like
fscanf($file_link, '%s\n', $temp);
array_push($array, $temp);
should work.
