PHP: Getting values from array index

Question

I have file with datas. Every line has name of author/authors..it looks like this:

"Giacometti, Jasminka"; "Mazor Jolic, Slavica"; "Josic, Djuro";
"Hoffmeister, Karin M"; "Grozovsky, Renata"; "Jurak Begonja, Antonija"; "Hartwig, John H";
"Jakopovic, Boris"; "Kraljevic Pavelic, Sandra"; "BelScak-Cvitanovic, Ana"; "Harej, Anja"; "Jakopovich, Ivan";

For example, for the first row:

"Giacometti, Jasminka"; "Mazor Jolic, Slavica"; "Josic, Djuro";

I need to get this and write it in another file:

"Giacometti, Jasminka"; "Mazor Jolic, Slavica";1
"Giacometti, Jasminka"; "Josic, Djuro";1
"Mazor Jolic, Slavica"; "Josic, Djuro";1

How can I do it in php? I tried with getting every line in the array, but then I don't know how to split datas from that row.

$handle = @fopen("datas.txt", "r");
$listA = array();
if ($handle) {
    while (($buffer = fgets($handle, 4096)) !== false) {
        $listA[] = $buffer; 
}

Thank you.

First read the content content from the file that contains the data as full one complete string and then explode that string with end of line character, so each array element will now contain a row of data:

$data = file_get_contents("data.txt"); //data.txt is the file that contains rows of data

$authArr = explode(PHP_EOL, $data ); //this array contains all the rows in it

You can now use this $authArr to write to another file by appending an new line character to the each row i.e each element of array that you will write to the file.

Yes, but I still don't understand how to split datas for example in `$authArr[5]`. – xKRgirl01 Nov 03 '15 at 16:52
use foreach () loop to loop through `$authArr` array – Sourabh Kumar Sharma Nov 03 '15 at 16:53
Thanks, I did it a little bit different, but this helped a lot. `$newElement= explode(";", $authArr[5]);` – xKRgirl01 Nov 03 '15 at 17:16

foreach ( $$listA as $key)
    {
    $part = explode(";",$key); 
    }

Split the string by using ; as separater. You have to discard the last element of the $part array as it will be ''.

Here you have only three elements in array. So you don't require loops for permute. If you have more numbers, use permutations by loop.

I'm not sure exactly what you want to do with the authors, but this will separate each line into an array of authors;

<?php

$source_string = file_get_contents('source.txt');   // Load the source file.
$source_array = explode(PHP_EOL, $source_string);   // Create an array of one element per line.

// Iterate over the source array.
foreach($source_array as $line) {
  $trimmed = rtrim($line, ';');                     // Trim the semicolon from the end of the line.
  $array_of_authors = explode('; ', $trimmed);      // Explode the line into an array of one element per author.
  $output = print_r($array_of_authors, true);
  echo "<div>Line: {$line}</div>";
  echo "<xmp>{$output}</xmp>";
}

?>

The output produced by the above starts like this;

Line: "Giacometti, Jasminka"; "Mazor Jolic, Slavica"; "Josic, Djuro";

Array
(
    [0] => "Giacometti, Jasminka"
    [1] => "Mazor Jolic, Slavica"
    [2] => "Josic, Djuro"
)
