Parse a text file into an array of associative arrays by splitting on semicolons, then commas, then equals signs

Question

I have created this array from a text file by exploading every line by ';'.

How can I set the value before the '=' sign as key and the other one after the '=' sign as value?

Array
(
    [0] => Array
        (
            [0] => title=PHILIPS MIXER H31453
            [1] => gramaj=buc
            [2] => greutate=1
            [3] => prettotal=116.07
            [4] => pretredus=0
            [5] => poza=110.jpg
        )
    [0] => Array
        (
            [0] => titlu=PHILIPS MIXER H31453
            [1] => gramaj=buc
            [2] => greutate=1
            [3] => prettotal=116.07
            [4] => pretredus=0
            [5] => poza=110.jpg
        )
)

The result should be like:

[titlu] => PHILIPS MIXER H31453
[gramaj] => buc
[greutate] => 1
[prettotal] => 116.07
// and so on...

This is where I need it.

function runSql(){
    session_start();
    header('Content-type: text/html;charset=utf8');
    global $outcount;

    $db = $this->pdoconnect();
    $db->setErrorLog(true);

    $files = $_SESSION['sql'];
    $to_process = array_shift($files);
    $get_sql = @file_get_contents($to_process);
    @unlink($to_process);

    $split = explode(";", $get_sql);
    unset($split[count($split) - 1]); // Clear the last empty element

    $final_array = array();
    foreach ($split as $row) {
        $final_array[] = explode(',', $row); // Explode each row by , to each row of final_array
    }
            
    //$stmt = $db->insertBatch('produse', $final_array, true)->getAllLastInsertId();
            
    echo 1;
}

Just do the same thing, explode each item and use the first part as the key and second part as the value

$split       = explode(";", $get_sql);
$final_array = array();

foreach ($split as $row) {
    $arr = explode(',', $row);
    $res = array();

    foreach($arr as $item) {
        $parts = explode("=", $item);
        $res[$parts[0]] = $parts[1];
    }

    $final_array[] = $res;
}

It works just for the firs array, updated my question

That's because all the arrays have the same key, so when you do $arr["title"] in the loop it probably overwrites the value. Try the updated code

If you mutate your 3x delimited text into a format that PHP can natively parse, you can avoid performing so many explosions. Format, parse, transpose, and use. Demo

$txt = 'title=PHILIPS MIXER H31453,gramaj=buc,greutate=1,prettotal=116.07,pretredus=0,poza=110.jpg;title=PHILIPS MIXER H31453,gramaj=buc,greutate=1,prettotal=116.07,pretredus=0,poza=110.jpg;';

$array = parse_ini_string(
    str_replace(
        ['=', ';', ','],
        ['[]=', "\n", "\n"],
        file_get_contents($to_process)
    )
);
    
foreach ($array as $k => $row) {
    foreach ($row as $i => $v) {
        $rows[$i][$k] = $v;
    }
}
var_export($rows);

Output:

array (
  0 => 
  array (
    'title' => 'PHILIPS MIXER H31453',
    'gramaj' => 'buc',
    'greutate' => '1',
    'prettotal' => '116.07',
    'pretredus' => '0',
    'poza' => '110.jpg',
  ),
  1 => 
  array (
    'title' => 'PHILIPS MIXER H31453',
    'gramaj' => 'buc',
    'greutate' => '1',
    'prettotal' => '116.07',
    'pretredus' => '0',
    'poza' => '110.jpg',
  ),
)

There will be many ways to perform this task. Another way is to replace semicolons with newlines and use fscanf() to parse each line -- this has the advantage of being able to explicitly cast parsed numbers into int and float types. See similar tasks at:

Ultimate, despite slightly more effort at write-time, it would be far less painless at read-time to store your data as JSON.
