Populate a 2d array with qualifying data from a multi-line txt file containing comma-separated values

Question

Below script is shown search string in a text file, my text file has contents like:

60, 1, 1, 188, pdgje5566

60, 1, 1, 188, pdgje5565

if(!empty($extTxId)){
$searchfor = $extTxId;

$matches = array();

$handle = @fopen($file, "r");
if ($handle)
{
    while (!feof($handle))
    {
        $buffer = fgets($handle);
        if(strpos($buffer, $searchfor) !== FALSE)
            $matches[] = $buffer;
    }
    fclose($handle);
}

print_r($matches);

it output as

Array ( [0] => 60, 1, 1, 188, ppje5566 )

However, I want to explode the data which is separate by comma(,) and store into variable, is that anyway to do it?

Answer 1

Since you have spaces between each comma, you can trim each element.

// Iterate through each item int the array (you can do $matches[0] if you just want the first)
foreach ($matches as $match)
{
     $output_array = array_map('trim',explode(',',$match));

     print_r($output_array);
}

Output:

Array
(
    [0] => 60
    [1] => 1
    [2] => 1
    [3] => 188
    [4] => pdgje5565
)
