Question

I am new to PHP so this may be a simple fix.
I have a text file named textt.txt that looks like this:

South East asia,2222,code1
winter break,3333,code2

My PHP code looks like this:

<?php       
$x = file_get_contents('textt.txt');
        $y = explode("\r\n", $x);
        $z = $y[0];
    echo $z;
?>

The outcome of this is:

South East asia,2222,code1

I would like it to return only:

South East Asia.

How can I make this happen?

Answer 1

explode() again on the comma. Your first call to explode() splits the string by lines, each containing a comma-separated string.

<?php       
$x = file_get_contents('textt.txt');
        $y = explode("\r\n", $x);

        // $y[0] now contains the first line "South East asia,2222,code1"
        // explode() that on ","
        $parts = explode(",", $y[0]);

        // And retrieve the first array element
        $z = $parts[0];
    echo $z;
?>
