First line missing while reading string using PHP

Question

I am reading a long string coming from an editor using PHP. It misses the first line. Please see the code below.

$separator = "\r\n";
$line = strtok($article, $separator);

while ($line !== false) {
    # do something with $line
    $line = strtok( $separator );
    echo $line;
}

If the text is like -

Line1Line1Line1Line1 Line1Line1Line1
Line2Line2Line2Line2 Line2Line2Line2
Line3Line3Line3 Line3Line3

Then it prints from the second one.

Any help is highly appreciated.

Because you already consumed one line before the loop. $line = strtok($article, $separator); will have the first line. — El_Vanja

Also, that's a quite convoluted workaround for reading a file line-wise. — mario

Maybe something like this could work...

$separator = "\r\n";
$line = strtok($article, $separator);

while ($line !== false) {
    echo $line;
    $line = strtok( $separator );
    
}
