Im trying to write a php script to read each line of a file, and continue looping until the end of the file is reached, but cannot find out how to detect the end of the file.

Code in vb.net would be:-
        FileOpen(1, "c:\temp.txt", OpenMode.Input)
        While EOF(1) = False
            inputStr = LineInput(1)
        End While

Only code I can really find at the moment, reads the top 3 lines of the file (I know I can repeat it xx times, but the file can be different lengths.

Any help would be appriciated.

Thanks in advance
$myFile = "C:\\phpTest\\testFile.txt";
$fh = fopen($myFile, 'r');
 
$theData = fgets($fh);
echo $theData;
 
$theData = fgets($fh);
echo $theData;
 
$theData = fgets($fh);
echo $theData;

I would use file_get_contents()

Otherwise, use a while($theData = fgets($fh)) loop
// Get the whole file into a single string
$fileContents = file_get_contents("C:\\phpTest\\testFile.txt");
 
// Explode the file contents string by each line
$lines = explode(PHP_EOL, $fileContents); // Replace PHP_EOL with "\r\n" or "\n" or "\r" if you like
 
// Iterate through each line and do what you need with it
foreach ($lines as $line) {
   echo $line;
}

Veonik is right, but fgets solution looks like in the code snippet.
feof() is your friend.
$myFile = "C:\\phpTest\\testFile.txt";
$fh = fopen($myFile, "r");
 
if ( $fh )
{
  while ( !feof($fh) )
  {
    $line = fgets($fh);
  }
  fclose($fh);
}
