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);

}
