Question

How can I echo a php array to the jquery $.each function?

Here’s what I tried so far in php…

                  $index = 0;

                  while(!feof($file))
                  {
                     $singleLine = fgets($file);
                     $totalLines[$index] = $singleLine;

                     ++$index;
                  }
                  echo $totalLines;

Here’s how I’m reading it back in jquery…

       $.post("sendFile.php",{fileName: sendFileName}, function(data)
       {
              $.each(data, function(index, value)
              {
                        alert(value);
              });
       });

The output is giving me Array…when it should be giving me Test1, Test2, Test3 for each array element…

Use json_encode to encode your data.

echo json_encode($totalLines);

And your php code could simply be written as below: (use file function to read entire file into an array)

echo json_encode(file($file));
// or if need to skip the empty line and new line char
echo json_encode(file($file, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES));
