Solution 1:
You can use stream_get_contents. Simply, stream your text file like tailing. Your client html will make ajax call every minute to your server side script written in php. For example;
PHP: file_read.php
<?phpif (isset($_GET['tail'])) {
session_start();
$handle = fopen('your_txt_file.txt', 'r');// I assume, a.txt is in the same path with file_read.phpif (isset($_SESSION['offset'])) {
$data = stream_get_contents($handle, -1, $_SESSION['offset']);// Second parameter is the size of text you will read on each requestecho nl2br($data);
} else {
fseek($handle, 0, SEEK_END);
$_SESSION['offset'] = ftell($handle);
}
exit();
}
?>HTML:
<!doctype html><htmllang="en"><head><metacharset="UTF-8"><scriptsrc="jquery.min.js"></script><!-- give corrected jquery path --><script>setInterval(function(){get_contents();}, 10000*60);
functionget_contents() {
$.get('file_read.php.php?tail', function(data) {
$('#contents').append(data);
});
}
</script></head><body><divid="contents">Loading...</div></body></html>
