My script: 

<?php //header("refresh: 7;"); include 'theme.php'; ceklogin(); css(); echo '<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.1.min.js"></script> <script> $(document).ready( function() { setInterval(function() { var randomnumber = Math.floor(Math.random() * 100); $("#show").text( "I am getting refreshed every 3 seconds..! Random Number ==> " + randomnumber); }, 3000); }); </script>'; exec('/www/openvpn_wget_status.sh'); echo '<br>'; echo file_get_contents( "/www/openvpn_status.txt" ); echo '<div id="show">'; //include 'wget.log'; //echo "<br><textarea name=\"text-info\" id=\"scores\" rows=\"30\" cols=\"90\" readonly style=\"font-family: Arial;font-size: 7pt;\" >"; //$datalines = file ("wget.log"); //foreach ($datalines as $zz) { //echo $zz; } echo '</div>'; //echo "</textarea><br></div>"; echo '<script type="text/javascript"> var textarea = document.getElementById("scores"); textarea.scrollTop = textarea.scrollHeight; </script>'; foot(); echo ' </div> </body> </div> </html>'; ?>

it works perfectly but what if I want the variable from a log file in my webserver, let's say the name of the log file is wget.log and I want to refresh it every 3 seconds since wget.log keeps changing as I run wget to download files?

  • Don't you need ajax for that? Commented Jan 9, 2015 at 11:37
  • I don't know but it already works fine Commented Jan 9, 2015 at 11:38
  • You need to call ajax and read file from server, echo it using php and print on browser using javascript. Make ajax every 3 seconds. Commented Jan 9, 2015 at 11:39

Script to read file (readFile.php)

<?php //in this script, read any file(or do something else) //whatever you output, it will be processed in ajax request from below script echo "<pre>".file_get_contents( "/www/openvpn_status.txt" )."</pre>"; //used <pre> to keep linebreaks in file. ?>

HTML (another file)

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.1.min.js"></script> <script> $(document).ready( function() { setInterval(function() { $("#show").load("readFile.php"); //it will make ajax call to readFile.php and get output from that script and load to #show div }, 3000); }); </script> <div id="show"> This will be refreshed every 3 seconds. </div>

Wow. Never seen or used that type of ajax call ever. What request type does it use? POST or GET?
@Ravi Dhoriya my log file consists of line breaks and the line breaks are ignored once it's loaded on my webpage, how do I keep the line breaks?
@KrisztiánDudás lol on you. You should have look at this. It uses GET btw
@hillz then print it inside <pre></pre>.
Use the <pre> tag if you want to keep the formatting (linebreaks)
