But since this sounds like an internal-facing page, you might have control over which browser you use and you might not need to do this step at all. If you want to be super-cautious, just echo 8k of blank spaces at the very beginning (use str_repeat() to do this easily) and then you can start with the normal output. (6) Now the content is pushed to the browser but some browsers buffer the initial chunk of data before they start rendering. (5) If you have any HTTP proxies (very common in corporate networks) between your computer and the web server, you will need to whitelist your script url so the proxy doesn't try to buffer and analyze it. So you'll have to disable all compression and buffers on the web server, at least for your page. And like I said before, compression utilizes a buffer. It is very, very common for web servers to try and compress all content that has a "text" content type like text/html or text/xml, or compress based on file extension being requested or things like that. (4) Once the content makes it back to the web server, the web server itself may have multiple buffers. The configuration here (if you're using FastCGI at all) all depends on your current setup, so ask your system admin if you don't know for sure. This might require a little more advanced system configuration knowledge because you might not want to disable it for every script. If you're running with FastCGI / FPM, then there is a possible buffer there you'll have to disable. (3) Once PHP is done with the content, it passes it back to the web server. I don't recommend disabling this in your actual php.ini because you usually do want it for most of your scripts. Again, you can disable this with ini_set() like we did with output buffering above. Compression works by being able to look at ALL the data and find compressible patterns, so if you have zlib_compression enabled in your PHP config, then PHP will wait for the script to finish executing and then pass all the data to zlib for compression before sending it back to the web server to send to your browser. You can either disable output buffering in your php.ini file or at the top of your script with ini_set("output_buffering", 0) or just use ob_flush() and flush (). (1) The most basic layer is the PHP "output buffer" mentioned by others already. You have to disable EVERY layer of buffering in order to see real-time output from PHP. Some are in PHP and some are in the web server (and in some rare cases you might have an intermediate proxy, too). The main thing to understand is that there are usually several layers of buffering.
