copied!<p>I can't tell if this is going to help with your problem since buffering problems can happen even if not using gzip (zlib).</p> <p><strong>Firstly</strong> it may be that apache has deflate module (mod_deflate or mod_gzip) loaded:<br> You can try to disable it for current script like this:</p> <pre><code>apache_setenv('no-gzip', 1); </code></pre> <p><strong>Secondly</strong> it may be that browser is using internal buffer for response (around 1kB is common for IE, newer Firefox and WebKit browsers, but some browsers may have more or less).<br> That could be solved by echoing at least 1kb of blanks like this example:</p> <pre><code>echo str_repeat(' ', 1024); </code></pre> <p>Note that when using zlib, echoing 1kb of blanks (uncompressed) and flushing will not trigger these browsers to parse and render any content until ~1kb of compressed data is received.</p> <p><strong>Thirdly</strong>, if using sessions (either explicit in script or via php.ini <code>session.auto_start</code>) you need to close the session in order for output to be sent:</p> <pre><code>session_write_close(); </code></pre> <p>I assume your problem is with browser buffer and zlib. You may need to create more than 1kb of compressed data for browser to render it.</p> <p>-- I had tried myself to create flushing with zlib and believe me that is a lots of text to render just for the browser to start processing, at the end i had to echo an image file (which is already compressed) in order for it to work.</p> <pre><code>ini_set('output_buffering', 'On'); //ini_set('implicit_flush', 'On'); ini_set('zlib.output_compression', 'On'); // by default 4kB //ini_set('zlib.output_compression_level', 1); echo "head...wait 3 secs</br>\n"; echo str_repeat("\n ", 500); // this is enought to work fine without zlib echo '<span style="display:none">'; readfile('path/to/an/image/file.png'); // around 8kB (4kB should be enough) echo '</span>'; ob_flush(); flush(); sleep(3); echo 'bar'; </code></pre>
