output-buffering

问题 What is the syntax for setting output_buffering to off in .htaccess? Provide a complete .htaccess file content please? 回答1: This is isn't really a hard thing to find. Anyway, you need to make sure you have PHP running as an apache module for this to work in .htaccess . http://php.net/manual/en/configuration.changes.php <IfModule mod_php5.c> php_value output_buffering Off </IfModule> 来源： https://stackoverflow.com/questions/21561829/syntax-for-setting-output-buffering-in-htaccess-php-5

问题 Output buffering in PHP is fun. It simplifies many things. I use ob_start() at the top of the script and ob_get_clean() (or any other function) at the bottom. Between those two calls is it possible to call those functions again, without interfering the parent calls. Is this type of code valid ? (it works fine, but...) Is this a good habit ? <?php ob_start(); //NOTICE !!! echo '<p>echos of the top of the script</p>'; echo GetSomeOtherData(true); echo '<p>echos after GetSomeOtherData()</p>';

问题 i have a site, where i buffer some output with ob_start(); ... and it worked fine until today i updated my debian from an older php5.3 to the latest php5.3.3-7 +squeeze8 Now i sometimes have something in the output buffer before i call it the first time please don't answer things like "header must be called before any output is sent." (I know, I work a lot with output buffers) when i set an extra ob_get_clean(); at the very first line of my script, it works <? ob_get_clean(); it seems, like

问题 To emphasize, the problem is real time read instead of non-blocking read . It has been asked before, e.g. subprocess.Popen.stdout - reading stdout in real-time (again). But no satisfactory solution has been proposed. As an example, the following code tries to simulate the python shell. import subprocess p = subprocess.Popen(['python'], stdin=subprocess.PIPE, stdout=subprocess.PIPE) while True: line = input('>>> ') p.stdin.write(line.encode()) print('>>> ', p.stdout.read().decode()) However,

问题 I'm trying to implement full page static caching in my Zend Framework application. Using the Static backend coupled with the Capture frontend, whole pages can be cached, and served by a .htaccess redirect in the future, until the cache is deleted/regenerated. For reference, I've been using the section on Zend_Cache_Backend_Static in the manual, and also some further information provided by the class author. As per the example, I have configured the directories for the cache (static HTML files

问题 I hired someone to write an API for me in PHP and MySQL and now have to maintain it myself. I don't know php as well as other languages. I noticed at the start of most of the php files they have: ob_start(); I understand that this opens a new output buffer. The thing is that they never flush the buffer. The code had been working fine but I've had a lot of optimization issues, slow server responses, etc. How is it that they don't have to flush the buffer but the response is still returning? An

问题 I have this code: set_time_limit(0); header("Cache-Control: no-cache, must-revalidate"); header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); ob_flush(); flush(); $start = time(); $secs = time() - $start; while ($secs <= 300) { echo "this script has been running for $secs seconds.\n"; ob_flush(); flush(); sleep(1); } What I'd like to do when I view this page, is to see in real time how long the script has been running, like this: Script has been running 1 seconds. Script has been running 2

问题 when trying to log-in at this site (user:polopolo,pass:samara) the result is a blank page. I know that the problem is with the sending of headers and the ouput_buffering in the php.ini file. I had the same problem on another host but the problem was fixed when I changed output_buffering= On . It doesn't work on the current host and I wonder why? Any suggestions? -the phpinfo of the current site. Edit: Problem solved. I reverse-engineered the code and found some additional spaces after the php

问题 What are the methods to turn on output buffering either within a PHP script or using and htaccess file? I use the following method in an htaccess file in the root of my application: php_value output_buffering On php_value output_handler mb_output_handler On one of my shared hosting accounts (linux hosting with PHP 5.2.x), the above yields a blank page. Tech support says they can't turn it on in the php.ini file but I can turn it on in my script... ob_start() and ob_end_flush() also yields the

问题 So, I'm looking for something more efficient than this: <?php ob_start(); include 'test.php'; $content = ob_get_contents(); file_put_contents('test.html', $content); echo $content; ?> The problems with the above: Client doesn't receive anything until the entire page is rendered File might be enormous, so I'd rather not have the whole thing in memory Any suggestions? 回答1: Interesting problem; don't think I've tried to solve this before. I'm thinking you'll need to have a second request going
