output-buffering

I'm trying to implement a simple Http Response class that implements Http Streaming (or Chunked-Encoding). For this to be possible, I need to set output_buffering = Off in the php.ini, and flush the output at certain intervals. PHP does a good job of this automatically - except for the actual flushing mechanism. I've gotten it to work, but I'm not sure if it's overboard. I want to know how to flush each level of output buffering at once, without calling a billion functions (I'm not sure which ones are redundant on which environments / in which scenarios). while (ob_get_level()) { ob_end_flush(

Well, now that I've gotten a bit further into it, I realize that this is a stupid question, and wrong. Turns out that the author of the legacy code I maintain was hi-jacking the error log to a different file with a php_init statement. The hi-jacking occurred at the same time as the output buffering was turned on, making it appear as though output buffering was throwing away my error messages. So, Mr. Moderator, feel free to delete this. Thanks to those who answered in good faith. Given the following PHP script: <?php error_log('test'); ob_start(); error_log('test2'); ob_end_flush(); ?> I get

For some reason my XAMPP server is buffering the output of my PHP. I want it to spit it out as it goes. Anyone any ideas which settings I need to change to achieve this? Check out ob_end_flush() , the manual's chapter on output control - specifically the php.ini settings . Of course if you're just getting a blank page, check your error reporting settings - it's very possible an error halts the script, and with error reporting off you see nothing. XAMPP appears to set output_buffering to 4096 by default. (So content is served in 4K chunks - a possible performance benefit. Although this can lead

In PHP, I want to read a file into a variable and process the PHP in the file at the same time without using output buffering. Is this possible? Essentially I want to be able to accomplish this without using ob_start() : <?php ob_start(); include 'myfile.php'; $xhtml = ob_get_clean(); ?> Is this possible in PHP? Update: I want to do some more complex things within an output callback (where output buffering is not allowed). A little known feature of PHP is being able to treat an included/required file like a function call, with a return value. For example: // myinclude.php $value = 'foo';

I mean... Let's that we just make an AJAX request and inser the result inside a div#result.. In the backend the script use ob_flush() to send the header but not terminate the request until it's terminated (with exit or ob_flush_end ) The content will be loaded into the #result only when the request terminate ( exit or ob_flush_end ) or it'll be loaded every time the script send the header by ob_flush ? Update: I'll use jQuery load() to make the request & PHP to answer it Yes, content will be returned, but the XHR object's readyState will not be set to 4, so if you are relying on that to update

Title is self-explanatory. I have a good bit of experience with PHP, but I am not sure how the header function works between ob_start() and ob_end_clean() . Consider this: ob_start(); echo "Some content"; header('X-Example-Header: foo'); echo "Some more content"; $output = ob_get_contents(); ob_end_clean(); echo $output; Does the header function ignore the output buffering, and thus all headers get sent before the content because it is echo ed after the header call? Or does it work some other way? The header() does indeed ignore output buffering. Part of the reason to use output buffering is

I am trying to continue a PHP Script after the page/connection is closed. Users will POLL the script in every 1 hour, I want to return some json output and want to continue the script in the background. I am using a shared host and I cannot use cron job. Here is what I've tried. ob_start(); ignore_user_abort(); echo "JSON_OUTPUT GOES HERE"; $ob_length = ob_get_length(); header("Content-Type : text/plain",TRUE); header("Content-Length : $ob_length",TRUE); header("Connection : Close",TRUE); flush(); ob_flush(); ob_end_flush(); sleep(3); echo "You cant see me.."; exit(); I am using Codeigniter
