![]() ![]() sleep() blocks the whole thread it is called in, and under heavier load, it makes servers utterly unresponsive. It's very, very bad practice to use sleep() in a server side script, that is why documentation on working around the pecularities of PHP's buffering (and thread execution) is so sparse. Note: This directive is hardcoded to Off for the CLI SAPI Integer = Enables the buffer and sets its maximum size in bytes. Note: Output buffering can also be controlled via Output Buffering Control On production servers, 4096 bytes is a good setting for performance emitting less packets due to buffered output versus PHP streaming the output You also may see performance benefits if your server is You may be able to send headers and cookies after you've already sent output interesting side-effects depending on your application and web server. Turning on this setting and managing its maximum buffer size can yield some will send that data in chunks of roughly the size you specify. If your application's output exceeds this setting, PHP (excluding headers and cookies) PHP should keep internally before pushing that Output buffering is a mechanism for controlling how much output data Oh and just for the record, this is what my hoster writes about output buffering: Things are not always as they are (simple) explained on php.net and w3schools and a lot of fuzz is behind of it.īut luckily 99% is working as they explain. I have this setting on my hoster: output_buffering = 4096Īnyways thanks everybody for stepping in on this. Same thing, all text is outputted or shown at once at the end. ![]() ![]() $GLOBALS->registerfunction("long Sleep (long dwMillisecods) From kernel32.Hi flydev yes I tried your second code also. USleep alternative for Windows and PHP4: So I get with this snippet wich works fine for me, you get milliseconds precission but the more important, it works for long-run scripts and of course, it does not waste any CPU cycles. Though another solution should be found, and googling a bit I fount a WinAPI function: Sleep. I don't know if network connections go strange, but I know it does not work since you've made more than 2000 - 3000 calls to it, so it's not a reliable solution in 'long life' php scripts, or these are the issues of the microdelay function in my PHP and PHP-GTK applications. The Bernie's microdelay function using fsockopen does not work properly, and the fclose doesn't help much. If you're using Windows then you maybe are in trouble with usleep if you really need to use it. ![]() Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?
