问题 I\'ve tried several attempts at getting my flush and ob_flush to work.

The script wants to wait until it is completly done until it echos output. Here is the script I have so far ob_start(); //Login User echo \'Logging in to user<br>\'; ob_flush(); flush(); $ch = curl_init(\"http://www.mysite.com/login/\"); curl_setopt($ch,

For example: ob_start(); echo("Hello there!"); //would normally get printed to the screen/output to browser $output = ob_get_contents(); ob_end_clean(); There are two other functions you

问题 I found this in the Python documentation for File Objects: flush() does not necessarily write the file’s data to disk. Use flush() followed by os.fsync() to ensure this behavior. So my question is: what exactly is Python\'s flush doing? I thought that it forces to write data to the disk, but now I see that it doesn\'t. Why? 回答1: There's typically two levels of buffering involved: Internal buffers Operating system buffers The internal buffers are buffers created by the runtime/library/language

问题 What is output buffering and why is one using it in PHP? 回答1: Output Buffering for Web Developers, a Beginner’s Guide: Without output buffering (the default), your HTML is sent to the browser in pieces as PHP processes through your script. With output buffering, your HTML is stored in a variable and sent to the browser as one piece at the end of your script.
