How is the upload progress bar implemented? What is the principle?

If we can read the size of this temporary file, we will know the upload progress. The php apc module can implement this function.

1. install the apc module

: Http://pecl.php.net/package/apc

tar zxvf APC-3.1.8.tgzcd APC-3.1.8//usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-configmake && make install

2. modify php. ini

extension = apc.soapc.rfc1867 = 1apc.max_file_size = 200Mupload_max_filesize = 1000Mpost_max_size = 1000Mmax_execution_time = 600max_input_time = 600memory_limit = 128M

After modification, restart apache or other services.
