php - 在 php 中处理大型压缩文件

Question

我正在尝试在我的服务器中一次压缩许多图像。压缩文件的大小范围为 250MB-750MB 我使用的是 pclzip 库。

我正在使用共享主机，因此最大执行时间和内存限制是有限的。我怎么解决这个问题？或请告诉我任何替代解决方案。

谢谢

Have you tried using set_time_limit ( int $seconds ) within your script?

Excuse the pseudo code but something like this

initialise the zip class

foreach ( files in the directory as $idx => $name) {
    add $name to the zip file;

    // every 10 files zipped, reset the max_execution_time
    if ( $idx > 0 && $idx % 10 == 0 ) {
        set_time_limit ( 30 );
    }
}

This should keep resetting the max_execution_time to 30 seconds every 10 files you zip.

Maybe 10 is a little small a number but you get the idea.

Alternatively you could try setting the max_execution_time to 0 like so, just once at the top of this script.

set_time_limit( 0 );
