Description Unix supports the principle of piping, which allows processes to send data to other processes A simple example of piping is the following. ps l | head This command, when run on a Unix-like machine
这样我们可以测量内存的占用情况: // from piping-files-1.php file_put_contents( "piping-files-1.txt",file_get_contents 当为更大的文件时,就捉襟见肘了… 让我们尝试用流(管道)来传送一个文件到另一个: // from piping-files-2.php $handle1=fopen("shakespeare.txt", "r"); $handle2=fopen("piping-files-2.txt","w"); stream_copy_to_stream($handle1,$handle2); fclose($handle1 我们可以参照下边的代码来实现它: // from piping-files-3.php file_put_contents( "piping-files-3.jpeg",file_get_contents /rick.jpg","r" ); $handle2=fopen( "piping-files-4.jpeg","w" ); // ...or write this straight to stdout
精美礼品等你拿!

Just like we can compose powerful linux commands by piping other smaller Linux commands, we can do exactly the magic line that you need to remember: readableSrc.pipe(writableDest) In this simple line, we’re piping In fact, if we’re piping into a duplex stream, we can chain pipe calls just like we do in Linux: readableSrc We’re basically pushing all the data in the stream before piping it to process.stdout. We’re piping a readable stream for that file into the zlib built-in transform stream and then into a
