其他时间，我遇到了与您相同的问题.如果在终端上执行同一行，则结果是相同的，因此这不是php问题，而是shell问题:

I've come across the same problem as you with read other times. If you execute the same line on the terminal, the result is the same, so this is not a php issue, but a shell issue:

$ echo 'Foo' | read -p 'Enter your name : ' x; echo "Your name is : $x"
Your name is : 

如果将read包裹在while .. do .. done内，那么它们都可以完美运行:

If you wrap the read inside a while .. do .. done, then it all works perfectly:

$ echo 'Foo' | while read -p 'Enter your name : ' x; do echo "Your name is : $x" ; done
Your name is : Foo

我不知道为什么会这样.

I don't know why this happens though.

此外，您可以尝试使用 proc_open 和类似的方法，您将获得对输入/输出流，但是我不知道它们是否可以解决read问题.

Also you can try using proc_open and similar, and you'll get more control of the input/output streams, but I don't know whether they will work with the read issue.
