当php文件写入时捕获

Question

I would like to know if its possible to force PHP to execute as a file rather than being overwritten?

I have set the sendmail -X option for logging which will happily log to a file. When I set it to point to a PHP file it appended to the actual file. Is there anyway (I'm using Ubuntu) to effectively run the file rather than it being written to?

The file currently reads (which I would like to execute):

<?php
$pointer = fopen('php://stdin', 'r');

file_put_contents('/home/www/dev1/log.log',$pointer);
?>

If you are using Bash, you can try process substituion:

sendmail other-args -X >(php your-php-file.php)

This will pass the contents to your PHP file's stdin directly.

However, use stream_copy_to_stream, because if you use stream_get_contents or other one-time functions like that, nothing will be written until the process closes.
