Sure, here's a test script, the output from it, and a few words on the email I
receive:
<?php
$descriptorspec = array(
0 => array("pipe", "r"),
1 => array("pipe", "w"),
2 => array("file", "/tmp/error-output.txt", "a")
);
$text = "";
for ($i=0; $i<10240; $i++) $text.="1";
$text.="END\n";
$doccmd = "/usr/bin/qmail-inject";
$res = proc_open ($doccmd, $descriptorspec, $pipes);
fwrite ($pipes[0], "TO: somemailaddress@some.host\n\n");
echo fwrite ($pipes[0], $text)."\n";
echo fwrite ($pipes[0], $text)."\n";
fclose ($pipes[0]);
?>
The output is:
10244
6109
Now, that's not counting the first TO: plus two \n's. Altogether it always
sums up to 16384 bytes.
In the email I receive, it honestly shows exactly the amount of data
fwrite() claimed to have written, and not a symbol more.
Any ideas?
