Hi,
few minutes ago I was asked by a friend :
"How can I read the user input in CLI?"
He proposed this :

<?php
print "enter:\n";
$r = fread(STDIN, 100);
print $r;
?>

but....the user has to enter EOF (Ctrl-Z on Windows, Ctrl-D on *nix). This
is not intuitive.
So after some thinking I created this :

<?php
print  "enter:\n";
fscanf($STDIN, "%d\n",$r); //reading a number
print  $r;
?>

I haven't found an example about that issue on the CLI SAPI page.

Thanks,
Andrey

sorry
STDIN instead of $STDIN

Note: there should be an another one with fgets() IMHO.

I completely agree.
fscanf() is for advanced users but one example with fgets() and fscanf() will be better IMHO.

If \r\n was used in the example, would this CLI example work fine on all OS's including macs? (which uses \r)

Ilia fixed the \r issues in the streams layer itself a while ago, so this should work on mac.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"If you want to read single line from stdin, you can use
<?php
$line = trim(fgets(STDIN)); // reads one line from STDIN
fscanf(STDIN, "%d\n", $number); // reads number from STDIN
?>
"
