Missing streams - Cannot read from STDIN ??? #1065
Comments
|
Now I tried this: <?php
$input = fopen('php://stdin', 'r');
$output = fopen('php://stdout', 'w');
stream_set_blocking($input, false);
echo "OUTPUT:".PHP_EOL;
fwrite($output, 'HELLO');
$contents = '';
// Use stream_select to check for input availability
$read = [$input];
$write = null;
$except = null;
$timeout = 1;
//$ready = stream_select($read, $write, $except, $timeout); // This line is uncompilable ????
$ready = 1;
if ($ready > 0) {
// Input is available, read it
while (!feof($input)) {
$line = fgets($input);
if ($line === false) {
break;
}
$contents.= $line;
}
} else {
echo "No input available.\n";
}
echo "Input: ".$contents.PHP_EOL;According to the funtions file, php://stdin and php://stdout are defined but while the code above compiles the output is: henrik@HSLAPTOP-ASUS:/tmp/sreq2$ echo "HELLO" | ./test2

Input:So how do you read from php://stdin and write to php://stdout using KPHP ? Please help ! |

HELLOSo how exactly do you read from STDIN using KPHP ? I checked the C++ source and php://stdin is defined as a Stream ? Please help ! |

Next I tried using php://input The output was then # echo "FOO" | ./testthe output is: [60444][2024-08-15 10:58:36.405808 limits.cpp 124] failed to set rlimit for core dump size.

The php streams:
php://memory
php://temp
php://input
php://output
are all missing !
I tried to compile this simple script:
I compiles fine with:
kphp test2.php --mode cli --composer-root $(pwd) -o ./test2But when run output is:
Also:
stream_copy_to_stream() is missing
stream_get_meta_data() is missing
stream_get_contents() is missing
Can the missing streams ('php://temp', 'php://memory', 'php://input' and 'php://output') be added soon ?
I just spent a couple of days making a PSR-7 HTTP Message implementation to use with KPHP and it compiles fine but does not work due to the missing streams ???
Please prioritize this !
