hello,
I have problem using proc_open in phar file.
here is sample code
<?php
$p = new Phar('test.phar', FilesystemIterator::CURRENT_AS_FILEINFO |
FilesystemIterator::KEY_AS_FILENAME);
$p->startBuffering();
$stub = <<<STR
#!/usr/bin/env php
<?php
Phar::mapPhar();
include "phar://test.phar/parent.php";
__HALT_COMPILER();
STR;
$p->setStub($stub);
$parent = <<<STR
<?php
\$descriptorspec = array(
0 => array("pipe", "r"),
1 => array("pipe", "w"),
2 => array("pipe", "w")
);
\$path = realpath(__DIR__ . '/child.php');
\$process = proc_open('php ' . \$path, \$descriptorspec, \$pipes);
if (is_resource(\$process)) {
fclose(\$pipes[0]);
\$stdout = stream_get_contents(\$pipes[1]);
fclose(\$pipes[1]);
fclose(\$pipes[2]);
\$return_value = proc_close(\$process);
var_dump(\$stdout);
var_dump(\$return_value);
}
STR;
$p['parent.php'] = $parent;
$child = <<<STR
<?php
file_put_contents(sys_get_temp_dir() . '/child', "child");
echo "child";
STR;
$p['child.php'] = $child;
$p->stopBuffering();
I expect /tmp/child file is created by child.php and 1 is set to $stdout as
status code.
but actually child.php seems not to be executed and I get 0 as exit code.
as long as reading php-src and debugging, I find php tries to execl 'php
phar://test.phar/child.php' at here
https://github.com/php/php-src/blob/0ca4358ade18c3839414580da35660c6e9be08d5/ext/standard/proc_open.c#L842
of course it shouldn't work because php cannot execute phar://...
independently.
so does proc_open in phar never work?
I'm not sure although I find some evidences. I cannot believe no one has
not tried to use proc_open in phar until now...
according to git history, this code has not been changed at least 2 years.
is my understanding correct? if so, is there any workaround?
