Fatal error when phpinfo is disabled #88
Description
If you put the phpinfo function in disabled_functions and try to use class Process with php8.0, it will throw the next error
PHP Fatal error: Uncaught Error: Call to undefined function phpinfo() in .../vendor/react/child-process/src/Process.php:373
There is the next code where it throw error attempting to call phpinfo function https://github.com/reactphp/child-process/blob/master/src/Process.php#L435
/**
* Return whether PHP has been compiled with the '--enable-sigchild' option.
*
* @see \Symfony\Component\Process\Process::isSigchildEnabled()
* @return bool
*/
public static final function isSigchildEnabled()
{
if (null !== self::$sigchild) {
return self::$sigchild;
}
\ob_start();
\phpinfo(\INFO_GENERAL);
return self::$sigchild = \false !== \strpos(\ob_get_clean(), '--enable-sigchild');
}
In the comments to the method there is a reference to a similar method from the Symfony class, where the disabled phpinfo state is provided https://github.com/symfony/symfony/blob/5.4/src/Symfony/Component/Process/Process.php#L1377
protected function isSigchildEnabled()
{
if (null !== self::$sigchild) {
return self::$sigchild;
}
if (!\function_exists('phpinfo')) {
return self::$sigchild = false;
}
ob_start();
phpinfo(\INFO_GENERAL);
return self::$sigchild = false !== strpos(ob_get_clean(), '--enable-sigchild');
}
Since phpinfo is disabled for security purposes in my case, is it possible to add this behavior?
