问题描述

尝试使用所有可能的参数（例如-d和完整路径等）执行它。没有错误。当运行另一个命令时，一切正常，从CMD运行作曲器时，一切也正常。已经尝试过exec，system，shell_exec等。

Trying to execute it with all possible params, such as -d and full path etc.. No errors. When running another commands, all is ok, when running composer from CMD, all is ok too. Have tried exec, system, shell_exec etc.. What it could be?

echo system（'php composer.phar install'）;

echo system('php composer.phar install');

也尝试输出错误流：

system('php composer.phar install 2>&1');
