Composer.phar 不想由 PHP 脚本中的 shell_exec 运行。 为什么？

Question

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');

Answer 1

Try outputting the error stream as well:

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

It might give you more of a hint as to what is going wrong.

Answer 2

Try this

$path = 'path where, composer.phar and composer.json exists';

var_dump(shell_exec("
  cd $path;
  export COMPOSER_HOME=$path./.config/composer;
  php $path/composer.phar show -i 2>&1"));
