php - How to set $PATH for php exec or shell_exec

Question

I have set the PATH to run ant and it is working on putty but on php exec it is returning sh ant command not found i have tried to set PATH by export PATH=/usr/ant/bin

Answer 1

在执行之前调用 putenv：

putenv('PATH=/usr/ant/bin');

Answer 2

环境变量是在用户会话的上下文中设置的。如果你想为 PHP 用户设置变量，你应该检查运行 apache 的用户（通常是 apache），并添加

export PATH=/usr/ant/bin

至

/home/apache/.bashrc

apache以便为用户启动的每个会话设置路径。
