我可以从命令行运行curl但不能从shell exec调用

Question

I want to use shell_exec to run curl and get the response. The problem is that my shell exec command doesn't work when I run curl, it works fine when I run curl in cmd or cygwin. I'm using laravel 5.6 with php 7.2

I can run:

shell_exec("ping domain.com");

It return response like it has used to.

But I can't run:

shell_exec("curl some thing here");

It gives me null when I use dd() or blank when I print_r().

• My curl version 7.61 windows 10 64bit, open ssl 1.1.0i
• Already set path system variable on environment

I know I can use guzzle, but I am just wondering why it doesn't work.

Consider using PHP Curl (IT's necessary to enable PHP curl extension). It's a safer way - You dont need to access shell + on many shared hostings, it's disabled - and also works natively under Windows.

The problem you are fighting off is caused probably by missing PATH. That's why it works in cygwin, not under native shell. Note that PHP execs in native shell.
