export variables inside php script

nathan_nz

hi all..
I want to get the environment variables in my php script.

ie php exec('source /pth/to/var/file');

where variable file contains variable list. like export Var1=Value1...

I cant use Var1 inside my script even after sourcing it..

Please tell whether I am going wrong or is there another method for it..

Thanking you

I want to get the environment variables in my php script.

It sounds like the superglobal array $_ENV might be what you are looking for. Read the PHP Manual on Predefined Variables to know more about it.

No.

I dont want ENV variables.
I stored them in a file..
I want to 'source' that file inside php script.
The same we do in Shell scripting

Oh, now I understand. What is the file format?

nathan_nz

Its a normal file.
The content of it is as below..

export var1=value1

laserlight

Its a normal file.

Then use [man]file_get_contents/man.

The content of it is as below..

export var1=value1

Ah, but this means that it is not a "normal" file 😉
It has a file format, namely:
export field=value

If you are willing (and able) to change the format to exclude the "export" word, [man]parse_ini_file/man would make life simple for you. If not, [man]file/man may be what you are looking for.

I got it.

But cant I 'source' the file and use the variable (as $var1) as in shell scripts.
I think that s easier than this string manipulation.
I am new to php. I thought exec() or something like that would fulfill my requirements...
Any Ideas please???

It might, but then depending on external programs or shell commands can make your code unportable.

Is is impossible to get this done???
