I tested that the access_by_php directive was not executed.Need to research in depth.

@rryqszq4 I wait u

The 'return' directive is in the 'rewrite' phase, earlier than the 'access' phase.

Try the following example：

...

set $sel 0;
location = / {
    access_by_php '
        $x = 1; 
        ngx_var::set("sel", $x);
    '; 
    content_by_php '
        echo ngx_var::get("sel");
    ';
}

...

I know it works but I want to change a variable in nginx.

for example

`set $sel 0;
location = / {
    access_by_php '
        $x = 1; 
        ngx_var::set("sel", $x);
    '; 
    content_by_php '
        echo ngx_var::get("sel");
    ';
    if ($sel = 1) {
     #I want to make transactions here
    }

}`

@rryqszq4 Isn't it possible ?

[rryqszq4]

@fatalafitili
For example about what transactions?

[fatalafitili]

@rryqszq4
My only goal is to change the value of a nginx variable with php,
I can use that variable in all fields, usually if parameter

[rryqszq4]

@fatalafitili
I think the ‘rewrite_by_php’ directive should be used, but there are some bugs.

Okay, buddy, I'm gonna do it for now, but I'm waiting for an update. :)

Change access_by_php to rewrite_by_php, I found it is ok.

...

set $sel 0;
location = / {
    rewrite_by_php '
        $x = 1; 
        ngx_var::set("sel", $x);
    '; 
    return 200 $sel;
}
