Recursive functions

Do not use “call to self” by name inside recursive functions. Use variable functions instead:

function test($i) {
   static $__this = __FUNCTION__;
   if($i > 5) {
       echo $i. "\n";
       $__this($i-1);
   }
}

@@Stackoverflow_logo@@ Can I make a PHP function “private” in a script?

$func = function () { ... }. Then you can use it as $func();.

CA certificates for SSL

Certificates are available from: https://curl.se/docs/caextract.html

Run this script in elevated state (CMD - not you). The script uses CURL @@Curl_icon@@ to download the certificates.

:getCacert
    CD "%ProgramFiles%\php"
    SET CACERTDIR="%ProgramFiles%\php\cacert"
    :: Create dir if not exist

    CD %CACERTDIR% 2>NUL || (ECHO %CACERTDIR% & MKDIR %CACERTDIR% & CD %CACERTDIR%)
    curl --etag-compare etag.txt --etag-save etag.txt --remote-name https://curl.se/ca/cacert.pem
    DIR
GOTO :EOF

Modify php.ini to enable the SSL:

[openssl]
; The location of a Certificate Authority (CA) file on the local filesystem
; to use when verifying the identity of SSL/TLS peers. Most users should
; not specify a value for this directive as PHP will attempt to use the
; OS-managed cert stores in its absence. If specified, this value may still
; be overridden on a per-stream basis via the "cafile" SSL stream context
; option.
