php code which i am trying to change in CF

Question

I am working on something which unfortunately does not have anything in CF, so there are few things which i am trying to do to convert but some functions which i am not sure what is the equivalent of those in Coldfusion, any guidance will be helpful

$nonce = explode(' ', microtime());
$request['nonce'] = $nonce[1] . str_pad(substr($nonce[0], 2, 6), 6, '0');

for the above, to me it seems just a timestamp in ACF , if i am doing wrong please guide, because i am not sure what explode and str_pad is doing here

so my CF equivalent is:

<cfset nonce = createobject("java","java.lang.System").currentTimeMillis() & "000">

what is base64_decode and base64_encode of PHP in ACF

i think binaryencode and binmarydecode but i am not sure

and i tried finding a lot what is http_build_query in PHP as to Coldfusion, but i think its cfhttp but i have no clue

My recommended method for rewriting something in another programming language is to first write it out in whatever language you speak, English, French, whatever. Then use that document as a specification. — Dan Bracuk, Jan 18 '21 at 13:44

I'd suggest you bookmark the main Adobe ColdFusion documentation, as well as the community docs:

If you just Google "base64 encode with ColdFusion", you'll find the related functions.

https://cfdocs.org/tobase64

toBase64(string_or_object [, encoding]) → returns string

https://cfdocs.org/tobinary

toBinary(base64_or_object) → returns binary

You won't find a lot of resources about directly converting from CF to PHP or vice-versa. But if you look up what the actual PHP function DOES, then you're more likely to find the related CF function.

https://www.php.net/manual/en/function.http-build-query.php

http_build_query ( mixed $query_data , string $numeric_prefix = ? , string $arg_separator = ? , int $enc_type = PHP_QUERY_RFC1738 ) : string

Generates a URL-encoded query string from the associative (or indexed) array provided.

This takes the result of a query in PHP and converts it to the query string for a URL.

column1=A&column2=B

I don't think there's a CF function that does exactly that, but you can loop over the columns in the result of a cfquery and create the same output string using the CF function encodeForURL() on the query string parameter values.

Thanks, i know there are some hicups while finding the equivalents in ACF, Another catch is i think my nounce is correct because it seems you did not mentioned it, because i had no clue what the str_pad be in Coldfusion, as per PHP, it seems it is adding padding to the string on the one of the side, left or right — Jhing, Jan 18 '21 at 12:28

There's a third-party function to do that:

/**
 * Converts a structure to a URL query string.
 * 
 * @param struct      Structure of key/value pairs you want converted to URL parameters 
 * @param keyValueDelim      Delimiter for the keys/values.  Default is the equal sign (=). 
 * @param queryStrDelim      Delimiter separating url parameters.  Default is the ampersand (&). 
 * @return Returns a string.

 */
function StructToQueryString(struct) {
  var qstr = "";
  var delim1 = "=";
  var delim2 = "&";

  switch (ArrayLen(Arguments)) {
    case "3":
      delim2 = Arguments[3];
    case "2":
      delim1 = Arguments[2];
  }
    
  for (key in struct) {
    qstr = ListAppend(qstr, URLEncodedFormat(LCase(key)) & delim1 & URLEncodedFormat(struct[key]), delim2);
  }
  return qstr;
}

A little warning, this function lower-cases each query parameter name. You can disable that by removing "LCase()". — Harry, Aug 16 '22 at 12:21
