Attention

The documentation is incomplete. The Vae Soli! team works hard to make it as exhaustive as possible with tons of useful examples and easy to understand explanations.

On top of that, we have decided to use our own tool to generate the documentation you read. This also takes time to fine-tune. Our goal is have better documentation, easier to read, easier to use, completely integrated with our site.

Even though NOT finalized, you can now link back to our documentation pages as we have decided once and for all about the structure of our documents and where they all reside on our server.

Thank you very much
The Vae Soli! team.

Notes
Note: algorithm

The HTML_IsUTF8() function tries to determine if an HTML code is UTF8 encoded by examining (in sequence):

  1. the http-equiv="content-type"
  2. the meta="charset"
  3. run the mb_detect_encoding() function on the text ($szStr)
Syntax

HTML_IsUTF8( $szStr )

Parameters
NameTypeDescription
$szStr string Input string (typically the HTML code of a web page)
Return

(bool) true if $szStr is UTF-8 encoded; false if not

Example(s)
if ( HTML_IsUTF8( $szText = HTTP_GetURL( $szURL ) ) )
{
    $szText = utf8_decode( $szText );
}
