UrlGet version 2026-09-11

Questions answered by this extension

I want to use the built in RecipeCheck or Blocklist recipes.

• how do I do this if "allow_url_fopen" is disabled by my webhost?
• how do I do this in preference to "file_get_contents" used internally by PmWiki?
• I want to write a recipe that uses simplexml_load_file

Description

This extension provides a function UrlGet which uses cURL to retrieve the contents of the URL.
The global variable $UrlGetFunction is set to UrlGet using the PmWiki function SDV if it is not already set.

The internal PmWiki variable "$UrlGetFunction" is set to "UrlGet\UrlGet".
UrlGet is a function that uses "cURl"(approve sites) to retrieve the contents of a URL.
Returns the URL contents as a string, or FALSE, the same as "file_get_contents".
Returns error messages in $FmtV['$UrlGetMsg'].

$allowUrlFopen = ini_get('allow_url_fopen') === 1;
if (!$allowUrlFopen) {
    $retVal .= RECIPENAME . ': The PHP runtime setting "allow_url_fopen" is not enabled.' . BR;
}
