autoloader, but there are some cases where you will need to change
|
||||
your own code to accomodate HTML Purifier. These are those cases:
|
||||
|
||||
PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload
|
||||
Because spl_autoload_register() doesn't exist in early versions
|
||||
of PHP 5, HTML Purifier has no way of adding itself to the autoload
|
||||
stack. Modify your __autoload function to test
|
||||
HTMLPurifier_Bootstrap::autoload($class)
|
||||
|
||||
For example, suppose your autoload function looks like this:
|
||||
|
||||
function __autoload($class) {
|
||||
require str_replace('_', '/', $class) . '.php';
|
||||
return true;
|
||||
}
|
||||
|
||||
A modified version with HTML Purifier would look like this:
|
||||
|
||||
function __autoload($class) {
|
||||
if (HTMLPurifier_Bootstrap::autoload($class)) return true;
|
||||
require str_replace('_', '/', $class) . '.php';
|
||||
return true;
|
||||
}
|
||||
|
||||
Note that there *is* some custom behavior in our autoloader; the
|
||||
original autoloader in our example would work for 99% of the time,
|
||||
but would fail when including language files.
|
||||
|
||||
AN __autoload FUNCTION IS DECLARED AFTER OUR AUTOLOADER IS REGISTERED
|
||||
spl_autoload_register() has the curious behavior of disabling
|
||||
the existing __autoload() handler. Users need to explicitly

Users should also be on guard if they use a version of PHP previous
|

to 5.1.2 without an autoloader--HTML Purifier will define __autoload()
|
||||
for you, which can collide with an autoloader that was added by *you*
|

later.

You can do these operations by yourself--in fact, you must modify your own

autoload handler if you are using a version of PHP earlier than PHP 5.1.2
