In your question, you asked about a function called htmlspecialentity(), I think the functions you mean are htmlspecialchars() and htmlentities().

Here's the documentation for both functions:

htmlentities()

This function is identical to htmlspecialchars() in all ways, except with htmlentities(), all characters which have HTML character entity equivalents are translated into these entities.

htmlspecialchars()

Certain characters have special significance in HTML, and should be represented by HTML entities if they are to preserve their meanings. This function returns a string with these conversions made. If you require all input substrings that have associated named entities to be translated, use htmlentities() instead.

As you can see, they're pretty similar. The only difference is that htmlentities() converts every HTML character from it's ASCII value into it's HTML entity and htmlspecialchars() only converts a subset of characters into their HTML entity.

Most of the time htmlspecialchars is sufficient.
