Executes the regular expression
match with multibyte support, and returns <em>1</em> if matches are found.
If the optional <em><code class="parameter">regs</code></em> parameter was specified, the function
returns the byte length of matched part, and the <span class="type"><a href="language.types.array.html" class="type array">array</a></span>
<em><code class="parameter">regs</code></em> will contain the substring of matched
string. The function returns <em>1</em> if it matches with the empty
string. If no matches are found or an error happens, <strong><code>FALSE</code></strong> will be
returned.
