The closing marker for doc strings is no longer required to be followed by a
|
|
semicolon or newline. Additionally the closing marker may be indented, in
|
|
which case the indentation will be stripped from all lines in the doc string.

A new <classname>CompileError</classname> exception has been added, from

compilation errors will now throw a <classname>CompileError</classname>

<para>

Support for full case-mapping and case-folding has been added. Unlike simple
|
|
case-mapping, full case-mapping may change the length of the string. For
|
|
example:
|
|
<informalexample>

<programlisting role="php">

The <literal>mb_ereg_*</literal> functions now support named captures.

|
Matching functions like <function>mb_ereg</function> will now return named
|
|
captures both using their group number and their name, similar to PCRE:
|

<informalexample>

<programlisting role="php">

<![CDATA[

<?php
|
|
mb_ereg('(?<word>\w+)', '国', $matches);

// => [0 => "国", 1 => "国", "word" => "国"];
|
|
?>
|
|
]]>
|
|
</programlisting>
|
|
</informalexample>
|
|
Additionally, <function>mb_ereg_replace</function> now supports the
|
|
<code>\k<></code> and <code>\k''</code> notations to reference named
|
|
captures in the replacement string:
|
|
<informalexample>
|
|
<programlisting role="php">
|
|
<![CDATA[
|
|
<?php
|
|
mb_ereg_replace('\s*(?<word>\w+)\s*', "_\k<word>_\k'word'_", ' foo ');
|
|
// => "_foo_foo_"
|
|
?>
|
|
]]>
|
|
</programlisting>
|
|
</informalexample>
|
|
<code>\k<></code> and <code>\k''</code> can also be used for numbered
|
|
references, which also works with group numbers greater than 9.
