The distinct iterator object used internally by the <a href="control-structures.foreach.html" class="link"><em>foreach</em> construct</a> can only be obtained (in the relevant part here) from objects, so objects of this class serve the purpose of providing the hook through which this internal object can be obtained. As a convenience, this class also implements the <a href="class.iterator.html" class="classname">Iterator</a> interface, allowing the collection of values to be navigated using the methods defined in that interface. Both these methods and the internal iterator objects provided to <em>foreach</em> are backed by the same state (e.g. the position of the iterator and its current value). </p> <p class="para"> Subclasses may provide richer functionality. </p> </div> <div class="section" id="intliterator.synopsis"> <h2 class="title">Class synopsis</h2> <div class="classsynopsis"> <div class="ooclass"></div> <div class="classsynopsisinfo"> <span class="ooclass"> <strong class="classname">IntlIterator</strong> </span> <span class="oointerface">implements <span class="interfacename"><a href="class.iterator.html" class="interfacename">Iterator</a></span> </span> {</div> <div class="classsynopsisinfo classsynopsisinfo_comment">/* Methods */</div> <div class="methodsynopsis dc-description"> <span class="modifier">public</span> <span class="type">ReturnType</span> <span class="methodname"><a href="intliterator.current.html" class="methodname">current</a></span> ( <span class="methodparam">void</span> )</div> <div class="methodsynopsis dc-description"> <span class="modifier">public</span> <span class="type">ReturnType</span> <span class="methodname"><a href="intliterator.key.html" class="methodname">key</a></span> ( <span class="methodparam">void</span> )</div> <div class="methodsynopsis dc-description"> <span class="modifier">public</span> <span class="type">ReturnType</span> <span class="methodname"><a href="intliterator.next.html" class="methodname">next</a></span> ( <span class="methodparam">void</span> )</div> <div class="methodsynopsis dc-description"> <span class="modifier">public</span> <span class="type">ReturnType</span> <span class="methodname"><a href="intliterator.rewind.html" class="methodname">rewind</a></span> ( <span class="methodparam">void</span> )</div> <div class="methodsynopsis dc-description"> <span class="modifier">public</span> <span class="type">ReturnType</span> <span class="methodname"><a href="intliterator.valid.html" class="methodname">valid</a></span> ( <span class="methodparam">void</span> )</div> }</div> </div> </div> <h2>Table of Contents</h2><ul class="chunklist chunklist_reference"><li><a href="intliterator.current.html">IntlIterator::current</a> — Get the current element</li><li><a href="intliterator.key.html">IntlIterator::key</a> — Get the current key</li><li><a href="intliterator.next.html">IntlIterator::next</a> — Move forward to the next element</li><li><a href="intliterator.rewind.html">IntlIterator::rewind</a> — Rewind the iterator to the first element</li><li><a href="intliterator.valid.html">IntlIterator::valid</a> — Check if curent position is valid</li></ul> </div> <hr /><div class="manualnavbar" style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="class.intlexception.html">IntlException</a></div> <div class="next" style="text-align: right; float: right;"><a href="intliterator.current.html">IntlIterator::current</a></div> <div class="up"><a href="book.intl.html">intl</a></div> <div class="home"><a href="index.html">PHP Manual</a></div> </div></body></html>
