                <h2>Description</h2>
                <p>The <code>array()</code> function creates an array.</p>
                <p>It is a language construct used to represent literal arrays, it is not a regular function.</p>
				<p>The following table summarizes the technical details of this function.</p>
				<div class="shadow">
					<table class="data description">
                        <tr>
                            <th style="width: 120px;">Return&nbsp;Value:</th>
                            <td>Returns an array of the parameters.</td>
                        </tr>
                        <tr>
                            <th>Version:</th>
                            <td>PHP 4+</td>
                        </tr>
					</table>
				</div>

				<h2>Syntax</h2>
				<p>The basic syntax of the <code>array()</code> function is given with:</p>
				<div class="shadow">
					<div class="syntax"><span class="keyword">array</span>(<em>index=>value</em>, <em>index=>value</em>, ...);</div>
				</div>
                <p>The <em>index</em> may be of type string or integer. When indices are integers array is called <strong><em>indexed array</em></strong>, and when indices are strings array is typically called <strong><em>associative array</em></strong>.</p>
                <p>When index is omitted or not specified, an integer index is automatically generated, starting from 0. If index is an integer, next generated index will be the bigger integer (previous index + 1). Also, if two identical index are defined, the last one overwrites the previous one.</p>
				<p>The following example shows the <code>array()</code> function in action.</p>
