PHP之namespace renault espace espace auto espace.net patents

namespace(命名空间)相当于函数、类，划分了一个区域，这样子就使得在同个页面中可以require相同的类，使用相同名字的函数
： 在项目中比较少用

<code><span>//name.php</span><span><?php </span><span>//命名要使用复合名称</span><span>namespace</span><span>me</span>\<span>mine</span>;
<span><span>class</span><span>me</span>{</span><span>public</span><span><span>function</span><span>__construct</span><span>()</span>{</span><span>echo</span><span>'name'</span>.<span>'<br>'</span>;
    }
    <span>public</span><span><span>function</span><span>name</span><span>()</span>{</span><span>echo</span><span>'i use space'</span>.<span>'<br>'</span>;
    }
}
<span>//$me = new me();</span><span><span>function</span><span>me</span><span>()</span>{</span><span>echo</span><span>'is me'</span>.<span>'<br>'</span>;
}</span></code>

<code><span>//common.php</span><span><?php </span><span><span>class</span><span>me</span>{</span><span>public</span><span><span>function</span><span>__construct</span><span>()</span>{</span><span>echo</span><span>'no namespace'</span>.<span>'<br>'</span>;
    }
}</span></code>

<code><span><span><?php </span><span>//建议使用别名</span><span>use</span><span>me</span>\<span>mine</span><span>as</span><span>i</span>;
<span>require</span><span>'./name.php'</span>;
<span>require</span><span>'./common.php'</span>;

<span>$me</span> = <span>new</span> i\me();
<span>$me</span>->name();
i\me();

<span>$com</span> = <span>new</span> me();</span></span></code>

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

以上就介绍了PHP之namespace，包括了espace方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
