90 php 命名空间

1.如果不加命名空间
test1.php

<code><span><span>function</span><span>test</span><span>()</span>
{</span><span>echo</span><span>'test1'</span>;
}</code>

test2.php

<code><span><span>function</span><span>test</span><span>()</span>
{</span><span>echo</span><span>'test2'</span>;
}</code>

test.php

<code><span>require</span><span>'test1.php'</span>;
<span>require</span><span>'test2.php'</span>;</code>

报错：

2.加了命名空间

test1.php

<code><span>namespace</span><span>Test1</span>;

<span><span>function</span><span>test</span><span>()</span>
{</span><span>echo</span><span>'test1'</span>;
}</code>

test2.php

<code><span>namespace</span><span>Test2</span>;

<span><span>function</span><span>test</span><span>()</span>
{</span><span>echo</span><span>'test2'</span>;
}</code>

test.php

<code><span>require</span><span>'test1.php'</span>;
<span>require</span><span>'test2.php'</span>;

Test1\test();
<span>echo</span><span>'<br>*************<br>'</span>;
Test2\test();</code>

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