<code><span><?php</span><span>$arr</span> = <span>array</span>(<span>'aa'</span>,<span>'bb'</span>,<span>'cc'</span>,<span>'dd'</span>); <span>unset</span>(<span>$arr</span>[<span>2</span>]); print_r(<span>$arr</span>); <span>?></span><span>Array</span> ( [<span>0</span>] => aa[<span>1</span>] => bb [<span>3</span>] => dd)</code>
unset最大缺点是没有重建数组索引 后来发现有array_splice函数
<code><span><?php</span><span><span>function</span><span>array_remove</span><span>(&<span>$arr</span>, <span>$offset</span>)</span> {</span> array_splice(<span>$arr</span>, <span>$offset</span>, <span>1</span>);
}
<span>$arr</span> = <span>array</span>(<span>'aa'</span>,<span>'bb'</span>,<span>'cc'</span>,<span>'dd'</span>);
array_remove(<span>$arr</span>, <span>2</span>);
print_r(<span>$arr</span>);
<span>?></span><span>Array</span> ( [<span>0</span>] => aa [<span>1</span>] => bb [<span>2</span>] => dd) </code>以上就介绍了php 去除数组中的某个元素，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
