natcasesort

名稱:natcasesort

分類:數組

所屬語言:php

一句話介紹:用“自然排序”算法對數組進行不區分大小寫字母的排序。

實例

<span class="token php language-php"><span class="token delimiter important"><?php</span>
<span class="token variable">$temp_files</span> <span class="token operator">=</span> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"temp15.txt"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"Temp10.txt"</span> <span class="token punctuation">,</span>
<span class="token string double-quoted-string">"temp1.txt"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"Temp22.txt"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"temp2.txt"</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>

<span class="token function"></span></span><mark><span class="token function">natsort</span> <span class="token punctuation">(</span> <span class="token variable">$temp_files</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span></mark><span class="token punctuation"></span>
<span class="token keyword">echo</span> <span class="token string double-quoted-string">"自然排序："</span> <span class="token punctuation">;</span>
<span class="token function">print_r</span> <span class="token punctuation">(</span> <span class="token variable">$temp_files</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>
<span class="token keyword">echo</span> <span class="token string double-quoted-string">"<br />"</span> <span class="token punctuation">;</span>

<span class="token function"></span><mark><span class="token function">natcasesort</span> <span class="token punctuation">(</span> <span class="token variable">$temp_files</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span></mark><span class="token punctuation"></span>
<span class="token keyword">echo</span> <span class="token string double-quoted-string">"不區分大小寫的自然排序："</span> <span class="token punctuation">;</span>
<span class="token function">print_r</span> <span class="token punctuation">(</span> <span class="token variable">$temp_files</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>
<span class="token delimiter important">?></span>

以上代碼的輸出：

自然排序：

Array
(
[0] => Temp10.txt
[1] => Temp22.txt
[2] => temp1.txt
[4] => temp2.txt
[3] => temp15.txt
)

不區分大小寫的自然順序：

Array
(
[2] => temp1.txt
[4] => temp2.txt
[0] => Temp10.txt
[3] => temp15.txt
[1] => Temp22.txt
)
