Ausgehend vom dritten Element des Arrays und geben Sie die verbleibenden Elemente im Array zurück:
<span class="token php language-php"><span class="token delimiter important"><? Php</span> <span class="token variable">$ a</span> <span class="token operator">=</span> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"rot"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"grün"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"blau"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"gelb"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"braun"</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span> <span class="token function">print_r</span> <span class="token punctuation">(</span><span class="token function"></span></span><mark> <span class="token function">Array_Slice</span> <span class="token punctuation">(</span> <span class="token variable">$ A</span> <span class="token punctuation">,</span> <span class="token number">2</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">)</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span>
Nehmen Sie es aus dem zweiten Element des Arrays und geben Sie nur zwei Elemente zurück:
<span class="token php language-php"><span class="token delimiter important"><? Php</span> <span class="token variable">$ a</span> <span class="token operator">=</span> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"rot"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"grün"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"blau"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"gelb"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"braun"</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span> <span class="token function">print_r</span> <span class="token punctuation">(</span><span class="token function"></span></span><mark> <span class="token function">Array_Slice</span> <span class="token punctuation">(</span> <span class="token variable">$ A</span> <span class="token punctuation">,</span> <span class="token number">1</span> <span class="token punctuation">,</span> <span class="token number">2</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">)</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span>
Verwenden Sie negative Startparameter :
<span class="token php language-php"><span class="token delimiter important"><? Php</span> <span class="token variable">$ a</span> <span class="token operator">=</span> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"rot"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"grün"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"blau"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"gelb"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"braun"</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span> <span class="token function">print_r</span> <span class="token punctuation">(</span><span class="token function"></span></span><mark> <span class="token function">Array_Slice</span> <span class="token punctuation">(</span> <span class="token variable">$ a</span> <span class="token punctuation">,</span> <span class="token operator">-</span> <span class="token number">2</span> <span class="token punctuation">,</span> <span class="token number">1</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">)</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span>
Setzen Sie den Parameter für die Erhaltung auf True:
<span class="token php language-php"><span class="token delimiter important"><? Php</span> <span class="token variable">$ a</span> <span class="token operator">=</span> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"rot"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"grün"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"blau"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"gelb"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"braun"</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span> <span class="token function">print_r</span> <span class="token punctuation">(</span><span class="token function"></span></span><mark> <span class="token function">Array_Slice</span> <span class="token punctuation">(</span> <span class="token variable">$ a</span> <span class="token punctuation">,</span> <span class="token number">1</span> <span class="token punctuation">,</span> <span class="token number">2</span> <span class="token punctuation">,</span> <span class="token constant boolean">true</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">)</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span>
Verarbeiten Sie Stringschlüsselnamen und Ganzzahlschlüsselnamen:
