Erstellen Sie ein Indexarray mit dem Namen $ Cars, weisen Sie ihm drei Elemente zu und drucken Sie den Text mit dem Array -Wert aus:
<span class="token php language-php"><span class="token delimiter important"><? Php</span> <span class="token variable">$ cars</span> <span class="token operator">=</span><span class="token keyword"></span></span><mark> <span class="token keyword">Array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"Volvo"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"BMW"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"Toyota"</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">;</span> <span class="token keyword">Echo</span> <span class="token string double-quoted-string">"ich mag"</span> <span class="token operator">.</span> <span class="token variable">$ Cars</span> <span class="token punctuation">[</span> <span class="token number">0</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">","</span> <span class="token operator">.</span> <span class="token variable">$ Cars</span> <span class="token punctuation">[</span> <span class="token number">1</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">" Und "</span> <span class="token operator">.</span> <span class="token variable">$ Cars</span> <span class="token punctuation">[</span> <span class="token number">2</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">"."</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span>
Erstellen Sie ein assoziatives Array mit dem Namen $ Age:

Den Wert des Indexarrays iterieren und ausdrucken:

Alle Werte des assoziativen Arrays iterieren und ausdrucken:
