日本語
$ carsという名前のインデックス配列を作成し、3つの要素を割り当て、配列値を含むテキストを印刷します。
<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">配列</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">エコー</span><span class="token string double-quoted-string">「私は好き」</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">" そして "</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>
$ ageという名前の連想配列を作成します：
<span class="token php language-php"><span class="token delimiter important"><？php</span> <span class="token variable">$ age</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">"bill"</span> <span class="token operator">=></span> <span class="token string double-quoted-string">"60"</span> <span class="token punctuation">、</span> <span class="token string double-quoted-string">"Steve"</span> <span class="token operator">=></span> <span class="token string double-quoted-string">"56"</span> <span class="token punctuation">、</span> <span class="token string double-quoted-string">"mark"</span> <span class="token operator">=></span> <span class="token string double-quoted-string">"31"</span> <span class="token punctuation">）</span></mark><span class="token punctuation"></span> <span class="token punctuation">;</span> <span class="token keyword">エコー</span><span class="token string double-quoted-string">「法案は」</span> <span class="token operator">。</span> <span class="token variable">$ age</span> <span class="token punctuation">[</span> <span class="token string single-quoted-string">'bill'</span> <span class="token punctuation">]</span> <span class="token operator">。</span> <span class="token string double-quoted-string">「年齢。」</span> <span class="token punctuation">;</span> <span class="token delimiter important">？></span>
インデックスアレイの値を反復して印刷します。

繰り返して、連想配列のすべての値を印刷します。
