HTMLタグを含む文字列変数（$ str）の値を出力します。
<span class="token php language-php"><span class="token delimiter important"><？php</span> <span class="token variable">$ str</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"私は上海が大好き！"</span> <span class="token punctuation">;</span> <span class="token keyword">印刷</span><span class="token variable">$ str</span> <span class="token punctuation">;</span> <span class="token keyword">「</span> <span class="token string double-quoted-string"><br>なんていい日だ！」</span> <span class="token punctuation">;</span> <span class="token delimiter important">？></span></span>
2つの文字列変数を連結します。
<span class="token php language-php"><span class="token delimiter important"><？php</span> <span class="token variable">$ str1</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"私は上海が大好き！"</span> <span class="token punctuation">;</span> <span class="token variable">$ str2</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"なんていい日！"</span> <span class="token punctuation">;</span> <span class="token variable">$ str1</span><span class="token keyword">を印刷します</span><span class="token operator">。</span> <span class="token string double-quoted-string">""</span> <span class="token operator">。</span> <span class="token variable">$ str2</span> <span class="token punctuation">;</span> <span class="token delimiter important">？></span></span>
出力配列値：
<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">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 punctuation">;</span> <span class="token string double-quoted-string">「ビルゲイツIS」</span><span class="token keyword">を印刷します</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></span>
出力テキスト：
<span class="token php language-php"><span class="token delimiter important"><？php</span> <span class="token string double-quoted-string">「このテキスト」</span><span class="token keyword">を印刷します</span><span class="token string double-quoted-string"> 複数の範囲 行。 "</span> <span class="token punctuation">;</span> <span class="token delimiter important">？></span></span>
単一の引用と二重引用符の違い。単一の引用符は、値ではなく変数名が出力されます。
<span class="token php language-php"><span class="token delimiter important"><？php</span> <span class="token variable">$ color</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"red"</span> <span class="token punctuation">;</span> <span class="token keyword">印刷</span><span class="token string double-quoted-string">「バラは<span class="token interpolation"><span class="token variable">$ color</span></span> 」</span> <span class="token punctuation">;</span> <span class="token keyword">印刷</span><span class="token string double-quoted-string">「<br>」</span> <span class="token punctuation">;</span> <span class="token keyword">印刷</span><span class="token string single-quoted-string">「バラは$ color」</span> <span class="token punctuation">;</span> <span class="token delimiter important">？></span></span>
