문자열 변수 ($ str)의 값을 출력에 기록하십시오.
<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">"안녕하세요 세계!"</span> <span class="token punctuation">;</span> <span class="token keyword">echo</span> <span class="token variable">$ str</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span></span>
HTML 태그를 포함하여 문자열 변수 ($ str)의 값을 출력에 기록하십시오.
<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">"안녕하세요 세계!"</span> <span class="token punctuation">;</span> <span class="token keyword">echo</span> <span class="token variable">$ str</span> <span class="token punctuation">;</span> <span class="token keyword">에코</span> <span class="token string double-quoted-string">"<br> 정말 좋은 날!"</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span></span>
두 문자열 변수를 연결하십시오.
<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">"Hello World!"</span> <span class="token punctuation">;</span> <span class="token variable">$ str2</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"정말 좋은 날!"</span> <span class="token punctuation">;</span> <span class="token keyword">echo</span> <span class="token variable">$ str1</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>
출력에 배열 값을 쓰십시오.
<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">"Peter"</span> <span class="token operator">=></span> <span class="token string double-quoted-string">"35"</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span> <span class="token keyword">에코</span> <span class="token string double-quoted-string">"피터는"</span> <span class="token operator">.</span> <span class="token variable">$ Age</span> <span class="token punctuation">[</span> <span class="token string single-quoted-string">'Peter'</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">"나이."</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span></span>
출력에 텍스트를 작성하십시오.
<span class="token php language-php"><span class="token delimiter important"><? php</span> <span class="token keyword">에코</span> <span class="token string double-quoted-string">"이 텍스트 다중에 걸쳐 있습니다 라인.

여러 매개 변수 사용 방법 :
<span class="token php language-php"><span class="token delimiter important"><? php</span> <span class="token keyword">echo</span> <span class="token string single-quoted-string">'this'</span> <span class="token punctuation">,</span> <span class="token string single-quoted-string">'string'</span> <span class="token punctuation">,</span> <span class="token string single-quoted-string">'was'</span> <span class="token punctuation">,</span> <span class="token string single-quoted-string">'made'</span> <span class="token punctuation">,</span> <span class="token string single-quoted-string">'여러 매개 변수가 있습니다.'</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span></span>
단일 따옴표와 이중 인용문의 차이. 단일 따옴표는 값이 아닌 변수 이름을 출력합니다.
<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">"빨간색"</span> <span class="token punctuation">;</span> <span class="token keyword">에코</span> <span class="token string double-quoted-string">"장미는 <span class="token interpolation"><span class="token variable">$ color</span></span> "</span> <span class="token punctuation">;</span> <span class="token keyword">에코</span> <span class="token string double-quoted-string">"<br>"</span> <span class="token punctuation">;</span> <span class="token keyword">Echo</span> <span class="token string single-quoted-string">'장미는 $ color'입니다</span> <span class="token punctuation">.</span> <span class="token delimiter important">?></span></span>
단순화 된 구문 (short_open_tag 구성 설정에만 적용 가능) :
<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">"빨간색"</span> <span class="token punctuation">;</span> <span class="token delimiter important">?></span></span> <span class="token tag"><span class="token tag"><span class="token punctuation"><p></span></span> <span class="token punctuation">장미</span></span> 는 <span class="token php language-php"><span class="token delimiter important"><? =</span> <span class="token variable">$ color</span> 입니까 <span class="token delimiter important">?></span></span> <span class="token tag"><span class="token tag"><span class="token punctuation"></</span> p</span> <span class="token punctuation">></span></span>
