<span class="token delimiter important">?></span></span>

직접 시도하십시오

예 2

이 예에서는 " %u "형식이 있거나없는 crc32() 의 결과를 출력합니다 (결과는 동일합니다).

 <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 function">crc32</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"Hello World!"</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>
<span class="token keyword">echo</span> <span class="token string single-quoted-string">&#39; %u :&#39;가없는 echo</span> <span class="token operator">.</span> <span class="token variable">$ str</span> <span class="token operator">.</span> <span class="token string double-quoted-string">"<br>"</span> <span class="token punctuation">;</span>

<span class="token delimiter important">?></span></span>

위 코드의 출력 :

 %u : 461707669없이
%u : 461707669

예 3

이 예에서는 " %u "형식이 있거나없는 crc32() 의 결과를 출력합니다 (결과는 다릅니다).
