위에있는 code처럼 저는 if문을 이런식으로쓰는데 잘못된방법인가요??

 

 

 

<?php

if ($sir) {

 

} else {

 

}

?>

이렇게 쓰는게 맞는건가요???

확인해보세요 가독성 때문에 괄호를 넣어주는게 좋습니다.

아무래도.. 코드를 사용하실때

 

 

1<?php if($sir):?>
2$a = 1;
3<?else:?>
4$b = 1;
5<?endif;?>
 

 

문법의 차이보다는

 

PHP 기호에서 사용오류를 발생시키는거 같은데요

 

요즘 PHP를 사용할때

예전에 

</p><p><? </p><p>$PHP = "codes";</p><p>?></p><p>

하고 사용하던것이

항상

</p><p><?php </p><p>$PHP = "codes";</p><p>?></p><p><span style="font-size: 14.6667px;">
 

로 사용해야 하더라구요

 

위의 문장도

중간 else와 endif 앞에 php가 빠져서 그런거 같습니다.

위 방식도 가능하지만

 

<?php  $a=($sir)?"1":"2"; ?>

​

이런식으로도 가능합니다.​

아래 말씀하신거 처럼 하거나

 

<?php

if ($sir) :

 

else :

 

endif;

?>

하시면 됩니다.
