조건조립이 이루어지는 Yii2 쿼리에 대한 자세한 설명-PHP 튜토리얼-php.cn

<p>Yii2의 쿼리 조건을 숙지한 후 Active를 사용하세요. 레코드는 데이터 쿼리에 매우 편리합니다. 아래에서는 where() 메서드의 조건 조합 방법을 소개합니다. </p> <h2 style="font-family:'Microsoft YaHei UI Light', SimHei, SimSun, sans-serif;line-height:1.1;color:rgb(66,139,209);">1 구문</h2> <p style="white-space:pre-wrap;">Yii2는 <code class="hljs bash" style="font-family:Consolas, 'Liberation Mono', Menlo, Courier, monospace;font-size:12px;padding:.3em;color:rgb를 사용합니다.
