我的应用程序中有一个 foreach
语句,用于回显我的数据库结果列表:
';回声 $fp['project_name'];回声'</div>';}?>我想:
每隔三个结果,给 div 一个不同的类.我怎样才能做到这一点?
解决方案 您可以使用计数器和 模数/模数运算符如下:
I have a foreach
statement in my app that echos a list of my database results:
<?php
foreach($featured_projects as $fp) {
echo '<div class="result">';
echo $fp['project_name'];
echo '</div>';
}
?>
I would like to:
On every third result, give the div a different class. How can I achieve this?
解决方案 You can use a counter and the modulo/modulus operator as per below:
<?php
// control variable
$counter = 0;
foreach($featured_projects as $fp) {
// reset the variable
$class = '';
// on every third result, set the variable value
if(++$counter % 3 === 0) {
$class = ' third';
}
// your code with the variable that holds the desirable CSS class name
echo '<div class="result' . $class . '">';
echo $fp['project_name'];
echo '</div>';
}
?>
