我希望最后一个数据有margin-bottom: 0px;
函数.php
$SQL_7 = mysqli_query($Connection, "SELECT * FROM users");
$row_number = mysqli_num_rows($SQL_7);
$i = 1;
while ($Fetch_7 = mysqli_fetch_array($SQL_7)) {
// If last row remove margin bottom
if ($i < $row_number) {
$get_margin = "style='margin-bottom: 0px;'";
}
}
索引.php
<div class='margin_bottom_10' <?php echo $get_margin; ?> >
Test
</div>
例
<div id='data1' class='margin_bottom_10'>Test</div>
<div id='data2' class='margin_bottom_10'>Test</div>
<div id='data3' class='margin_bottom_10' style='margin-bottom: 0px;'>Test</div>
您应该在
while 循环中递增$i。 $i++
向变量添加一个。您希望此值与您的行计数匹配,因为这将是最后一条记录。如果您有 10 个用户,经过 10 次循环后$i将等于 10,然后您的子句将添加样式标记。
<?php
$SQL_7 = mysqli_query($Connection, "SELECT * FROM users");
$row_number = mysqli_num_rows($SQL_7);
$i = 0;
while ($Fetch_7 = mysqli_fetch_array($SQL_7)) {
// increment i
$i++;
// If last row remove margin bottom
if ($i == $row_number) {
$get_margin = "style='margin-bottom: 0px;'"; // Do show
} else {
$get_margin = ""; // Dont show
}
}
编辑:最好从零开始!
increment
$i
每个步骤的时间以及何时$i= num_of_row
断言$get_margin
需要margin
`$SQL_7 = mysqli_query($Connection, "SELECT * FROM users");
$row_number = mysqli_num_rows($SQL_7);
$i = 1;
while ($Fetch_7 = mysqli_fetch_array($SQL_7)) {
// If last row remove margin bottom
if ($i == $row_number)
$get_margin = "style='margin-bottom: 0px;'";
$i++;
}
?>
<div id='data1' class='margin_bottom_10'>Test</div>
<div id='data2' class='margin_bottom_10'>Test</div>
<div id='data3' class='margin_bottom_10' <?php echo $get_margin; ?>>Test</div>`
