我有一个带有键的2D电影数组,这些键是通过MySQL Db通过phpMyAdmin生成的。
(从复制粘贴中删除的情节)
$films = array(
array('title' => 'Batman Begins','yr' => '2005','genre' => 'Action, Adventure','plot' => 'After training with his mentor, Batman begins his w...')
array('title' => 'Ted 2','yr' => '2015','genre' => 'Comedy','plot' => 'Newlywed couple Ted and Tami-Lynn want to have a baby, but in order to...')
array('title' => 'Ted','yr' => '2012','genre' => 'Comedy, Fantasy','plot' => 'As the result of a childhood wish, John Bennett\'s teddy bear, ...')
array('title' => 'Interstellar','yr' => '2014','genre' => 'Adventure, Sci-Fi','plot' => 'A team of explorers travel through a wormhole in spa...')
);
我还有一个foreach循环,循环遍历2D数组并将结果作为表格返回:
$out = "";
$out .= "<table>";
foreach($films as $key => $element){
$out .= "<tr>";
foreach($element as $subk => $subel){
$out .= "<td>$subel</td>";
}
$out .= "</tr>";
}
$out .="<table>";
echo $out;
根据我在网页上看到的结果,显示如下:
蝙蝠侠2005年开始行动,冒险训练后......
我如何能够将密钥显示为列标题?我已尝试在主要循环中创建另一个foreach循环,但返回标题如下:titleyrgenreplottitleyrgenreplot
等。
我如何才能在表格中正确格式化,以便出现标题?
这也只是一个小而快速的问题:我不是将数据库从phpMyAdmin导出为PHP数组,而是在MySQL数据库表中进行更改后如何更新PHP /网页?

以下是获取标题的方法:
$headers="<thead><tr>";
foreach($films as $key => $element){
$headers.= "<th>$key</th>";
}
$headers.= "</tr></thead>";
所以你的代码现在应该是这样的:
$out = "";
$out .= "<tbody>";
$headers="<table><thead><tr>";
foreach($films as $key => $element){
$headers.= "<th>$key</th>";
$out .= "<tr>";
foreach($element as $subk => $subel){
$out .= "<td>$subel</td>";
}
$out .= "</tr>";
}
$out .="</tbody><table>";
$headers.= "</tr></thead>";
echo $headers;
echo $out;

为了将字段显示为标题,我们只需循环遍历第一个子数组的键,然后在循环遍历整个结果之前添加另一行(<tr>
)和表头(<th>
)。通常我们只显示一次标题。
$out = "";
$out .= "<table>";
$out .= "<tr>";
foreach($films[0] as $key => $value)
{
$out .= "<th>".$key."</th>";
}
$out .= "</tr>";
foreach($films as $key => $element){
$out .= "<tr>";
foreach($element as $subk => $subel){
$out .= "<td>$subel</td>";
}
$out .= "</tr>";
}
$out .="<table>";
echo $out;
