注意：在MySql数据库中，“dob”是varchar，格式为：mm / dd / yyyy
出生日期，Cvrg生效日期，＆amp;当Cvrg到期日期到达Excel时，需要从mm / dd / yyyy更改为yyyymmdd。请参阅以下代码：

答案 0 :(得分：7)
根据特定格式的日期，您通常可以使用date和strtotime进行快速转换，如下所示：
// convert old date string to YYYYmmdd format
$date = date('Ymd', strtotime($old_date_string));
答案 1 :(得分：1)
你可以使用像
这样的mysql date_format functionDATE_FORMAT(dob,'%Y%m%d') AS 'Date of Birth',
今天给予20100118
编辑：因为dob是varchar你应该在foreach中检查它，只是使用字符串函数或cballou的答案将适合你
foreach ( $row as $key => $value )
{
if ( ( !isset($value) ) OR ( $value == "" ) )
{
$value = "\t";
}
else
{
if($key == 'Date of Birth') {
$exploded_value = explode("/",$value);
$value = $value[2].$value[0].$value[1];
// or according to cballou's answer
//$value = date('Ymd',strtotime($value));
}
$value = str_replace('"', '""', $value);
$value = '="' . $value . '"' . "\t";
// ^
// Added an equal sign
}
$line .= $value;
}
