Sham@双目瞿最近打包v1.5的时候，因为把自己的数据库信息、appid等信息删除了，导致后端如果再次使用或者他人使用时，需要手动查找多个文件进行替换，于是想起来是否能像wordpress初次使用时进行安装生成，于是查询网上资料，有了初步想法和代码，如下：
目前使用layui的话，只能用2个文件来实现，暂时还未找到并到1个文件的方法：
index.php页（设置页）
<!DOCTYPE html>
<html lang="en">

<meta charset="utf-8">

.layui-input{

</script>
</body>
</html>然后是安装生成页，install.php
<?php
error_reporting(0);
if(isset($_POST['dbaddress']) && isset($_POST['dbuser'])){
$servername = $_POST['dbaddress'];
$username = $_POST['dbuser'];
$password = $_POST['dbpsw'];
$mysqlname = $_POST['dbname'];
$con = mysqli_connect($servername, $username, $password, $mysqlname) or exit("{".'"code": 1,'. '"msg": "数据库连接失败，请检查数据库信息是否准确"'."}");
mysqli_query($con,"set names utf8");
if(!file_exists('public')){
mkdir('public',0777);
}
touch('public/dbcon.php');
$read = fopen('public/dbcon.php','w');
$content = '<?php
$servername = "'.$servername.'";
$username = "'.$username.'";
$password = "'.$password.'";
$mysqlname = "'.$username.'";
$con = mysqli_connect($servername, $username, $password, $mysqlname);
mysqli_query($con,"set names utf8");
$url="'.$_POST['wxurl'].'";
$imgurl="'.$_POST['photourl'].'";
$appid="'.$_POST['appid'].'";
$appsecret="'.$_POST['appsecret'].'";
?>';
fwrite($read,$content);
$sql = file_get_contents('db.sql');
$sqls = explode(';',$sql);
$sqlnum = count($sqls);
for($i=0;$i<$sqlnum;$i++){
$res = $con->query($sqls[$i]);
if($res){
$done++;
}
}
if($i==$sqlnum){
echo "{".'"code": 0,'. '"msg": "初始化成功，可直接访问后台"'."}";
}else{
echo "{".'"code": 1,'. '"msg": "失败，请重试"'."}";
}
}
?>这里的db.sql是已经上传至同一目录里，后面会考虑变成在index.php里上传。
初次使用时，打开index.php，然后会有个表单，提交后，会在数据库内将db.sql导入到数据库，然后再在public目录下生成dbcon.php，里面有数据库信息，网址以及appid等信息，这样就不需要一个个设置了，需要的时候调用就行了。
待优化后放入v2版后端中，先记录备忘
