基于php，点亮代码生成技能树

<?php
$table = ($_GET['action']);
/*生成后端*/
$fileName="core/Motherboard.php";
$handle=fopen($fileName,"r");//使用打开模式为r
$contents=fread($handle,filesize($fileName));//读为二进制
$contents = preg_replace('/\{table\}/', $table, $contents);//替换后台表名
//查询表里的列
$sql = "select COLUMN_NAME from information_schema.COLUMNS where table_name = :table_name and table_schema = '".$config['dbname']."' ";
$data = array(
        ':table_name'=>$table
        );
$data = $db->queryAll($sql,$data);
foreach ($data as $key=>$value){
    $arrays[] = "
    $".$value['COLUMN_NAME']." = \$_REQUEST['".$value['COLUMN_NAME']."'];
    ";
}
$field=implode("",$arrays);
$contents = preg_replace('/\{field\}/', $field, $contents);//替换后台列表
 
foreach ($data as $key=>$value){
    $arr[] = "
    '".$value['COLUMN_NAME']."' => $".$value['COLUMN_NAME'].",
    ";
}
$data=implode("",$arr);
$contents = preg_replace('/\{data\}/', $data, $contents);//替换后台列表
/*生成后端*/
$ctxtsubmit=$contents;
$f=fopen("action/".$_GET['action'].".php", "wb");
//$text=utf8_encode($ctxtsubmit);
//先用函数utf8_encode将所需写入的数据变成UTF编码格式。
$text="\xEF\xBB\xBF".$ctxtsubmit;
//"\xEF\xBB\xBF",这串字符不可缺少，生成的文件将成为UTF-8格式，否则依然是ANSI格式。
fputs($f, $text);
//写入。
fclose($f);
