mysql数据库差异比较的PHP代码
当然可以去PHPMYADMIN里浏览一下。但是终究有遗漏吧。所以自己写了个,比较数据库差异的脚本(PHP的),方便一下自己。当然代码很简单,就不讲解了,贴代码:
复制代码 代码如下:
mysql_connect('localhost','root','root');
mysql_select_db('tablea'); //标准的数据库
$q = mysql_query("show tables");
while($s = mysql_fetch_array($q)){
$name = $s[0];
$q1 = mysql_query("desc $name");
while ($s1 = mysql_fetch_array($q1)) {
$a[$name][] =$s1[0];
}
}
mysql_close();
mysql_connect('localhost','root','root');
mysql_select_db('tableb');//需要比较的数据库
$q2 = mysql_query("show tables");
while($s2 = mysql_fetch_array($q2)){
$name2= $s2[0];
$q3 = mysql_query("desc $name2");
while ($s3 = mysql_fetch_array($q3)) {
$aa[$name2][] =$s3[0];
}
}
mysql_close();
$f = $e = array();
$str = $fuhao ='';
foreach($a as $k=>$v){
if(!is_array($aa[$k])){
$e[] = $k;
}
else{
if(count($aa[$k]) count($v)){
foreach($v as $k1=>$v1){
if(!in_array($v1,$aa[$k])){
$f[$k][] = $v1;
}
}
}
}
}
echo "
"; <br>print_r($e);//缺少表 <br>print_r($f);//缺少表的字段 <br>?> <br>

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
