Of course, you can browse it in PHPMYADMIN. But there must be some omissions after all. So I wrote a script (PHP) to compare database differences to facilitate myself. Of course the code is very simple, so I won’t explain it. Paste the code:

Copy the code The code is as follows:

mysql_connect('localhost','root','root');
mysql_select_db('tablea'); //Standard database
$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');//Database that needs to be compared
$q2 = mysql_query("show tables");
while($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][] = $v1;
}
}
}
}
}
echo "
"; 
print_r($e);//The table is missing
print_r($f);//The fields of the table are missing
?>
