use Illuminate\Support\Facades\Schema; use DB; public function getDatabaseColumns() { $tables = DB::select('show tables'); $tables = array_column($tables, 'Tables_in_new_bcc_web'); $columns = ['email', 'user_name', 'nick_name', 'first_name', 'last_name']; // dd(Schema::getConnection()); foreach ($tables as $key => $value) { foreach ($columns as $k => $v) { if (Schema::hasColumn($value, $v)) { $table[] = $value; }; } // $columns[] = Schema::getColumnListing('users'); } $table = array_unique($table); dd($table); }
use Illuminate\Support\Facades\Schema; Schema::getColumnListing('user'); Schema::hasColumn($table, $column_name)
public function getDatabaseColumns() { $tables = array_map('reset', \DB::select('SHOW TABLES')); $columns = ['email', 'user_name', 'nick_name', 'first_name', 'last_name']; foreach ($tables as $key => $value) { foreach ($columns as $k => $v) { if (Schema::hasColumn($value, $v)) { $table[] = $value; }; } } $table = array_unique($table); dd($table); }

//获取表 Schema::connection('mysql') Illuminate\Database\Schema\MySqlBuilder Schema::connection('mysql')->getAllTables(); Schema::connection('mysql')->getColumnListing() //获取表的字段 getColumnListing() //获取表的字段 hasTable() //是否包含表 dropAllTables //删除所有的表 慎用 getAllViews //获取所有的视图 dropIfExists() 如果表存在就删除 $tables = Schema::getColumnListing($tableName); //返回表字段信息
