php字符串包含某字符串，使用strpos

				$salary_levels = Db::select("select * from hr_salary_level where SalaryID='ZA105'");
                $salary_level = [];
                foreach ($salary_levels as $key=>$it){
                    $Express = $it['Express'];
                    if(strpos($Express,"(1,") !== false){ 
                        // echo "{$it['ID']}包含\n";
                        $salary_level[0] = $it;
                    }
                    if(strpos($Express,",1,") !== false){ 
                        // echo "{$it['ID']}包含\n";
                        $salary_level[0] = $it;
                    }
                    if(strpos($Express,",1)") !== false){ 
                        // echo "{$it['ID']}包含\n";
                        $salary_level[0] = $it;
                    }
                    if(strpos($Express,"(1)") !== false){ 
                        // echo "{$it['ID']}包含\n";
                        $salary_level[0] = $it;
                    }
                }
