使用此查詢'$ sql =「SELECT id FROM countries WHERE country_code IN（LEFT（$ number，3），LEFT（$ number，2），LEFT（$ number，1），0）」' – Gaurav

$ sql =從country_code i的國家中選擇id （LEFT（$ number，3），LEFT（$ number，2），LEFT（$ number，1），0）; – Alok

@Gaurav它會像魅力一樣工作 –

$sql = "SELECT id 
FROM countries 
WHERE country_code = LEFT($number,3) 
    OR country_code = LEFT($number,2) 
    OR country_code = LEFT($number,1) 
    OR country_code = 0";

取決於你，如果你想嚴格的再使用條件，如果沒有則OR

$sql = "SELECT id FROM countries WHERE country_code = LEFT($number,3) OR 
     country_code = LEFT($number,2) OR country_code = LEFT($number,1) OR 
     country_code =0 ";

// if you want want result from table for all condition true than write 
    //below query 
    $sql= "SELECT id 
      FROM countries 
      WHERE country_code = LEFT($number,3) 
      AND country_code = LEFT($number,2) 
      AND country_code = LEFT($number,1) 
      AND country_code = LEFT($number,0)" 

    // if you want result for OR condition 

    $sql= "SELECT id 
      FROM countries 
      WHERE country_code = LEFT($number,3) 
      OR country_code = LEFT($number,2) 
      OR country_code = LEFT($number,1) 
      OR country_code = LEFT($number,0)"
