检查字符串是否以

Question

在PHP中,我有一个国家电话代码列表.例如:US 1,Egypt 20 ....
我需要检查给定的字符串是否以00[ANY NUMBER FROM THE LIST].
我怎样才能实现这一点并返回国家/地区代码？

Answer 1

$codes = array(1 => 'US', 20 => 'Egypt');
$phone = '002087458454';

foreach ($codes as $code => $country) {
  if (strpos($phone, "00$code") === 0)
    break;
}

echo $code;    // 20
echo $country; // Egypt
