Why do you need to validate phone number using php ? 为什么您需要使用php验证电话号码？ You can do it using JS as shown below. 您可以使用JS进行操作，如下所示。
if (/^\+[-0-9]{6,20}$/.test(phoneNumber) == false) {
alert('Wrong Phone Number format. Only numbers,+ and - are allowed. Format: \<Country Code\>\<Phone number\> Eg: +9199999999, +1-105-893-9334 etc');
return;
}

According to comments and example phone number that you given, this code will validating number of digits and first two numbers of your country, i just replaced + with 0 , for sure they won't enter plus. 根据您提供的注释和示例电话号码，此代码将验证您所在国家的数字位数和前两个数字，我只是将+替换为0 ，以确保它们不会输入加号。
$tel = '091-9869123456';
if(preg_match("/^[0-9]{3}-[0-9]{10}$/", $tel)) {
echo "valid";
} else {
echo "invalid";
}
Now for more validating need to check country code: 现在，为了进行更多验证，需要检查国家代码：
if(substr($tel, 0, 3) == '091'){
echo "valid";
} else {
echo "invalid, it should start with 091";
}
Or you do this with same preg_match like this: 或者您使用相同的preg_match执行此操作，如下所示：
if(preg_match("/^[091]{3}-[0-9]{10}$/", $tel)) {
echo "valid";
} else {
echo "invalid";
}

Sorry to answer an old post. 很抱歉回答一个旧帖子。
However, you can check if the number exists by calling a web service. 但是，您可以通过调用Web服务来检查号码是否存在。 In this case, I found numverify.com, allowing to verify if a phone number exists. 在这种情况下，我找到了numverify.com，可以验证电话号码是否存在。
After creating a free account (allows you to make 250 requests each month), you can invoke the following basic code in PHP: 创建免费帐户（允许您每月发出250个请求）后，可以在PHP中调用以下基本代码：
// set API Access Key
$access_key = 'YOUR_ACCESS_KEY';
// set phone number
$phone_number = '14158586273';
// Initialize CURL:
$ch = curl_init('http://apilayer.net/api/validate?access_key='.$access_key.'&number='.$phone_number.'');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Store the data:
$json = curl_exec($ch);
curl_close($ch);
// Decode JSON response:
$validationResult = json_decode($json, true);
I have no idea if this is reliable, but it worked with my phone number and even retrieved the company carrier. 我不知道这是否可靠，但是可以使用我的电话号码，甚至可以找回公司运营商。
