PHP implements custom function sharing that hides the middle four digits of a mobile phone number with asterisks (*)

The code is as follows:

Method 1：
function hidtel($phone){
$IsWhat = preg_match('/(0[0-9]{2,3}[-]?[2-9][0-9]{6,7}[-]?[0-9]?)/ i',$phone); //Landline phone
If($IsWhat == 1){
return preg_replace('/(0[0-9]{2,3}[-]?[2-9])[0-9]{3,4}([0-9]{3}[-]? [0-9]?)/i','$1****$2',$phone);
}else{
return preg_replace('/(1[358]{1}[0-9])[0-9]{4}([0-9]{4})/i','$1****$2', $phone);
}
}

Method 2:
$num = "13966778888"
$str = substr_replace($num,'****',3,4);

Example:

The code is as follows:

$phonenum = "13966778888";
echo hidtel($phonenum);

Final output: 139****8888
