Call a stored procedure with the same name using PDO - php

Question

I have two stored procedures in my database Postgres, both have the same name but the difference are the parameters.
procedure1(::string, ::integer, ::string, ::integer)
procedure1(::string, ::integer, ::integer)
In PDO doing bindParam correct, is coming STR, INT, INT but the prepere always performs procedure1.
How do I get him to understand what I call the procedure2?
Some information for more help? I clear? thanks
EDIT ===
...
$bounds = null; // forced for debug
if(!is_null($bounds)){
$query = "SELECT procedure1(:name, :domain, :geo, :userid)";
$stmt = $db->prepare($query);
$stmt->bindParam('name', $name, PDO::PARAM_STR);
$stmt->bindParam('domain', $idDomain, PDO::PARAM_INT);
$stmt->bindParam('geo', $geoString, PDO::PARAM_STR);
$stmt->bindParam('userid', $userId, PDO::PARAM_INT);
}else{
$query = "SELECT procedure1(:name, :domain, :userid)";
$stmt = $db->prepare($query);
$stmt->bindParam('name', $name, PDO::PARAM_STR);
$stmt->bindParam('domain', $idDomain, PDO::PARAM_INT);
$stmt->bindParam('userid', $userId, PDO::PARAM_INT);
}
$result = $stmt->execute();
...
The error it gives is that he is running a procedure that requires four parameters

Try changing your $query statements to explicitly tell PDO the types, and to avoid extra code switch to bindValue (PDO uses the PARAM flags to format SQL, not to cast data types):
$bounds = null; // forced for debug
if(!is_null($bounds)){
$query = "SELECT procedure1(:name::VARCHAR, :domain::INTEGER, :geo::VARCHAR, :userid::INTEGER)";
$stmt = $db->prepare($query);
$stmt->bindValue('name', $name);
$stmt->bindValue('domain', $idDomain);
$stmt->bindValue('geo', $geoString);
$stmt->bindValue('userid', $userId);
}else{
$query = "SELECT procedure1(:name::VARCHAR, :domain::INTEGER, :userid::INTEGER)";
$stmt = $db->prepare($query);
$stmt->bindValue('name', $name);
$stmt->bindValue('domain', $idDomain);
$stmt->bindValue('userid', $userId);
}
$result = $stmt->execute();
