$_bindings protected
arrayArray containing a list of bound values to the conditions on this object. Each array entry is another array structure containing the actual bound value, its type and the placeholder it is bound to.
-
$_bindingsCount protected
intA counter of the number of parameters bound in this expression object
Method Summary
-
attachTo() public
Binds all the stored values in this object to the passed statement.
-
bind() public
Associates a query placeholder to a value and a type
-
bindings() public
Returns all values bound to this expression object at this nesting level. Subexpression bound values will not be returned with this function.
-
generateManyNamed() public
Creates unique named placeholders for each of the passed values and binds them with the specified type.
-
placeholder() public
Creates a unique placeholder name if the token provided does not start with ":" otherwise, it will return the same string and internally increment the number of placeholders generated by this object.
-
reset() public
Clears any bindings that were previously registered
-
resetCount() public
Resets the bindings count without clearing previously bound values
