Documentation / Basic Type Converter

Introduction

The BasicTypeConverter converts using PHP´s internal casting, with a few special cases.

• If input is an Object and output type is Array or Object, get_object_vars() is used to extract object variables.
• If input is an Array or Object and output type is String, get_debug_type() is used to create string representation

Using the converter

$converter = new BasicTypeConverter();

// Convert to same type as input
$converter->canTransform($input); // -> bool
$converter->transform($input); // -> converted output

// Convert to other types
$converter->canTransform($input, Type::STRING); // -> bool
$converter->transform($input, Type::STRING); // -> string output
$converter->canTransform($input, Type::ARRAY); // -> bool
$converter->transform($input, Type:: ARRAY); // -> array output

// Default type mapping
$converter = new BasicTypeConverter([
  Type::INTEGER => Type::STRING,
  Type::OBJECT => Type::ARRAY,
]);
$converter->transform(123); // -> string output
$converter->transform($myObject); // -> array output

Type conversion examples

If type is not specified, the converter will keep original type.

Input	Type: Array	Type: Boolean	Type: Integer	Type: Null	Type: Number	Type: Object	Type: String
"A string"	[0: "A string"]	true	0	null	0.0	{$scalar: "A string"}	"A string"
""	[0: ""]	false	0	null	0.0	{$scalar: ""}	""
["A string"]	[0: "A string"]	true	1	null	1.0	{$0: "A string"}	array
[]	[]	false	0	null	0.0	{}	array
