在PHP中生成JSON时,可以通过以下方法减少冗余:
$data = [
'name' => 'John',
'age' => 30,
'address' => [
'street' => 'Main St',
'city' => 'New York',
'state' => 'NY',
'zip' => '10001'
]
];
array_filter()
函数过滤掉不需要的数据。$data = [
'name' => 'John',
'age' => 30,
'address' => [
'street' => 'Main St',
'city' => 'New York',
'state' => 'NY',
'zip' => '10001'
]
];
$filtered_data = array_filter($data, function ($value) {
return !is_null($value);
});
json_encode()
的JSON_UNESCAPED_UNICODE
选项:在将数据转换为JSON时,可以使用json_encode()
函数的JSON_UNESCAPED_UNICODE
选项来避免对Unicode字符进行转义,从而减少输出中的冗余。$data = [
'name' => 'John',
'age' => 30,
'address' => [
'street' => 'Main St',
'city' => 'New York',
'state' => 'NY',
'zip' => '10001'
]
];
$json_data = json_encode($filtered_data, JSON_UNESCAPED_UNICODE);
class Address {
public $street;
public $city;
public $state;
public $zip;
}
$data = [
'name' => 'John',
'age' => 30,
'address' => new Address([
'street' => 'Main St',
'city' => 'New York',
'state' => 'NY',
'zip' => '10001'
])
];
遵循这些建议,您可以在PHP中生成更简洁、可读性更强的JSON数据。
