安装

composer require imj/filter

基本用法

过滤字符串

use Imj\Filter

$str = ' str';
echo Filter::string($str); // str

$str = 'abcdefg';
echo Filter::string($str, ['length'=>2]); // ab

$str = 'abc';
echo Filter::string($str, ['regex'=>"/\d+/"]); // null

过滤 int/uint/float/ufloat

use Imj\Filter

$int = '10';
echo Filter::int($int, ['max'=>11, 'min'=>8]); // 10

$int = '10';
echo Filter::int($int, ['max'=>8]); // 8

$int = '10';
echo Filter::int($int, ['min'=>11]); // 11

$int = '10';
echo Filter::int($int, ['min'=>11, 'default'=>100]); // 100

$int = -1;
echo Filter::uint($int, ['default'=>100]);

// uint/float/ufloat method is the same

通过枚举过滤

use Imj\Filter

$v = 'foo';
echo Filter::enum($v, ['enum'=>['foo', 'bar']]); // foo

$v = 'baz';
echo Filter::enum($v, ['enum'=>['foo', 'bar']]); // foo

$v = 'baz';
echo Filter::enum($v, ['enum'=>['foo', 'bar'], 'default'=>'fbb']); //fbb

通过枚举键过滤

use Imj\Filter

$enum = [
  'a' => 'foo',
  'b' => 'bar',
  'c' => 'baz'
];

$v = 'a';
echo Filter::enumByKey($v, ['enum'=>$enum]); // foo

$v = 'd';
echo Filter::enumByKey($v, ['enum'=>$enum]); // foo

$v = 'd';
echo Filter::enumByKey($v, ['enum'=>$enum, 'default_key'=>'b']); // bar

$v = 'd';
echo Filter::enumByKey($v, ['enum'=>$enum, 'default'=>'baz']); // baz

$v = 'd';
echo Filter::enumByKey($v, ['enum'=>$enum, 'default_key'=>'b', 'enum_key' => true]); // b

过滤 JSON

use Imj\Filter

$arr = ['foo'=>1];
$v = json_encode($arr);
var_dump(Filter::json($v, ['json_assoc'=>true])); // ['foo'=>1]

$arr = ['foo'=>'1', 'bar'=>'2'];
$v = json_encode($arr);
var_dump(Filter::json($v, ['json_assoc'=>true, 'json_schema'=>['foo' => [Filter::UINT_TYPE]]])); // ['foo'=>1, 'bar'=>'2']

此外，您还可以使用 validate 方法，效果相同。

use Imj\Filter

$str = 'abcdefg';
echo Filter::validate($str, Filter::STRING_TYPE, ['length'=>2]); // ab
// ...

第二个参数表示变量类型，可以是

Filter::STRING_TYPE
Filter::INT_TYPE
Filter::UINT_TYPE
Filter::FLOAT_TYPE
Filter::UFLOAT_TYPE
Filter::ENUM_TYPE
Filter::ENUM_KEYS_TYPE
Filter::JSON_TYPE
Filter::NONE_TYPE
