Data filtering and validation¶

Data filtering¶

Class \Comodojo\Foundation\Validation\DataFilter provides some useful methods to filter data extending (or shortcutting) php funcs.

Included methods are:

filterInteger: conditional int filter from ($min, $max, $default)
filterPort: TCP/UDP port filtering
filterBoolean: boolean filter

Usage example:

<?php

$https = 443;
$invalid_port = 10000000;
$default = 8080;

var_dump(\Comodojo\Foundation\Validation\DataFilter::filterPort($https, $default));

var_dump(\Comodojo\Foundation\Validation\DataFilter::filterPort($invalid_port, $default));

It returns:

int(443)

int(8080)

Data validation¶

Class \Comodojo\Foundation\Validation\DataValidation provides methods to validate data types, optionally applying a custom filter on value itself.

Validation can be invoked via validate methods, that accepts input data, data type and filter, or using specific validation methods:

validateString
validateBoolean
validateInteger
validateNumeric
validateFloat
validateJson
validateSerialized
validateArray
validateStruct
validateDatetimeIso8601
validateBase64
validateNull
validateTimestamp

Usage example:

<?php

$http = 80;
$https = 443;

$filter = function(int $data) {
    // check if port 80
    return $data === 80;
};

var_dump(\Comodojo\Foundation\Validation\DataValidation::validateInteger($http, $filter));

var_dump(\Comodojo\Foundation\Validation\DataValidation::validateInteger($https, $filter));

It returns:

bool(true)

bool(false)
