Strict PHP

Installation

composer require nusje2000/strict-php

Why?

This package was created because of the way the default php functions behave. A lot of functions return types that are not logical. This package wraps these functions and adds correct error handling and typing to these functions.

Functions

File functions

exists (replaces is_file)

To check if a file exists, you can use File::exists():

use Nusje2000\StrictPhp\File;

File::exists('path/to/file.txt');

getContents (replaces file_get_contents)

To retrieve contents from a file, you can use File::getContents(). This function will return the contents and if not possible, an exception will be thrown.

use Nusje2000\StrictPhp\File;

File::getContents('path/to/file.txt');

putContents (replaces file_put_contents)

To write contents to a file, you can use File::putContents(). This function will always return the amount of bytes written and if not possible, an exception will be thrown.

use Nusje2000\StrictPhp\File;

File::putContents('path/to/file.txt', 'contents');

Directory functions

exists (replaces is_dir)

To check if a directory exists, you can use Directory::exists().

use Nusje2000\StrictPhp\Directory;

Directory::exists('path/to/file.txt');

Json functions

encode (replaces json_encode)

To encode a variable into json, you can use Json::encode(). This will always return the encoded string. If the encoding fails, an exception will be thrown.

use Nusje2000\StrictPhp\Json;

Json::encode(['key' => 'value']);

decode (replaces json_decode)

To decode a json formatted string, you can use Json::decode(). This function has multiple return types.

use Nusje2000\StrictPhp\Json;

Json::decode('"some-valid-json"');

decodeToObject (replaces json_decode)

If an object is expected as return type, decodeToObject can be used to both decode and assert that the output is an object. If the output is not an instance of stdClass, an exception will be thrown.

use Nusje2000\StrictPhp\Json;

Json::decodeToObject('{"key": "value"}'); // stdClass { $key = 'value' }

decodeToArray (replaces json_decode)

If an array is expected as return type, decodeToArray can be used to both decode and assert that the output is an array. If the output is not an array, an exception will be thrown.

use Nusje2000\StrictPhp\Json;

Json::decodeToArray('["value 1", "value 2", "value 3"]'); // ['value 1', 'value 2', 'value 3']
Json::decodeToArray('{"key": "value"}'); // ['key' => 'value']
