The idea behind this library is to allow the access through
`config.port` dot notation to object data.
Why?
My main problem was when accessing API data., (*2)
{
"hits":{
"products": [
{
"name": "Shoe"
}
]
}
}
Imagine this is the result from an API. Usually to be sure that the data is what I want I'm gonna need to do:, (*3)
<?php
$result = r(); // imagine this is the result from an API with the json message abobe
if(is_object($result) && property_exists($result, 'hits')){
if(is_object($result->hits) && property_exists($result->hits, 'products')){
$whatiwant = $result->hits->products;
}
}
This is really time consuming. I just needed a way to do something like:, (*4)
<?php
$d = \Alr\ObjectDotNotation\Data::load(r());
$whatiwant = $d->get('hits.products');
Note: In PHP7 you can just use $var = $something ?? $something2; but if you need to do this dynamically it becomes harder to do., (*5)
Demo
You can try a demo here, (*6)
Installation
Requires composer and PHP5.6+, (*7)
$ composer require alrik11es/object-dot-notation, (*8)
Usage
When the property is not found a null will be returned., (*9)
Take this object as example:, (*10)
{
"config": {
"port": "1234",
"url": "testurl.com"
}
}
Then:, (*11)
<?php
$d = \Alr\ObjectDotNotation\Data::load($mixed);
echo $d->get('config.port'); // 1234
echo $d->{'config.port'};
echo $d->config; // ['port'=>1234 ...]
Array and array search
For other kind of uses you're gonna need to get a position of an array or search
and get the first value of array., (*12)
Take this object as example:, (*13)
{
"config": [{
"port": "80",
"url": "aurl.com"
},{
"port": "90",
"url": "burl.com"
}]
}
You can use this way to access the information:, (*14)
<?php
$d = \Alr\ObjectDotNotation\Data::load($mixed);
echo $d->get('config[0].port'); // 80
echo $d->{'config[port=90|first].url'}; // burl.com
Filters
You can use filters for the array selection process., (*15)
[port=90|first], (*16)
IMPORTANT NOTE: Actually you can only use |first filter, use it always because it's going to be needed on future versions to avoid compatibility problems., (*17)
Advanced filters
TODO, (*18)
