Getting Started

You can simply use the Parser class to parser the the json string.

use JsonApiParser/Parser;
$parser =new Parser($jsonString);
try to parse a json string

the ParserException to catch all exception

use JsonApiParser\Parser;
use JsonApiParser\Exceptions\ParserException;

try{
$parser = new Parser($jsonString);
}catch(ParserException $e){
echo $e->getMessage();
}

a very complex example

suppose we have receive this json response from our client

            }
        }
    ]
}

And we wanted to print all the information by nested loop

use JsonApiParser\Parser; 

$parser = new Parser($jsonString); 
//To print a version
echo $parser->version();
//Whole meta object
print_r($parser->meta());
//Single meta object
echo $parser->meta()->total;

//To get whole links object
print_r($parser->links());
//To get a single link
echo $parser->links()->self;

//prepare included relational data
$included = $parser->included();
//main data block
$articles = $parser->data(); 

foreach ($articles as $article) { 
    //print the article type
    echo $article->type();
    //print the article id
    echo $article->id();
    
    //To check if any specific key exist
    var_dump($item->contain('attributes', 'title'));
    
    //to print an item attribute
    echo $item->attribute()->title;
    
    //Fetch a relationship object by relationship name
    $comments = $item->relationships("comments"); 
    
    //To print all the comments
    foreach ($comments->data() as $comment) { 
        //print the id
        echo $comment->id();
        //Fetch the relational data from included
        $commentItem = $comment->comments();

        //print it's attribute
        echo $commentItem->attribute()->body;
        
        $authors = $commentItem->relationships("author");
        foreach($authors->data() as $author){
            //author id
            echo $author->id();

            //to print the author attribute item
            echo $author->people()->attribute()->twitter;
        }
                
     }

}
