Wie zu Lesen json-Eigenschaften mit Hilfe von PHP

Wie pid und Stile Attribut aus folgenden json-Daten mit minimum Schleife in php

{"general":{"note":{"display":false}},"elements":{"the-1":{"index":1,"src":"shirt1.png","pid":"pid-3563130","angle":0,"styles":"background:transparent;top:51.80000305175781px;left:122px;width:80px;height:80px;","background":"transparent","pos":{"top":51.80000305175781,"left":122},"size":{"width":80,"height":80},"details":{"other":""}},"the-2":{"index":2,"src":"shirt2.png","pid":"pid-132002","angle":0,"styles":"background:transparent;top:44.80000305175781px;left:155px;width:80px;height:80px;","background":"transparent","pos":{"top":44.80000305175781,"left":155},"size":{"width":80,"height":80},"details":{"other":""}}}}

    verwenden json_decode-Funktion in PHP zu bekommen assosiative array.

    <?php
    $myJson = '{"general":{"note":{"display":false}},"elements":{"the-1":{"index":1,"src":"shirt1.png","pid":"pid-3563130","angle":0,"styles":"background:transparent;top:51.80000305175781px;left:122px;width:80px;height:80px;","background":"transparent","pos":{"top":51.80000305175781,"left":122},"size":{"width":80,"height":80},"details":{"other":""}},"the-2":{"index":2,"src":"shirt2.png","pid":"pid-132002","angle":0,"styles":"background:transparent;top:44.80000305175781px;left:155px;width:80px;height:80px;","background":"transparent","pos":{"top":44.80000305175781,"left":155},"size":{"width":80,"height":80},"details":{"other":""}}}}';  
    $myArray = json_decode($myJson,true);
    $myInnerArray = $myArray['elements'];
    $styles = array();
    foreach($myInnerArray as $element)
       $styles[] = $element['styles'];
    print_r($styles);

    ?>

    PHP hat große Fähigkeiten json zu behandeln.

    Nehmen wir an, die JSON-string, den Sie oben gepostet habe ist gespeichert in einer PHP-variable $myJSON.

    So können wir leicht speichern ein assoziatives array mit diesen Werten in $myJSONArray etwa so:

    $myJSONArray = json_decode( $myJSON, true );

    So, jetzt haben wir einfach eine Schleife durch:

    foreach( $myJSONArray['elements'] as $arr => $key )
     echo( "A PID: " . $key['pid'] . "\n" );

    Sehen Sie es in Aktion auf Codepad.
