我如何获得数组结果的值？

Question

I'm new and I work in php. I have a problem, I have this "array" result from php script (this array was extracted with php of a html page):

Array ( [0] => {"autostart": false,"controls": true,"flashplayer": "/jwplayer7/jwplayer.flash.swf","image": "I NEED THIS", ga: {}, "mute": false, "ph": 1, "preload": "none", "primary": "html", "repeat": false, "skin": { "name": "tube" }, "stagevideo": true, "stretching": "uniform", "visualplaylist": true, "width": "100%", "aspectratio": "16:9", "provider": 'http', "startparam": "start", tracks: [{"file":"I WANT THIS","kind":"thumbnails"}], "sources": [{"file":"I NEED THIS","label":"480p"},{"file":"I NEED THIS","label":"720p"},"I WANT THIS"] ,"logo": {"logoBar": "I NEED THIS", "target": "blank","link": ""},"displaydescription": false,"displaytitle": false , "abouttext": "RapTu Player", "aboutlink": "" } )

I only need the values from image:, sources:[{"file";}} but I can't get the values, nothing, I try with javascript:

var str = '<?php echo $jw; ?>';
var json = JSON.parse(str);
var parse = $.parseJSON(file);

$jw is the variable of the array, and I don't have any result, nothing is printed. Could you help me? (Sorry for my english).

Upgrade: I resolved it using:

object = [<?php echo $jw; ?>]
for(f=0;f<object.length;f++){
}

Thanks everybody!

Answer 1

if you want doing that. Then use

var json = '<?php echo json_encode($jw); ?>';

and in json variable you have json from array

or if you only sources you can use

var json = '<?php echo json_encode($jw[0]["sources"]); ?>';

but only work with first element in array $jw
