How to retrieve values from multilevel json - php

Question

Im trying to get the values from the various sections of this json entry.
{
"gallery_show": "1",
"gallery": {
"path": ["images\/slide2.jpg", "images\/slide1.jpg", "images\/slide2.jpg", "images\/slide1.jpg", "images\/slide2.jpg", "images\/slide1.jpg"],
"title": ["", "", "", "", "", ""],
"caption": ["", "", "", "", "", ""],
"thumb": ["\/admin\/cache\/thumbs_200x150\/slide2_200x150.jpg",
"\/admin\/cache\/thumbs_200x150\/slide1_200x150.jpg",
"\/admin\/cache\/thumbs_200x150\/slide2_200x150.jpg",
"\/admin\/cache\/thumbs_200x150\/slide1_200x150.jpg",
"\/admin\/cache\/thumbs_200x150\/slide2_200x150.jpg",
"\/admin\/cache\/thumbs_200x150\/slide1_200x150.jpg"]
},
"videos_show": "1",
"videos": {
"title": ["Arnie", "Arnie", "Arnie", "Arnie", "Arnie"],
"sharelink": ["http:\/\/youtu.be\/7kTz6MVrBlY", "http:\/\/youtu.be\/7kTz6MVrBlY", "http:\/\/youtu.be\/7kTz6MVrBlY", "http:\/\/youtu.be\/7kTz6MVrBlY", "http:\/\/youtu.be\/7kTz6MVrBlY"]
},
"attachments_show": "1",
"attachments": {
"path": ["images\/slide2.jpg", "images\/slide1.jpg"],
"title": ["Attchment", "Attchment"],
"caption": ["Attachment Description", "Attachment Description"]
},
"links_show": "1",
"links": {
"title": ["Link1", "Link2"],
"httplink": ["http:\/\/www.mydomain.com", "http:\/\/www.mydomain.com"],
"targetlink": ["_blank", "_blank"]
}
}
If i use this method
$entries= json_decode($this->item->entries);
and then i echo this
echo $entries->gallery_show;
I get the desired result = 1
But how do i now get the things beneath it if gallery_show=1 and display them as values i can use inside my php?
Any help for this old brain would be much appreciated.
Cheers in advance

You could do somewhat like this...
$arr = json_decode($json);
foreach($arr as $k=>$v)
{
if($k=='gallery_show' && $v==1)
{
foreach($arr->gallery->path as $path)
{
echo "<img src=$path />";
}
break;
}
}

Code update..
$arr = json_decode($json);
$i=0;
foreach($arr as $k=>$v)
{
if($k=='gallery_show' && $v==1)
{
foreach($arr->gallery as $gall)
{
echo "Title :".$arr->gallery->title[$i]."<br/>";
echo "Caption :".$arr->gallery->caption[$i]."<br/>";
echo "Thumbnail :".$arr->gallery->thumb[$i]."<br>";
echo "<img src=".$arr->gallery->path[$i]." /><br>";
$i++;
}
break;
}
}
