Remove the last charater from string which is generated in loop

Question

Believe me, I have tried everything that is there in stack overflow!

So, I got this JSON -

$j={
    "itempicture": [
        {
            "status": "3"
        },
        {
            "ItemCode": "001",
            "ItemImage": "image1",
            "ItemCategory": "shirt",
            "ShowOnPOS": "Yes",
            "LastModifiedOn": "2018-06-02 11:53:57"
        },
        {
            "ItemCode": "002",
            "ItemImage": "image2",
            "ItemCategory": "shirt",
            "ShowOnPOS": "Yes",
            "LastModifiedOn": "2018-06-02 11:53:57"
        }
    ]
}

and i am accessing it like this -

$jo = json_decode($j);
for($i = 1; $i < count($jo->itempicture); $i++) {
    foreach($jo->itempicture[$i] as $prop=>$val) {
        echo $val.",";
    }
    echo '<br>';
}

and I'm getting this output -

001,image1,shirt,Yes,2018-06-02 11:53:57,
002,image2,shirt,Yes,2018-06-02 11:53:57,

The main prob with this output is the "," at the last. I am unable to remove it!

Tried everything - This - Remove the last character from string

with substr, rtrim, implode... EVERYTHING!

It's not working!

Here is the solution

$j='{"itempicture":[
{
    "status":"3"
},
{
    "ItemCode":"001",
    "ItemImage":"image1",
    "ItemCategory":"shirt",
    "ShowOnPOS":"Yes",
    "LastModifiedOn":"2018-06-02 11:53:57"
},
{
    "ItemCode":"002",
    "ItemImage":"image2",
    "ItemCategory":"shirt",
    "ShowOnPOS":"Yes",
    "LastModifiedOn":"2018-06-02 11:53:57"
}
]
}';
$jo=json_decode($j);
$edata = '';
for($i=1;$i<count($jo->itempicture);$i++){
    $data = '';
    foreach($jo->itempicture[$i] as $prop=>$val){
        $data .= $val.",";
    }
    $edata .= rtrim($data, ",");
    $edata .='<br/>';
}

echo "<pre>";
print_r($edata);
echo "</pre>";
