Hi everyone,
i have a page that uses jquery ajax to get json from another page. However, instead of the ajax using sucess, it goes directly to error. I have a debug on the error to see what is the issue and i get "Parsing JSON Request failed."

page 1.php

$("#validate").click(function() {
    var tags = $("#coc_tag").val();
    var type = $("#type").val();
    var cleantag = tags.replace(/#/, "%23");

    switch(type) {
        case 'clan':
            $.ajax({
                url: "/coc/mirror.php?tag="+cleantag+"&type="+type,
                method: "GET",
                //dataType: "json",
                cache: false,
                success: function(data, textStatus){
                    //for testing.
                    alert("good");
                    $.each(data,function( key, value ) {
                        alert( key + ": " + value );
                    })
                },
                error:function(x,e) {
                    if (x.status==0) {
                        alert('You are offline!!\n Please Check Your Network.');
                    } else if(x.status==404) {
                        alert('Requested URL not found.');
                    } else if(x.status==500) {
                        alert('Internel Server Error.');
                    } else if(e=='parsererror') {
                        alert('Error.\nParsing JSON Request failed.');
                    } else if(e=='timeout'){
                        alert('Request Time out.');
                    } else {
                        alert('Unknow Error.\n'+x.responseText);
                    }
                }
            });
        break;
    }
});

here is the php page the outputs the json.
mirror.php

<?php
header('Content-type: application/json');
// extra curl stuff that i took out
$headr = array();
$headr[] = "Accept: application/json";
$headr[] = "Authorization: Bearer ".$token;

curl_setopt($ch, CURLOPT_HTTPHEADER, $headr);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

$res = curl_exec($ch);
$data = json_decode($res, true);

$items = $data["items"];

class item {
    public $tag = "";
}

$test = new item();
foreach($items as $item) {
    $test->tag = $item["tag"];
    echo json_encode($test);
}
curl_close($ch);
?>

The output looks like this

{"tag":"#VGLVGVVJ"}{"tag":"#Y0G8PC2G"}{"tag":"#90UVCJUU"}{"tag":"#LG9L8GJG"}{"tag":"#J80R2VLJ"}{"tag":"#9PP298LR"}{"tag":"#Q0JYV8JU"}{"tag":"#9JY2U2YY"}{"tag":"#LPUUG2Y9"}{"tag":"#GL9929UC"}{"tag":"#PG0QQJ09"}{"tag":"#9PLR09G0"}{"tag":"#GCJPQ92Y"}{"tag":"#UC00RCLJ"}{"tag":"#2LR8UVLJ0"}{"tag":"#RVUYGCPV"}{"tag":"#2LJLQGYGG"}{"tag":"#RQ22PJYC"}{"tag":"#PP0P9VUL"}{"tag":"#8RVCV0RV"}{"tag":"#QL88L9CJ"}{"tag":"#RUCLLUV"}{"tag":"#2Q0PQCPV"}{"tag":"#RYLJJU02"}{"tag":"#GVGJLQU9"}{"tag":"#L8VLQGC9"}{"tag":"#2288P98Q8"}{"tag":"#2CG22U002"}{"tag":"#VGJQYQQ9"}{"tag":"#2ULCPY2G0"}{"tag":"#229GP9C09"}{"tag":"#82RPULG2"}{"tag":"#VU82QUCY"}{"tag":"#202JCRL9"}{"tag":"#VCR8PY2V"}{"tag":"#8YLC2LJCR"}{"tag":"#GUQJQU90"}{"tag":"#RPQ0U2Y0"}{"tag":"#2LLGC8C8V"}{"tag":"#22CPJRPPQ"}{"tag":"#UCUL0RR0"}{"tag":"#2LC82CL8"}{"tag":"#2RJQ9P28C"}{"tag":"#2QPCYY9U"}{"tag":"#P2VU8YG0"}{"tag":"#20RGCLCL"}{"tag":"#2YJG2R88C"}

Again, im getting the error trigger on the jQuery ajax.

Not sure I understand. Are you getting data from a non-ajax run of the php script? If you had an ajax error, then you wouldn't get the data.

Anyway - this isn't valid json as you are returning multiple objects. If you added all the objects to an array that should work - then you can json_encode that and use the dataType: "json" in your ajax setup.

There must be a simpler way of getting the data. A simple data structure to pass back may be:

["#VGLVGVVJ","#Y0G8PC2G","#90UVCJUU","#LG9L8GJG","#J80R2VLJ","#9PP298LR","#Q0JYV8JU","#9JY2U2YY","#LPUUG2Y9","#GL9929UC","#PG0QQJ09","#9PLR09G0","#GCJPQ92Y","#UC00RCLJ","#2LR8UVLJ0","#RVUYGCPV","#2LJLQGYGG","#RQ22PJYC","#PP0P9VUL","#8RVCV0RV","#QL88L9CJ","#RUCLLUV","#2Q0PQCPV","#RYLJJU02","#GVGJLQU9","#L8VLQGC9","#2288P98Q8","#2CG22U002","#VGJQYQQ9","#2ULCPY2G0","#229GP9C09","#82RPULG2","#VU82QUCY","#202JCRL9","#VCR8PY2V","#8YLC2LJCR","#GUQJQU90","#RPQ0U2Y0","#2LLGC8C8V","#22CPJRPPQ","#UCUL0RR0","#2LC82CL8","#2RJQ9P28C","#2QPCYY9U","#P2VU8YG0","#20RGCLCL","#2YJG2R88C"]

That is, a simple array of what looks like id values.

Maybe...

$data = $data = json_decode($res, true);
$array = array_column($data['items'], 'tag');
echo json_encode($array);

No need for loops.

Just want to get the name and tag of each member and return them with json_encode back to page1.php.
i re-added the dataType: "json", and with your answer i was able to get a success response. Thanks alot on that.
I have been looking about about trying to loop through multidimenstional associative array, but without using foreach - from my level of knowledge - i wont be able to return them all without actually having the build the structure.
crude example:
echo "{"
for($i=0;$i<51;$i++)
echo "\"tag\"=>".$array = array_column($data['items'], 'tag').",";
echo "}";

Just want to say thanks diafol. Given the above output from above, i will work on this and post what ever i come up with.
i guess for night now, i can use each $k=>$v, but im still gonna tinker around. Thanks for the reply.

Hi MIke - this simple 4-line function may be useful:

Shove in your json_decoded array (items level) and a mask array that has a list of the top level fields you need. This could be done just as easily with a individual items in a foreach loop, but intersect helps to simplify the code - may be marginally slower though.

//Simple top-level retriever

function cherryPick(Array $dataArray, Array $maskArray)
{
    $result = [];
    $myMask = array_flip($maskArray);
    foreach($dataArray as $item) $result[] = array_intersect_key($item, $myMask);
    return $result;
}

$mask = ['name', 'tag', 'trophies'];

echo "<pre>";
print_r(cherryPick($data['items'], $mask));
