how to json_encode 'php array'

Question

i have the following array like this :

{"label":"label1","data":[[10,55],[15,32],[16,49]]}
{"label":"label","data":[[10,55],[15,32],[16,49]]} 

how to get string character (,) beetween {"label":"label1","data":[[10,55],[15,32],[16,49]]} and {"label":"label2","data":[[10,55],[15,32],[16,49]]} result like this..

{"label":"label1","data":[[10,55],[15,32],[16,49]]},
{"label":"label","data":[[10,55],[15,32],[16,49]]} 

Code

while($row = mysql_fetch_assoc($result))
{ 
 $int = $row['SC'];
 $join = intval($int);
 $int2 = $row['jam'];
 $join2 = intval($int2);
 $dataset1[] = array($join2,$join);
}
for ($i=0; $i <2 ; $i++) { 
$dataset = array(label => label1, data => $dataset1);
$final = json_encode($dataset);
echo $final;

• Nabil Kadimi: Using mysql_fetch_assoc! Then read this.
• Mike 'Pomax' Kamermans: but really, using mysqli_..., because msql_... has been removed from PHP.
• Brad Christie: Sure you don't mean $dataset1[$i] in that for loop? Or are you seriously dumping the same thing over and over?
• James: This code only produces one {label....} object. How you would join two or more of them depends on how you generate the others.
• Barmar: What is $label = label doing? Should that be $label[] = $row['label']?

Answer 1

You need to put everything into another array:

$dataset = array();
foreach ($dataset1 as $d) {
 $dataset[] = array('label' => $label, 'data' => $d);
}
$final = json_encode($dataset);
echo $final;

This should output:

[{"label":"label1","data":[[10,55],[15,32],[16,49]]},
 {"label":"label","data":[[10,55],[15,32],[16,49]]}]
