Parsing decoded JSON in PHP - php

Question

I have managed to decode some JSON in PHP successfully (not as painful as I thought), but it's been such a long time since I've done any real PHP, my brain has drawn a blank on the following.
The decoded json looks like this
[Array]
item {
[0]
{
[live]=>
[name]=>Paul
[value]=>10
}
[1]
{
[live]=>1
[name]=>Fred
[value]=>32
}
and so on
The problem I'm having is this - I'm trying to iterate through the structure to test first if live==1 and then if it's the first live name, to output it as a selected value to a HTML drop down.
I'm currently trying like this
$t = 0;
$count = 0;
foreach($decode['items'] as $option=>$value)
{
print_r("option = $option\n");
if ($option=>isLive == 1)
{
print_r("isLive is true for $option[$count]['names']\n");
if ($t == 0)
{
echo "<option value=$option[name] selected>$value[name]</option>";
$t = 1;
}
else
echo "<option value=$option[name]>$value[name]</option>";
}
else
{
print_r("isLive is false for $option[$count]=>name\n");
}
$count++;
}
the problem is that I don't seem to be able to get the if statement correct for this to work. This is probably a seriously simple problem and will no doubt make me face palm, but I could do with a pointer in the right direction here!

Answer 1

If the json is like you showed us you could not iterate over anything with your foreach because your array does not contain a key named items.
Using the provided structure this should do the trick:
foreach($decode["item"] as $item) {
if($item->live == 1) {
...
} else {
...
}
}
If $item is not an object use $item['live'] instead.
P.S.: You should really turn error_reporting on. $option=>isLive is no valid syntax.

Answer 2

$t = 0;
$count = 0;
$arr = json_decode($json,true);
foreach($arr as $key=>$val)
{
print_r($key);
if($val['live'])
{
if($t == 0)
{
echo '<option value='.$val['name'].' selected>'.$val['name'].'</option>';
$t = 1;
}
else
{
echo '<option value='.$val['name'].'>'.$val['name'].'</option>';
}
}
else
{
echo $key.' not printed cause it hasn\'t live set to true';
}
$count++;
}
