How to loop through an array of objects that have been decoded from JSON in PHP, and echo the values

Question

I'm new to PHP and am not sure how to proceed. The array that I get back from decoding the JSOn is: (sorry if its formatted weird)

array(3) {
 [0]=> array(4) { 
   ["Name"]=> string(22) "Brent's Medical Center"
   ["date"]=> string(26) "/Date(1330449077600-0700)/"
   ["dealType"]=> string(13) "Capital Lease" 
   ["id"]=> string(11) "MO-N007175A" 
 } 
 [1]=> array(4) { 
   ["Name"]=> string(22) "Brent's Medical Center" 
   ["date"]=> string(26) "/Date(1330448929213-0700)/" 
   ["dealType"]=> string(2) "NA"  ..... ["id"]=> string(11) "MO-N007172Q" } [2]=> array(4) { ["Name"]=> string(15) "MOC" ["date"]=> string(28) "/Date(-62135571600000-0700)/" ["dealType"]=> string(2) "NA" ["id"]=> string(9) "MC" } }

I have used this foreach loop, but am not sure how to get each individual item out of an associative array.

foreach ($obj as $key => $value) {
    print_r($key);
}

This returns:

I have tried other solutions, but to no avail. Maybe I'm not understanding completely what's happening, but I can't get anything to do what I need/want. Thanks!

To clarify what I'm doing - I need to print out the data in a table format. So each array will essentially be it's own row, and each individual piece will be its own cell. That's what I'm trying to accomplish. — mdance

Well, it depends exactly how you want it returned.

foreach ($obj as $key => $value) {
   print_r($value);
}

Would return your data like this:

array(4) { 
 ["Name"]=> string(22) "Brent's Medical Center"
 ["date"]=> string(26) "/Date(1330449077600-0700)/"
 ["dealType"]=> string(13) "Capital Lease" 
 ["id"]=> string(11) "MO-N007175A" 
} 
array(4) { 
 ["Name"]=> string(22) "Brent's Medical Center" 
 ["date"]=> string(26) "/Date(1330448929213-0700)/" 
 ["dealType"]=> string(2) "NA"  
 ["id"]=> string(11) "MO-N007172Q" 
} 

... etc

If you wanted individual data pieces via your example, it would be like this:

foreach ($obj as $each_array) {
   foreach ($each_array as $val){
      echo $val . "<br>";
   }
}

Which would return:

Brent's MedicalCenter
/Date(1330449077600-0700)/
Capital Lease
... etc

This is really close - To clarify what I'm doing - I need to print out the data in a table format. So each array will essentially be it's own row, and each individual piece will be its own cell. That's what I'm trying to accomplish.

You have nested objects, try the following:

echo '<table>';

foreach ($obj as $key => $value) {
    echo '<tr>';
    echo '<td>' . $value->Name . '</td>';
    echo '<td>' . $value->date . '</td>';
    echo '<td>' . $value->dealType . '</td>';
    echo '<td>' . $value->id . '</td>';
    echo '</tr>';
}

echo '</table>';

when I echo the $value["Name"] or whatever else, it echo's nothing and the rest of my script stops.

Can you add <?php ini_set('display_errors', 1); ?> to the top of your script and see if that reports a descriptive error?

mdance Over a year ago

It doesn't output anything. =(

Martin Over a year ago

Can you put the result of <?php print_r($obj); ?> in your question?

Assuming that $data is what was var_dump'd in your pasted content:

foreach($data as $record) {
    //$record['name'] is now something like "Brent's medical center"
}

Note though that you'll have to process the date field into something more usable than a string.

Script echo's exactly what you ask it to echo - array keys(indexes). Array has 3 values, so its keys are 0, 1, 2.

Looks like you need $value variable insode foreach-loop.

I hope it helps.

Here's a simplified version of your problem. Substitute your array for the one here.

<?php
$arr[0] = array('uno'=>'one', 'dos'=>'two');
$arr[1] = array('AAAA'=>'aaaa', 'BBBB'=>'bbbb');

foreach ($arr as $obj) {
    foreach ($obj as $k=>$v) {
        echo "key:$k=>val:$v\n";
    }
}
?>

If you want to access something specific, you can do it like this:

echo $arr[1]["BBBB"]; // echoes bbbb

Or...

echo $arr[1]["Name"]; // echoes Brent's Medical Center

Your variable is an array filled with associative arrays. So when you're doing your loop and operating on $key, that's not the data, but the index of your parent array. So simply changing the part of the array you're dealing with will fulfill your original code sample.

foreach ($obj as $key => $value) {
    print_r($value);
}

Now each $value is the associative array with the keys Name, date, dealType, etc. So you can get your values directly, e.g. $value['Name'] for the first loop would be "Brent's Medical Center"

Thats closer - now how can I get the information out of the value array? Sorry.. I'm a total newb.

Morgon Over a year ago

Exactly as I mentioned after the code sample: $value['Name'] (modified further to attempt to be more clear). Is there something else you're trying to do besides that?

mdance Over a year ago

When I try and echo the $value['Name'] it returns the entire $obj array, and the rest of my script stops.

mdance Over a year ago

Actually thats not whats happening - sorry. I still cant access individual pieces with echo $value['Name'];

To clarify what I'm doing - I need to print out the data in a table format. So each array will essentially be it's own row, and each individual piece will be its own cell. That's what I'm trying to accomplish.
