I am having trouble accessing the values in an array, the array looks like this,

I am trying to get the values out, I have tried doing the following,

foreach ($result as $rslt) {
    echo $rslt->id;
}

I have also tried,

foreach ($result as $rslt) {
    $rslt['id'];
}

But none of this works, I dont know why, can anyone help?


To point out a few things and hopefully clarify any confusion, in your first example:

foreach ($result as $rslt) {
    echo $rslt->id;
}

The arrow operator (->) is misused. It's commonly used to invoke a method on a class object, in your case $rslt would be a class object and id would be a method, which isn't the case.

In your second example,

foreach ($result as $rslt) {
    $rslt['id'];
}

You almost hit the nail on the head, but you had forgot to call echo or print to output the value onto the screen.

Also, your $result array has a sub-array at index 0, so that would need to change

$rslt['id'];

to, along with the echo or print statement.

echo $rslt[0]['id'];


The second is correct, but you're missing an echo or print

echo $rslt['id'];

From the example code you give it's not clear what $result is.
If $result encompasses all the listed arrays, you will have to do

foreach($result as $rslt) {
    echo $rslt[0]['id'];
}

Further reference:

I'm sure someone will post the answer in the next 0.3 seconds so I'll just try to help you with your methodology instead. Clearly you know how to use print_r (or var_dump). Have you tried using it on $rslt within your array? You seem to have difficulty understanding what $rslt is.


foreach($result as $rslt) {
    echo $rslt[0]['id'];
}
