PHP How to test a value of standard class object - php

Question

I would like to check if the value of a standard class object has a value of 'None'. The object is a PDO and pulls data from the database.
Here is the data from a var_dump:
array (size=1)
0 =>
object(stdClass)[8]
public 'Subid' => string '1' (length=1)
public 'id' => string '27' (length=2)
public 'english' => string 'English Standard' (length=16)
public 'maths' => string 'Mathematics General 2' (length=21)
public 'hsie1' => string 'Modern History' (length=14)
public 'science1' => string 'Biology' (length=7)
public 'science2' => string 'None' (length=4)
public 'science3' => string 'None' (length=4)
public 'tech1' => string 'Agriculture' (length=11)
public 'tech2' => string 'None' (length=4)
public 'extension' => string 'None' (length=4)
public 'arts1' => string 'None' (length=4)
public 'arts2' => string 'Dance' (length=5)
public 'pdhpe1' => string 'None' (length=4)
public 'vet1' => string 'None' (length=4)
public 'start_time' => string '2016-11-15 19:54:08' (length=19)
Is it possible to loop through the keys and test the values?

Answer 1

You can foreach over an array and the public properties of an object
So
foreach ( $array as $obj ) {
foreach ( $obj as $prop => $val ) {
if ( $val == 'None' ) {
echo $prop . ' = ' . $val;
}
}
}
EDIT:
I dont see why you had to change anything here is a quick test I ran
$o = new stdClass;
$o->p1 = 1;
$o->p2 = 'two';
$o->p3 = 'None';
$array = array($o);
var_dump($array);
foreach ( $array as $obj ) {
foreach ( $obj as $prop => $val ) {
if ( $val == 'None' ) {
echo $prop . ' = ' . $val;
}
}
}
And the results were
array(1) {
[0] =>
class stdClass#1 (3) {
public $p1 => int(1)
public $p2 => string(3) "two"
public $p3 => string(4) "None"
}
}
p3 = None
