如何匹配单独数组中的数组键

Question

I have two separate arrays - $array_before and $array_after. Each array can have an unlimited number of values. I can output individual values of the array like so:

print $array_before->field_things[0]['value'] 

or

print $array_after->field_other_things[0]['value'] 

or I can print all of the values in each array separately:

foreach($array_before->field_things as $before_stuff)
{
print $before_stuff['value']
}

But that give me this:

Before Value 0
Before Value 1
Before Value 2
Before Value 3...
--------
After Value 0
After Value 1
After Value 2
After Value 3...

What I need to do is out put BOTH array values grouped by thier array keys like this:

Before Value 0
After Value 0
-------
Before Value 1
After Value 1
------
Before Value 2
After Value 2

Answer 1

Do $array_before->field_things and $array_after->field_other_things have the same length after the transformation? Then you can just iterate through the indices into them:

for ( $i=0; $i<count($array_before->field_things); $i++ ) {
    print "Before value: ".$array_before->field_things[i]['value']
    print "After value: ".$array_after->field_other_things[i]['value']
}
