I have an assignment to do but am having trouble understanding the given psuedocode :/

<?php
$bucket = new array();
print $bucket->addrocks('Rock1')->addrocks('rock2')-
>addrocks('Rock3');

echo "<h1>My Bucket</h1>";
echo "<ul>";
foreach($bucket as $rock){
echo "<li>". $rock ."</li>";
}
echo "</ul>";
?>

Now my trouble starts with understanding how they want me to construct the array after the “print” call? i am not looking for a direct answer to this just maybe a tutorial link or a finger in the right direction

Thank you in advance

What is the easiest way to check if an has array keys that don’t match a particular list?

$a = array(
  [ignore_me] => "blah blah blah",
  [name] => "Don"
);

does_array_have_non_ignored_entries($a); // returns true

I can think of a ton of ways to write this function, didn’t know if PHP has a quick solution. Best one I have is this:

$length = count($a);
$ignored_entry = (in_array($a, 'ignore_me') ? 1 : 0;
if ($length - $ignored_entry > 0) {...}

I have an array called “VALUES” that contains multiple arrays. In these array there is a field named “test”, I only want the arrays pointed out that contains the number 4 in the test field.

my current output for Values array:

Array ( 

[0] => Array ( [entry_id] => 41149 [o_number] => 000001 [test1] => 000001 [test2] => 1234 [lev] => Ja [fak] => Mail [beta] => 30 [test] => 4 ) 

[1] => Array ( [entry_id] => 41142 [o_number] => 000202[test1] => 000202 [test2] => 1234 [lev] => Ja [fak] => Mail [beta] => 30 [test] => 4 ) 

[2] => Array ( [entry_id] => 41103 [o_number] => 000003 [test1] => 000003 [test2] => 1234 [lev] => Ja [fak] => Mail [beta] => 30 [test] => 4 ) 

[3] => Array ( [entry_id] => 41101 [o_number] => 000044 [test1] => 000044 [test2] => 1234 [lev] => Ja [fak] => Manuel/brev [beta] => 10 [test] => 2 ) 

[4] => Array ( [entry_id] => 41100 [o_number] => 000542 [test1] => 000542 [test2] => 1234 [lev] => Ja [fak] => Mail [beta] => 30 [test] => 4 ) 

[5] => Array ( [entry_id] => 41088 [o_number] => 001231 [test1] => 001231 [test2] => 1234 [lev] => Ja [fak] => Mail [beta] => 30 [test] => 3 ))

desired output:

Array ( 

[0] => Array ( [entry_id] => 41149 [o_number] => 000001 [test1] => 000001 [test2] => 1234 [lev] => Ja [fak] => Mail [beta] => 30 [test] => 4 ) 

[1] => Array ( [entry_id] => 41142 [o_number] => 000202[test1] => 000202 [test2] => 1234 [lev] => Ja [fak] => Mail [beta] => 30 [test] => 4 ) 

[2] => Array ( [entry_id] => 41103 [o_number] => 000003 [test1] => 000003 [test2] => 1234 [lev] => Ja [fak] => Mail [beta] => 30 [test] => 4 ) 

[3] => Array ( [entry_id] => 41100 [o_number] => 000542 [test1] => 000542 [test2] => 1234 [lev] => Ja [fak] => Mail [beta] => 30 [test] => 4 ))

I tried with a foreach but it didn’t work

    foreach ($values as $key) 
    {
        if($key === 4)
        {
//This will only show
    print_r($key);

//delete array?

        }
    }

I have two arrays:

$array1 = array('a' => 1, 'b' => 2, 'c' => 3);
$array2 = array('d' => 4, 'e' => 5, 'f' => 6, 'a' => 'new value', '123' => 456);

I want to merge them and keep the keys and the order and not re-index!!

How to get like this?

Array
(
    [a] => new value
    [b] => 2
    [c] => 3
    [d] => 4
    [e] => 5
    [f] => 6
    [123] => 456
)

I try to array_merge() but it will not be preserved the keys:

print_r(array_merge($array1, $array2));

Array
(
    [a] => 'new value'
    [b] => 2
    [c] => 3
    [d] => 4
    [e] => 5
    [f] => 6
    [0] => 456
)

I try to the union operator but it will not overwriting that element:

print_r($array1 + $array2);

Array
(
    [a] => 1   <-- not overwriting
    [b] => 2
    [c] => 3
    [d] => 4
    [e] => 5
    [f] => 6
    [123] => 456
)

I try to swapped place but the order is wrong, not my need:

print_r($array2 + $array1);

Array
(
    [d] => 4
    [e] => 5
    [f] => 6
    [a] => new value 
    [123] => 456
    [b] => 2
    [c] => 3
)

I dont want to use a loop, is there a way for high performance?

I’m having trouble returning a value out of a nested array…

the array dump looks like this

object(myObj)#1 (3) { 
["thing1"]=> string(5) "abcde" 
["thing2"]=> string(2) "ab"
["data"]=> array(3) { 
    [0]=> string(3) "370" 
    ["id"]=> string(3) "370" 
    [1]=> string(26) "" 
    ["name"]=> string(26) "abcdefghijklmnopqrstuvwxyz" 
    [2]=> string(0) "" 
    ["address"]=> string(0) "" 
    [3]=> string(4) "wxyz" 
    ["email"]=> string(4) "wxyz"
}

I want to get to “name” inside the “data” array….

I’ve tried

echo $myObj['data']['name'];

also

echo $myObj -> $data -> $name;

they always come back as UNDEFINED.
