Getting multiple keys for value in array

[Staggan]

Hello

 

I am having some trouble with array_keys

 

I have an array for which I want to return all the keys based on value X

 

This is my code:

 

$depth = array_keys(X', $Array);

echo print_r ($depth,1);

 

I have checked the content of my array $Array and it contains at least 1 instance of 'X' but I am getting nothing when I do the print_r

 

Any suggestions would be appreciated

 

Thanks

Your params in array_keys are the wrong way around. Take a look at the following:

 

<?php
$foo = array('a','b','c','d','a');
$keys = array_keys($foo, 'a');
print_r($keys);
?>

Doh!

 

I thought I checked that!

 

I have another question if you could help...

 

I have these two arrays:

 

Array1

Array
(
    [Arctictrek's Indiana] => Array
        (
            [0] => 6
        )

    [storm Kloud's Chosen to Win] => Array
        (
            [0] => 5
        )

    [storm Kloud's Keep the Win] => Array
        (
            [0] => 11
        )

    [storm Kloud's Hharmony] => Array
        (
            [0] => 12
        )

    [Fire 'N Ice In Conclusion] => Array
        (
            [0] => 29
        )

    [Jacbar Alaskan Black Night] => Array
        (
            [0] => 13
        )

    [Rameslyn Cherokee Squaw] => Array
        (
            [0] => 14
        )

    [Highnoons Kaskinampo of Jacbar] => Array
        (
            [0] => 27
        )

    [Malnorska's Gypsy Lady] => Array
        (
            [0] => 28
        )

    [Highnoons Loucheuse] => Array
        (
            [0] => 30
        )

)


Array 2

Array
(
    [Arctictrek's Indiana] => Array
        (
            [0] => 6
        )

    [storm Kloud's Chosen to Win] => Array
        (
            [0] => 11
        )

    [storm Kloud's Keep the Win] => Array
        (
            [0] => 23
        )

    [storm Kloud's Hharmony] => Array
        (
            [0] => 24
        )

    [Fire 'N Ice In Conclusion] => Array
        (
            [0] => 25
            [1] => 29
        )

    [Jacbar Alaskan Black Night] => Array
        (
            [0] => 13
        )

    [Rameslyn Cherokee Squaw] => Array
        (
            [0] => 14
        )

    [Highnoons Kaskinampo of Jacbar] => Array
        (
            [0] => 27
        )

    [Malnorska's Gypsy Lady] => Array
        (
            [0] => 28
        )

    [Highnoons Loucheuse] => Array
        (
            [0] => 30
        )

)

 

For each named element in Array 1 I want to add the value from Array 2, so for example, adding Highnoons Loucheuse in Array 1 to Highnoons Loucheuse in Array 2 would give me 30+30, equalling 60....

 

But, Fire 'N Ice In Conclusion has one entry in Array 1 and two in Array 2, and when this happens I want to add the value in Array 1 to the first value in Array 2, giving me one answer, and then add the value in Array 1 to the second value in Array 2, giving me an additional answer.....

 

I need to do this both ways round, where Array 1 could also have multiple entries for the same array....

 

Any suggestions?

 

Thanks

This is the code for 1 way where array 1 has 1 value and array 2 has more than 1. See if you can amment to do both ways.

 

<?php
$a1 = array('Arctictrek\'s Indiana' => array(6),
		'Storm Kloud\'s Chosen to Win' => array(5),
		'Storm Kloud\'s Keep the Win' => array(11),
		'Storm Kloud\'s Hharmony' => array(12),
		'Fire \'N Ice In Conclusion' => array(29),
		'Jacbar Alaskan Black Night' => array(13),
		'Rameslyn Cherokee Squaw' => array(14),
		'Highnoons Kaskinampo of Jacbar' => array(27),
		'Malnorska\'s Gypsy Lady' => array(28),
		'Highnoons Loucheuse' => array(30));

$a2 = array('Arctictrek\'s Indiana' => array(6),
		'Storm Kloud\'s Chosen to Win' => array(11),
		'Storm Kloud\'s Keep the Win' => array(23),
		'Storm Kloud\'s Hharmony' => array(24),
		'Fire \'N Ice In Conclusion' => array(25,29),
		'Jacbar Alaskan Black Night' => array(13),
		'Rameslyn Cherokee Squaw' => array(14),
		'Highnoons Kaskinampo of Jacbar' => array(27),
		'Malnorska\'s Gypsy Lady' => array(28),
		'Highnoons Loucheuse' => array(30));

// make sure both arrays have the same num elements
if(count($a1) == count($a2)) {
for($x = 0; $x < count($a1); $x++) {
	$key = key($a1);
	print $key."<br />";
	$start_val = $a1[$key][0];
	print "Start Value: ".$start_val."<br />";
	for($i = 0; $i < count($a2[$key]); $i++) {
		print "Sum: ".$start_val."+".$a2[$key][$i]."<br />";
		$equals = $start_val+$a2[$key][$i];
		print "Equals: ".$equals."<br />";
	}
	print "<br />";
	next($a1);
}
}
?>

 

Will produce

 

Arctictrek's Indiana
Start Value: 6
Sum: 6+6
Equals: 12

Storm Kloud's Chosen to Win
Start Value: 5
Sum: 5+11
Equals: 16

Storm Kloud's Keep the Win
Start Value: 11
Sum: 11+23
Equals: 34

Storm Kloud's Hharmony
Start Value: 12
Sum: 12+24
Equals: 36

Fire 'N Ice In Conclusion
Start Value: 29
Sum: 29+25
Equals: 54
Sum: 29+29
Equals: 58

Jacbar Alaskan Black Night
Start Value: 13
Sum: 13+13
Equals: 26

Rameslyn Cherokee Squaw
Start Value: 14
Sum: 14+14
Equals: 28

Highnoons Kaskinampo of Jacbar
Start Value: 27
Sum: 27+27
Equals: 54

Malnorska's Gypsy Lady
Start Value: 28
Sum: 28+28
Equals: 56

Highnoons Loucheuse
Start Value: 30
Sum: 30+30

Thanks...

 

Trying to modify now

 

 

[Staggan]

OK, I got this working... but am still having an issue....

 

Before the code you posted I do some work on some of the array values, which are then stored back in the array in the same place.. works fine and when I do a print_r of the array it looks identical in format to the original....

 

However, there is a line in the code you posted:

 

 $key = key($a1);

 

 

And this no longer works....

 

If I remove my code before yours, it works fine, if not, it does not return a value..

 

Any ideas why?

 

Here is my code and yours together (plus my change to make it work with multiple values either side)

 

 

// CHANGE ID TO DEPTH DAM


for ($i = 0 ; $i < count ($damdepth) ; $i++){

	$key = key($damdepth);

	$count = count ($damdepth[$key]);

	for ($y = 0 ; $y < $count ; $y++){

	$position =  ($damdepth[$key][$y]);

	$realdepth = getDepth($position);
	$damdepth[$key][$y] = $realdepth;
	}

	//echo $count;
	next($damdepth);
}

// CHANGE ID TO DEPTH SIRE


for ($i = 0 ; $i < count ($siredepth) ; $i++){

	$key = key($siredepth);

	$count = count ($siredepth[$key]);

	for ($y = 0 ; $y < $count ; $y++){

	$position =  ($siredepth[$key][$y]);

	$realdepth = getDepth($position);
	$siredepth[$key][$y] = $realdepth;
	}

	//echo $count;
	next($siredepth);
}





if(count($siredepth) == count($damdepth)) {	


for($x = 0; $x < count($siredepth); $x++) {		

 $key = key($siredepth);		

echo $key;	

for($y = 0; $y < count($siredepth[$key]); $y++) {		


 print $key."<br />";		
 $start_val = $siredepth[$key][$y];		

 print "Start Value: ".$start_val."<br />";		

 for($i = 0; $i < count($damdepth[$key]); $i++) {			

 print "Sum: ".$start_val."+".$damdepth[$key][$i]."<br />";			
 $equals = $start_val+$damdepth[$key][$i];			

 print "Equals: ".$equals."<br />";		

 }		

 print "<br />";		

next ($siredepth[$key]);
}
 next($siredepth);	
 }

 }	

 

Thanks

Solved it!

 

Had to reset the array pointer!
