PHP Combining two arrays with same index key

Here we have two arrays $array1 and $array2.

$array1

Array ( [0] => a [1] => b [2] => a [3] => b [4] => a [5] => b ) 

Code (markup):

$array2

Array ( [0] => fruit1 [1] => flower1 [2] => fruit2 [3] => flower2 [4] => fruit3 [5] => flower3 ) 

Code (markup):

Now, i want an array with

Array (
[0] => Array ( [a] => fruit1 [b] => flower1),
[1] => Array( [a] => fruit2 [b]=> flower2),
[2] => Array( [a] => fruit3 [b] => flower3 ) 
)

Code (markup):

Can someone please guide me on how to use the array_combine in this situation ?

Thanks.

 

I dont think array_combine can be used for this scenario, or may be because I never came into such thing.

For your scenario, I have a custom function for you.

$array1 = Array("a","b","a","b","a","b");
$array2 = Array("fruit1","flower1","fruit2","flower2","fruit3","flower3");


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

function mycombine($array1,$array2) {
	$ret = Array();
	$x=0;
	foreach($array1 as $key => $index) {
		if(!isset($ret[$x])) {
			$ret[$x] = Array();
		}
		if(count($ret[$x]) ==2)
			$x++;
		$ret[$x][$index] = $array2[$key];
	}

	return $ret;
}

I hope it helps.

 

This should work too

$array1 = array ( 'a','b','a','b','a','b' );
$array2 = array ( 'fruit1', 'flower1', 'fruit2', 'flower2', 'fruit3', 'flower3' );
$array3 = array();
for($i=0; $i<count($array1); $i+=2) {
	$array3[] = array($array1[$i] => $array2[$i], $array1[$i+1] => $array2[$i+1]);
}
print_r($array3);

Thanks Vooler and vbot for the simple function. Works like a charm +ve Repped you both.

I had initially thought of getting the array into

Array (
[0] => Array ( [a] => fruit1 [b] => flower1),
[1] => Array( [a] => fruit2 [b]=> flower2),
[2] => Array( [a] => fruit3 [b] => flower3 ) 
)

Code (markup):

as mentioned above as it was directly not possible in this situation to have

Array (
 [a] => fruit1 [b] => flower1 
 [a] => fruit2 [b]=> flower2 
 [a] => fruit3 [b] => flower3
)

Code (markup):

and i would end up having

Array (
 [a] => fruit3 [b] => flower3
)

Code (markup):

as arrays need unique indexes / keys.

But later in the day after some careful thought, I have come up with this solution. Posting it here so it may be of some use to others who may encounter a similar situation.

<?php

$array1 = Array("a","b","a","b","a","b");
$array2 = Array("fruit1","flower1","fruit2","flower2","fruit3","flower3");


$fruits_array = array(); 	reset($fruits_array);
$flowers_array = array();	reset($flowers_array);

while (($val1 = each($array1)) && ($val2 = each($array2))) {

	if (preg_match("/a/i", $val1['value'])){
		$fruit_value = $val2['value'];
		array_push($fruits_array,$fruit_value);	
	}elseif (preg_match("/b/i", $val1['value'])){
		$flower_value = $val2['value'];		
		array_push($flowers_array,$flower_value);
	}														

} 

$array3 = array_combine($fruits_array,$flowers_array);

print_r($array3);

?>
