merge array with itself from foreach loop

Question

I have foreach loop like:

foreach($attributes as $key => $value)
{
     $option[] =["$value->name"=>"$value->value"]; //it is like ["color"=>"red"]
}

I want to merge $option[0], $option[1] and so on.... How to merge that ?

I tried:

for($i=1;$i<$count;$i++)
{   
        $option = array_merge($option[0],$option[$i]);
}

What about this: $option[$value->name] = $value->value; in foreach? This array will contain all key/value pairs of options. — user4035

If that does not fulfill your needs, give an example for clarification (in the question). — syck

@DeepParekh I gave you a preliminary answer. Let me know, how it worked. — user4035

user4035 is correct: if you want it then you will directly have an array where, for instance, $option['color] is 'red', Or, if you want to follow your approach, you can either declare a new array ($opt = []; foreach ($options as $value) $opt = array_merge($opt, $value);) or put the value in $option[0] instead of $option; or you can read these answers which have ways of flattening an array — frarugi87

If you want a merged version, try this (you need only 1 loop):

$merged_options = array();
foreach($attributes as $key => $value)
{
     $option[] =["$value->name" => "$value->value"];
     $merged_options[$value->name] = $value->value;
}

This code should hopefully loop through each of your current arrays and reconstruct it to a multi-dimensional array.

foreach($attr as $k=>$v):
    $temp = array();
    $i = 0;
    while(count($k) != $i):
        array_push($temp, $k[$i] => $v[$i]);
        $i++;
    endwhile;
    array_push($attr, $temp);
endforeach;

Hope it helped.

Why not you use something like this:

foreach($attributes as $key => $value)
{
     $option[$value->name] =$value->value;
}
