Hello,

I need you help folks. Struck in between.

I got two arrays.

PHP Code:

$a1 = array(-0.005584046,-0.029838394,-0.02776031);
$a2 = array(-0.001116809,-0.006861126,-0.011040963); 

I want to compare both the arrays and store the result in third array.

Any help will be appreciated.

Thanks

When you say compare... you want to add them up? You want to see if they are identical? You want to add or remove similar or dissimilar values?

If you could, please give the desired result you'd expect to get from the given arrays.

As Keith has said, without more information as to what you are wanting to do with the values, it's hard to guide you here. I suggest you take a look at the manual for a list of array functions you can use (Go down to the Table of Contents area)

The answer is "yes".

Sorry friends, just couldn't complete my question. I need to compare the first value of array1 with the first value of array2; if a1<a2, I need to store "B" to array3, else "S". The same will be from 1st element to last element of array.

Thanks

Something like this?

PHP Code:

$a1 = array(-0.005584046,-0.029838394,-0.02776031);
$a2 = array(-0.001116809,-0.006861126,-0.011040963);
$a3=array();
foreach($a1 as $k=>$v)
{
$a3[]=($v<$a2[$k])?'B':'S';
}

print_r($a3);

Now how were we unable to figure out that on our own?
