Hello

Given I have an array as such: (as an example)

Array ([0]=>+1.,[1]=>+2.,[2]=>-3.0,[3]=>A3B)

I want to return an array as such: Array ([0]=>1,[1]=>2,[2]=>3,[3]=>A3B)

basically if its a number remove leading + or - char from number and any decimal point but do not do anything with letters or anything with number and char combination such as 2B or A3 and so forth.

I can strip the numbers with this function:

$number = preg_replace("/[[:^digit:]]/", '', $number);

So basically I have to traverse an array element by element check if it is a number and if so strip it otherwise leave it alone and go to next and save the results into an array and the return that array. Or I can simply remove plus, minus or dot chars from every element. (that is all that I would need as that would cover every conceivable scenario)

Can someone suggest how to code this?

Thanks
