如何在php中检查数组是否包含正值

Question

i have searched through the Internet with no luck. I have array of integers and i want to check if my array contain positive value.

my array

$Myarray = {1,3,7,-6,-9,-23,-8};

i tried to use in_array() function with no luck;

any help please?

Answer 1

A simple foreach ?

foreach($Myarray as $v)
{
    if($v>0)
    {
        echo "Array contains a +ve value";
        break;
    }
}

Another way would be this..

$Myarray = array(-1,-3,-7,-6,-9,-23,-8);
rsort($Myarray);
echo ($Myarray[0] > 0) ? "Array contains +ve value" : "Array does not contain +ve value";
