php - How to determine if an array has any elements or not?

Question

How do I find if an array has one or more elements?

I need to execute a block of code where the size of the array is greater than zero.

if ($result > 0) {
    // Here is the code body which I want to execute
} 
else {
    // Here is some other code
}

You can use the count() or sizeof() PHP functions:

if (sizeof($result) > 0) {
    echo "array size is greater than zero";
}
else {
    echo "array size is zero";
}

Or you can use:

if (count($result) > 0) {
    echo "array size is greater than zero";
}
else {
    echo "array size is zero";
}
