How to check if two arrays are empty

[etrader]

I have two array, how I can have if else to check if both array1 and array2 are empty?

 

if (empty both arrays) { }

else { even if one of them are not empty }

[AtomicRax]

if ($array1 == '' && $array2 == '') {
//both are empty
} else {
//one has a value
}

 

is a simple value check, but something like

 

if (count($array1) == '0' && count($array2) == '0') {
//both are empty
} else {
//one has a value
}

 

might help too? depends

[ignace]

if(empty($a1) && empty($a2)) {

 

$array1 == '' doesn't work with array's and count($array1) == '0' should be count($array1) == 0 since count() returns an integer, which wins, and the string constant '0' is converted to 0 therefor it's better to write:

 

count($a1) == 0

 

You'll avoid needless conversions.
