PHP Check that variable is an array

Here is an example of how to check a variable is array or not –

$array = array('a', 'b', 'c');

if(is_array($array)){
echo "This is array.";
}else{
echo "This is not array.";
}
//will print - This is array

The above example will print – This is array because we passed array variable to check.

Now lets go with another example which is not array

$str = "abcd";

if(is_array($str)){
echo "This is array.";
}else{
echo "This is not array.";
}
//will print - This is not array

The above example will print – This is not array because we passed string variable to check and this function will refurn false so it will go in else condition.
