How can a foreach loop be used effectively to iterate through a multidimensional array in PHP?
To iterate through a multidimensional array in PHP using a foreach loop, you can nest multiple foreach loops within each other to traverse through each level of the array. By using nested foreach loops, you can access and manipulate the values of the inner arrays within the multidimensional array.
$multiArray = array(
array(1, 2, 3),
array(4, 5, 6),
array(7, 8, 9)
);
foreach ($multiArray as $innerArray) {
foreach ($innerArray as $value) {
echo $value . " ";
}
echo "\n";
}
