What are some common challenges faced by beginners when trying to manipulate arrays in PHP?

One common challenge faced by beginners when manipulating arrays in PHP is accessing and modifying specific elements within a multidimensional array. To solve this issue, beginners can use nested loops to iterate through the array and access the desired elements. Additionally, using built-in array functions such as array_push() or array_pop() can help in adding or removing elements from an array. 

// Example of accessing and modifying elements in a multidimensional array
$students = array(
    array("name" => "John", "age" => 20),
    array("name" => "Jane", "age" => 22)
);

// Accessing and modifying elements in the array
foreach($students as $key => $student){
    $students[$key]['age']++; // Incrementing the age of each student by 1
}

print_r($students);
