What is the potential issue with the code snippet provided in the forum thread regarding multidimensional arrays in PHP?

The potential issue with the code snippet provided is that it is trying to access elements in a multidimensional array using incorrect syntax. To access elements in a multidimensional array, you need to specify the index for each dimension. To solve this issue, you should access elements in the multidimensional array by specifying the indexes for each dimension separated by commas within square brackets. 

// Incorrect code snippet
$multiArray = array(
    array(1, 2),
    array(3, 4)
);

// Accessing elements using incorrect syntax
echo $multiArray[0][0]; // This will not work

// Correct way to access elements in a multidimensional array
echo $multiArray[0][0]; // Outputs 1
