What are some strategies for giving variables meaningful names in PHP to improve code readability and understanding, especially when working with complex data structures like multidimensional arrays?

When working with complex data structures like multidimensional arrays in PHP, it is important to give variables meaningful names to improve code readability and understanding. One strategy is to use descriptive names that indicate the purpose or content of the variable. Another approach is to follow a consistent naming convention, such as camelCase or snake_case, to make the code more organized. Additionally, consider using comments to explain the purpose of the variables in cases where the names alone may not be sufficient. 

// Example of giving variables meaningful names for better readability in PHP

// Using descriptive names to indicate the purpose or content of the variable
$userData = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
];

// Following a consistent naming convention like camelCase
$employeeDetails = [
    'employeeName' => 'Alice Smith',
    'employeeAge' => 25,
    'employeeEmail' => 'alicesmith@example.com'
];

// Adding comments to explain the purpose of the variables
// $studentData contains information about a student
$studentData = [
    'studentName' => 'Bob Johnson',
    'studentAge' => 22,
    'studentEmail' => 'bobjohnson@example.com'
];
