How can PHP developers avoid variable naming conflicts when writing to Excel using PHPExcel?

To avoid variable naming conflicts when writing to Excel using PHPExcel, developers can prefix their variable names with a unique identifier or use namespaces to encapsulate their code. This will help prevent naming collisions with built-in PHPExcel variables or other variables in the script. 

// Prefix variable names with a unique identifier
$excel_data = array(
    'Name' => 'John Doe',
    'Age' => 30,
    'Email' => 'johndoe@example.com'
);

// Use namespaces to encapsulate code
namespace MyExcel;

$excel_data = array(
    'Name' => 'Jane Smith',
    'Age' => 25,
    'Email' => 'janesmith@example.com'
);
