How can developers ensure that the correct values are displayed when mapping abbreviations to full text using arrays in PHP?

When mapping abbreviations to full text using arrays in PHP, developers can ensure that the correct values are displayed by creating an associative array where the keys are the abbreviations and the values are the corresponding full text. By using the abbreviation as the key to access the full text value, developers can easily retrieve and display the correct values.

// Define an associative array mapping abbreviations to full text
$abbreviationMapping = [
    'PHP' => 'Hypertext Preprocessor',
    'HTML' => 'Hypertext Markup Language',
    'CSS' => 'Cascading Style Sheets'
];

// Example of displaying the full text for a given abbreviation
$abbreviation = 'PHP';
echo $abbreviationMapping[$abbreviation]; // Output: Hypertext Preprocessor
