How can PHP developers improve code readability and maintainability by following standard conventions for string and variable declarations?

PHP developers can improve code readability and maintainability by following standard conventions for string and variable declarations. This includes using meaningful variable names, following a consistent naming convention (such as camelCase or snake_case), and properly formatting strings with single or double quotes. By adhering to these conventions, developers can make their code more understandable for themselves and others who may need to work on or maintain it in the future. 

// Bad example
$var = "Hello, world!";
$myString = 'This is a string.';

// Good example
$greeting = 'Hello, world!';
$myString = "This is a string.";
