How can PHP developers troubleshoot issues related to variable accessibility between PHP blocks in a script?

Variable accessibility issues between PHP blocks in a script can be troubleshooted by ensuring that variables are properly declared and initialized within the appropriate scope. Developers should check for any typos or misspelled variable names that may be causing the issue. Additionally, using functions or classes to encapsulate variables can help prevent conflicts between different PHP blocks. 

<?php
// Declare and initialize a variable within the appropriate scope
$variable = "Hello, World!";

// Use a function to encapsulate the variable
function displayVariable() {
    global $variable;
    echo $variable;
}

// Call the function to display the variable
displayVariable();
?>
