In what scenarios might the use of var_dump() be beneficial for identifying and resolving PHP variable passing issues?

When encountering PHP variable passing issues, using var_dump() can be beneficial for identifying the data type and value of variables at different points in the code. This can help pinpoint where the issue lies, such as incorrect variable assignments or unexpected data transformations. By using var_dump(), developers can quickly identify and resolve these variable passing issues. 

// Example code snippet demonstrating the use of var_dump() to identify and resolve variable passing issues

$variable1 = "Hello";
$variable2 = "World";

// Before passing variables
var_dump($variable1, $variable2);

function concatenateStrings($var1, $var2) {
    $result = $var1 . " " . $var2;
    return $result;
}

$newString = concatenateStrings($variable1, $variable2);

// After passing variables
var_dump($newString);
