What potential issues can arise when assigning values from multiple variables to a single variable in PHP?

One potential issue that can arise when assigning values from multiple variables to a single variable in PHP is that the values may not be concatenated correctly, resulting in unexpected output. To solve this issue, you can use the concatenation operator (.) to combine the values of the variables into a single string. 

// Assign values from multiple variables to a single variable using concatenation operator
$var1 = "Hello";
$var2 = "World";
$combined = $var1 . " " . $var2;

echo $combined; // Output: Hello World
