How can nested double quotes within a string in PHP cause parsing errors and how can they be fixed?

Nested double quotes within a string in PHP can cause parsing errors because PHP interprets the inner double quotes as the end of the string. To fix this issue, you can escape the inner double quotes using a backslash (\) before each double quote. 

$string = "This is a string with nested \"double quotes\" that are properly escaped.";
echo $string;
