How can improper quoting in PHP code lead to syntax errors and affect script execution?

Improper quoting in PHP code can lead to syntax errors and affect script execution because PHP requires specific syntax for string literals. If quotes are not properly used, PHP may interpret them as part of the code instead of as string delimiters. To solve this issue, always ensure that quotes are correctly matched and used according to PHP syntax rules. 

// Incorrect quoting causing syntax error
$name = 'John"; // Incorrectly terminated string with mismatched quotes

// Corrected quoting
$name = 'John'; // Properly quoted string
