How can syntax errors, like unexpected tokens, be avoided in PHP code?

Syntax errors, such as unexpected tokens, can be avoided in PHP code by ensuring proper syntax is used throughout the code. This includes correctly closing parentheses, brackets, and quotes, as well as ensuring proper placement of semicolons at the end of statements. Additionally, using an integrated development environment (IDE) or code editor with syntax highlighting can help catch syntax errors before running the code.

// Example of avoiding syntax errors by correctly closing parentheses and using semicolons

$number1 = 10;
$number2 = 20;

// Corrected syntax
$sum = $number1 + $number2;

echo "The sum is: " . $sum;
