How can PHP developers ensure that their code for incrementing variables is efficient and easily understandable for others?

To ensure that PHP code for incrementing variables is efficient and easily understandable, developers can use the increment operator (++). This operator increments the value of a variable by 1 in a concise and clear manner. By using this operator, developers can avoid writing verbose code and make the intention of incrementing the variable explicit to others who may read the code.

// Using the increment operator to efficiently and clearly increment a variable
$counter = 0;
$counter++;
echo $counter; // Output: 1
