Are there any specific PHP syntax rules that the user may have overlooked in their code?

One specific PHP syntax rule that users may overlook is the use of semicolons at the end of each statement. Semicolons are used to separate statements in PHP, and forgetting to include them can lead to syntax errors. It is important to ensure that each statement is properly terminated with a semicolon to avoid any issues with the code execution.

// Incorrect code without semicolons
$variable1 = 10
$variable2 = 20

// Corrected code with semicolons
$variable1 = 10;
$variable2 = 20;
