How to resolve the issue of if-else statements not executing in PHP?

If the if-else statement in PHP is not executed, it may be due to a few reasons.

1. The conditional expression is incorrect: Please ensure that the condition in the if statement is correct to ensure that the if statement block will be executed when the condition is met.
2. Variables are not properly initialized: Check if the variables used in the condition statement are properly initialized. If the variables are not properly initialized, it could result in unexpected condition outcomes.
3. Code logic error: Verify the correct nesting and usage of if-else statements in the code to ensure the logical structure is correct.
4. Syntax error in PHP: Check for syntax errors in the code, such as unclosed parentheses or other syntax issues, which may prevent the if-else statement from being executed.

If everything above is fine, you can try using the var_dump() function or an echo statement to output intermediate results, in order to determine which step the program has reached and identify the issue.
