Explain conditional statements in PHP.
Updated May 24, 2026
Short answer
Conditional statements execute code based on specific conditions using if, else, elseif, and switch.
Deep explanation
Conditionals control program flow. PHP evaluates boolean expressions and executes matching blocks. switch is useful for multiple known values, while if statements are flexible for complex conditions.
Real-world example
Access control systems check user roles before displaying admin dashboards.
Common mistakes
- Using assignment instead of comparison operators inside conditions.
Follow-up questions
