The way the Switch statement works is it takes a single variable as inputĪnd then checks it against all the different cases you set up for that ![]() With the use of the switch statement you can check for all theseĬonditions at once, and the great thing is that it is actually more efficient Let's see if we can do something different. This doesn't sound like much fun to code, In this example you might haveĢ0 different locations that you would have to check with a nasty long block To pack according to this destination variable.

The switch statement doesn't support logical operators like "and" and "or".It cannot operate under complex conditions. PHP's switch statement only checks for expression-case value equality.Easy to update: New conditions can be added as cases in the switch statement, making code updates simple.ĭisadvantages of the switch statement in PHP.Instead of checking each condition, it evaluates the expression once and jumps to the matching case. Switch statements are more efficient than if/else statements.It simplifies code, especially if there are many conditions to check. Clarity: The switch statement simplifies code condition handling.Advantages of the switch statement in PHP Whatever the current day is when executing this PHP code, it will be printed on the output. PHP switch statement exampleĬonsider the following PHP code as an example of the "switch" statement: ![]() Statement, but it is generally recommended for handling unexpected values. It is not necessary to include a default case in a switch If none of the specified cases match the expression, this code block is executed. If you omit this statement, the switch statement will continue to execute the code blocks of all subsequent cases, even if they do not match the expression. ![]() It instructs PHP to exit the switch statement and proceed to the next line of code after executing the case-specific code block. The "break " statement is used to end each case. Expressions can be any type ofĭata that can be compared, such as variables or function calls. The "switch (expression)" is the start of the switch statement, which evaluates the expression to determine which code block should be executed. block of code to execute if "expression" returns a value block of code to execute, if "expression" returns "valueN" block of code to execute, if "expression" returns "value3" block of code to execute, if "expression" returns "value2" block of code to execute, if "expression" returns "value1"
