It would be called twice - including possible side-effects of the function call happening twice. two conditions.Ī case where switch actually gives you a performance advantage is if the variable part is a function call: switch(some_func())
#Php switch code
It allows rapid case testing with a lot of different possible conditions, the code is also more readable. I'd also only use switch if there are more than e.g. In PHP, the Switch statement is very similar to the JavaScript Switch statement (See this JavaScript switch statement guide to compare and contrast). String tableName switch(PARAM): case Value1: tableName fooTable break. You can use either stristr() or strstr().The reason I chose to use stristr() in this case is simply because it's case-insensitive, and thus, is more robust. PHP use PDO with strongly typed parameterized queries (using bindParam()). if / else if / else is more flexible (hence better), but switch is slightly faster because it just computes the condition once and then checks for the output, while if has to do this every time. switch statement with multiple cases which execute the same code. General rule is use switch whenever the number of conditions is greater than 3 (for readability). SWITCH-statement two case with same condition and also different condition.
PHP- Switch case statement with conditional switch. However, if all your conditions are of the type x = value with x being the same in every condition, switch usually makes sense. Based on this question and this answer, the solutions I've come up with (while still using a case select) are below. PHP switch statement with same value in multiple cases. or switch is mainly a matter of preference.
