The following is a simple example of php process control switch. I think this is quite good. now I will share it with you and give you a reference. Let's take a look at the small Editor. switch allows multiple possible results of a scalar (expression) to be selected.
Syntax:
Switch (expr) {case result1: statement1 break; case result2: statement2 break ;...... Default: statement}
The system calculates the expr value and selects the following execution statement based on the calculation result (result1, result2, etc.). If all the case results do not match, the statement in default is executed.
Example:
<? Php switch ($ x) {case 0: echo "x equals 0"; break; case 1: echo "x equals 1"; break; case 2: echo "x equals 2"; break; default: echo "x is neither 1 nor 2 nor 0" ;}?>
Prompt
• Multiple case conditions can be judged.
• The results after case are not limited to numbers, but can also be characters or other types supported by PHP
• Default is not required
The simple example of the above php process control switch is all the content shared by the editor. I hope you can give me a reference and support me a lot.
