PHP algorithm questions to be explored (Add code after implementation ...)

Print 0 only

The specific number is determined by the input parameter n.

If n = 5, 00000 is printed.

<? Php $ n = $ _ GET ['n']; for ($ I = 0; $ I <$ n; $ I ++) {echo "0" ;}?> // In the browser address field, enter n: eg ://......? N = 8Print n zeros Based on n values

Print a row 0101010101010101010101

The specific number is determined by the input parameter n.

Such as test. php? N = 3 Print 010

1 00 111 0000 11111

For if implementation

<? Phpfor ($ I = 0; $ I <10; $ I ++) {for ($ j = 0; $ j <= $ I; $ j ++) {if ($ I % 2 = 0) {echo '0';} else {echo '1' ;}} echo '<br/>' ;}?>For & if statement implementation

For switch implementation

While if implementation

While switch implementation

<? Php $ I = 0; while ($ I <10) {$ j = 0; while ($ j <= $ I) {switch ($ I % 2) {case 0: echo '0'; break; case 1; echo '1'; break;} $ j ++;} echo '<br/>'; $ I ++;}?>While & switch statement implementation

Make a calculator

Such as test. php? A = 1 & B = 2 & operator = jia output 3

Such as test. php? A = 5 & B = 2 & operator = jian output 3

Such as test. php? A = 2 & B = 5 & operator = cheng output 10

Such as test. php? A = 6 & B = 3 & operator = chu output 2
