Usage and difference of the continuebreakreturn function-PHP source code

Ec (2); * $ i5; & nbsp; copy the code $ sum0; for ($ j0; $ j & lt; 10; $ j ++) {& nbsp; if ($ j $ I) & nbsp ;{& nbsp; & nbsp; break; & nbsp ;}& nbsp; else & nbsp ;{& nbsp; & nbsp; $ sum + $ j; & nbsp;} script ec (2); script

*/
$ I = 5;

The Code is as follows:
$ Sum = 0; For ($ j = 0; $ j <= 10; $ j ++) { If ($ j = $ I) { Break; } Else { $ Sum + = $ j; } }

Echo $ sum; // 10

The Code is as follows:
$ ContinueSum = 0; For ($ I = 0; $ I <= 10; $ I ++) { If ($ I = 5) { Continue; } Else { $ ContinueSum + = $ I; } }

The Code is as follows:
Echo $ continueSum; // 50 $ A = 2; If ($ a = 2) { Return $ s = 8; } Else { Return $ s = 9; }

Echo $ s; // nothing. Let's write it as a function.

Echo sv ($ a); // lost 10

The Code is as follows:
Function sv ($) { If ($ a = 2) { Return 10; } Else { Return 11; } }
