In this program, we are first declaring an array containing a collection of letters. Then byusing a foreach loop, we are printing all the elements of the array one by one. An if the conditional statement is introduced to break the loop once the value of array pointer reaches the letter ...
This statement allows you to stop the execution of the current loop or switch structure. This allows you to break out and continue running the script. For example, if you find the data you need in a loop, you can break out of it rather than waiting for the loop to complete. ...
VAR 一种PHP内的变量,大多数情况下表示的是单条opline的返回值,但是并没有显式的表现出来,列如在if判断语句包含某个函数的返回值,if(random()){},在这种情况下random()的返回值就是VAR变量类型。 CV变量,是在php代码里面显式的定义的出来的变量例如$a等。
<?phpif($argc!=2){echo"Usage: php hello.php [name].\n";exit(1);}$name=$argv[1];echo"Hello,$name\n"; PHP 会在脚本运行时根据参数设置两个特殊的变量,$argc是一个整数,表示参数个数,$argv是一个数组变量,包含每个参数的值, 它的第一个元素一直是 PHP 脚本的名称,如本例中为hello.php。
if (false === $data) {return isset($default) ? $default : null;}}}if (!empty($type)) {switch (strtolower($type)) {case 'a': // 数组$data = (array) $data;break;case 'd': // 数字$data = (int) $data;break;case 'f': // 浮点$data = (float) $data;break;case 'b':...
Warning:If you omit thebreakstatement in a case that is not the last, and that case gets a match, the next case will also be executed even if the evaluation does not match the case! Example What happens if we remove thebreakstatement from case "red"?
Example of break statementBelow is an example of PHP break statement.<?php for ($i = 1; $i <= 10; $i++) { if ($i == 5) { break; } echo $i . ""; } ?> The output of the above example is:1 2 3 4 In this example, the loop will terminate when the value of $i beco...
