JAVA和PHP语法对比 - 数组循环

• java语法

$a = [9, 5, 6, 4, 10];

sort($a);

array_walk($a, function($v) {   
 echo $v;
});

$b = ["a", "A", "b", "B"];

sort($b);

array_walk($b, function($v) { 
   echo $v;
});

• PHP语法

int[] a = {9, 5, 6, 4, 10};

Arrays.sort(a);

for(int i = 0; i < a.length; i++) {  
    System.out.println(a[i] + "\t"); 
 }  

String[] b = {"a","A", "b","B"};

Arrays.sort(b);

for(int i = 0; i < b.length; i++) { 
    System.out.println(b[i] + "\t");  
}
