//编译过程:这里必须输入java文件的全路径
exec("javac D:\\test.java");
//运行并重定向输出,这里必须要set classpath,然后重定向的路径也要是全路径
$res = exec("set classpath=D:\\&java test < D:\\in.txt > D:\\out.txt", $out, $status);
//打印出的状态值,如果是0表示成功,1表示失败
var_dump($status);
//如果不是重定向,那么res将会用一个数组来保存
//System.out.println()的输出内容
print_r($res);

test.java源文件如下:

import java.util.*;
public class test
{
	public static void main(String[] args) {
		System.out.println("java php");
		Scanner in = new Scanner(System.in);
		for(int i = 0; i < 10; i++) {
			int n = in.nextInt();
			System.out.println(n);
		}
	}
}

以上就介绍了PHP编译执行Java源文件并重定向输出,包括了java,源文件方面的内容,希望对PHP教程有兴趣的朋友有所帮助。
