php可以像java perl python 那样运行,今天发现如果我早早知道这个,或许我不会去学习java 和 python
当年学java不过为了一个程序放在服务器上,不停的跑啊跑,原来php也可以。

1.用php命令行的方式执行php脚本,例如/usr/bin/php test.php
缩写 php test.php
test.php
2.脚本开头第一行写上#!/usr/bin/php,然后可以把脚本设为可执行 chmod a+x test.php,之后就可以用命令行的方式直接执行脚本了,例如./test.php
#!/usr/bin/php
执行一小时,看看php会不会挂,我希望一个命令行可以跑到天荒地老
#!/usr/bin/php
3. 外部传入参数
#!/usr/bin/php
./test.php
int(1)
array(1) {
[0]=>
string(10) "./test.php"
}
./test.php a java php
int(4)
array(4) {
[0]=>
string(10) "./test.php"
[1]=>
string(1) "a"
[2]=>
string(4) "java"
[3]=>
string(3) "php"
}
