php命令行写shell应用

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。

php -h

Usage: php [options] [-f] <file> [--] [args...]
   php [options] -r <code> [--] [args...]
   php [options] [-B <begin_code>] -R <code> [-E <end_code>] [--] [args...]

  -a               Run as interactive shell
  -c <path>|<file> Look for php.ini file in this directory

  -F <file>        Parse and execute <file> for every input line
  -E <end_code>    Run PHP <end_code> after processing all input lines

  -z <file>        Load Zend extension <file>.
 
  args...          Arguments passed to script. Use -- args when first argument
                   starts with - or script is read from stdin
 
  --ini            Show configuration file names
 
  --rf <name>      Show information about function <name>.
  --rc <name>      Show information about class <name>.
  --re <name>      Show information about extension <name>.
  --rz <name>      Show information about Zend extension <name>.
  --ri <name>      Show configuration for extension <name>.

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

<?php
for($i=0;$i<10;$i++){
   echo $i;
   echo '\n';
}
?>

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
<?php
for($i=0;$i<10;$i++){
   echo $i;
   echo " java-er.com \n";
}
?>

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
<?php
for($i=0;$i<360;$i++){
   echo $i;
   sleep(10);
   echo " java-er.com \n";
}
?>

3. 外部传入参数

#!/usr/bin/php
<?php
    var_dump($argc); //返回参数总个数
  var_dump($argv);
 
exit;
?>

./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"
}
