在PHP CLI下使用类似GET的方法传参

cli get linux php use method

Linux下为了方便,有时候会直接使用命令行的方式来执行php程序,比如一些crontab任务之类,但通常写出来的大部分php程序,都没有考虑到命令行下的一些情况,直接使用GET进行参数传递也是常态,但这在命令行下却很无奈,尤其是传递多个GET参数时,连命令都无

Linux下为了方便,有时候会直接使用命令行的方式来执行php程序,比如一些crontab任务之类,但通常写出来的大部分php程序,都没有考虑到命令行下的一些情况,直接使用GET进行参数传递也是常态,但这在命令行下却很无奈,尤其是传递多个GET参数时,连命令都无法正确执行——GET多参数分隔符&会妨碍命令的执行。

1、PHP CLI的参数传递方式

PHP CLI下参数的传递是使用Linux命令行的方式进行,将参数值按照指定的先后顺序依次排列,一旦顺序错误,最终传送的结果也将错误,而且,如果程序要支持命令行参数,还需要专门的分析和拆开$argv数组,如果是修改现有程序,工作量将会更大。

2、捕获参数,组装伪$_GET和$_REQUEST数组

命令行下是没有$_GET等变量的,但如果使用GET进行参数传递,程序中肯定会有对诸如$_GET和$_REQUEST数组的调用。如果要降低修改的工作量,最简单的办法就是,抓获CLI传递的参数,再将参数组装成一个$_GET和$_REQUEST数组。
为了避开cli中对参数的先后顺序的要求,让命令执行使用更容易分辨更让人熟悉的URL参数传递方式,可以按如下的格式来传递参数并捕获:

<p class="line">1</p>
Copy after login
Copy after login
<p class="line">php filename.php "name=Roges&height=187.96&weight=99.79"</p>
Copy after login
Copy after login

注意,命令行中使用&符号时,必须要将其用引号括住,否则你会有意外的惊喜。

3、实现

想到了过程,实现起来就比较简单了,一个比较简单的实现如下:

<p class="line">1</p>

Copy after login
<p class="line">// if file was executed by php cli, cli paramertes will be convert</p><p class="line">// to $_GET and $_REQUEST array.</p><p class="line">if(isset($argv) AND count($argv) </p><p class="line">    // GET paramertes are always follow the page url with ? symtax,</p><p class="line">    // it show be removed.</p><p class="line">    $argv[1] = str_replace("?", '', $argv[1]);</p><p class="line">    $params = explode('&', $argv[1]);</p><p class="line">    $_REQUEST = array();</p><p class="line">    foreach($params as $p) {</p><p class="line">        //get the location of the '='</p><p class="line">        $eq_loc = strpos($p, '=');</p><p class="line">        $_REQUEST[substr($p, 0, $eq_loc)] = substr($p, $eq_loc + 1, strlen($p) - $eq_loc);</p><p class="line">    }</p><p class="line">    $_GET = $_REQUEST;</p><p class="line">}</p>
Copy after login

将这个代码存储为文件,再在需要使用的文件头部进行引用即可。当在命令行下执行脚本时,使会进行转换,否则是不会进行任何操作的。

4、执行效果

将上面的代码保存然后在最后加上如下的两句,便可查看参数传递的效果:

<p class="line">1</p>

Copy after login
<p class="line">echo '$_REQUEST: ';</p><p class="line">print_r($_REQUEST);</p><p class="line">echo '$_GET: ';</p><p class="line">print_r($_GET);</p>
Copy after login

将文件命令为cli_get.php,在命令行中执行,结果如下:

<p class="line">1</p>
