Info: To look into

handy little bit of code I wrote to take arguments from the command line and parse them for use in my apps.

<?php

 $i = implode(" ",$argv); //implode all the settings sent via clie
 $e = explode("-",$i); // no lets explode it using our defined seperator '-'

       //now lets parse the array and return the parameter name and its setting
       // since the input is being sent by the user via the command line
       //we will use stristr since we don't care about case sensitivity and
       //will convert them as needed later.

    while (list($index,$value) = each($e)){

       //lets grap the parameter name first using a double reverse string
       // to get the begining of the string in the array then reverse it again
       // to set it back. we will also "trim" off the "=" sign

     $param = rtrim(strrev(stristr(strrev($value),'=')),"=");

       //now lets get what the parameter is set to.
       // again "trimming" off the = sign

     $setting = ltrim(stristr($value,'='),"=");

       // now do something with our results.
       // let's just echo them out so we can see that everything is working

      echo "Array index is ".$index." and value is ".$value."\r\n";
      echo "Parameter is ".$param." and is set to ".$setting."\r\n\r\n";

}

?>

when run from the CLI this script returns the following.

[root@fedora4 ~]# php a.php -val1=one -val2=two -val3=three

Array index is 0 and value is a.php
Parameter is  and is set to

Array index is 1 and value is val1=one
Parameter is val1 and is set to one

Array index is 2 and value is val2=two
Parameter is val2 and is set to two

Array index is 3 and value is val3=three
Parameter is val3 and is set to three
