Copy Code code as follows:
<?php
/**
* Use $ARGC $argv Accept Parameters
*/
echo "received {$ARGC} parameters";
Print_r ($ARGV);

[0] => test.php
)
[root@dell113 lee]#/usr/local/php/bin/php test.php a b c D
5 parameter array received
(
[0] => test.php
[1] => a
[2] => b
[3] => C
[4] => D
)
[Root@dell113 lee]#
second, using the Getopt function
Copy Code code as follows:
<?php
/**
* Using the GETOPT function
*/
$param _arr = getopt (' a:b: ');
Print_r ($param _arr);

Copy Code code as follows:
[root@dell113 lee]#/usr/local/php/bin/php test.php-a 345
Array

[A] => 345
)
[root@dell113 lee]#/usr/local/php/bin/php test.php-a 345-b 12q3
Array
(
[A] => 345
[b] => 12q3
