Several ways to pass in parameters when running in php command line mode
url method
<strong>$param = array(); if ($argc > 1) { parse_str ( $argv [1], $param ); foreach ( $param as $k => $v ) { echo "define $k=$v\n"; $param[$k] = $v; } } print_r($param); //运行示例 php sync_t_search.php "name=sjk&city=bj"</strong>
System built-in variables
<strong>//当传入多个或多个参数可选时有很大的局限性 $argv #0为当前执行的文件名 $argc #参数个数</strong>
System function getopt
<strong>//1、个人总结:如果只传一个参数,:(必选)/::(可选)都可 //2、如果传多个参数则要区分可选必选,建议尽量用可选参数并且后面的值不要传入空格 //3、可选参数:标识符存在且有值时,下标才会存在 //4、必选参数:只要标识符存在,下标就会存在(如果取不到值为false) /** * php song.php -h"a b" || php song.php -h"a b" 不受空格影响(建议保持一致都不加空格) array(1) { ["h"]=> string(3) "a b" } php song.php -h -a array(1) { ["h"]=> string(2) "-a" } */ var_dump(getopt('h:a::')); //必选参数,如果参加之间有空格要加引号, 选项后面有空格也不会影响取值,会把他后面的值都当做参数的值 /** php song.php -asong array(1) { ["a"]=> string(4) "song" } */ var_dump(getopt('a::h:')); //可选参数,参数必须紧跟在选项后面,否则获取不到</strong>
4. System function getopt
<strong>//标准输出 fwrite(STDOUT, "Enter your name: "); echo "\n"; //标准输入 $name = trim(fgets(STDIN)); fwrite(STDOUT, "Hello, $name!");</strong>
