php cli 方式 在crotab中运行解决

/var/www/html/bt/e/btsys:.:/usr/share/pear:/usr/share/phpphp warning: require(../class/connect.php): failed to open stream: no such file or directory in /var/www/html/bt/e/btsys/torrents-scrape.php on line 17
php fatal error: require(): failed opening required '../class/connect.php' (include_path='/var/www/html/bt/e/btsys:.:/usr/share/pear:/usr/share/php') in /var/www/html/bt/e/btsys/torrents-scrape.php on line 17

尝试解决方法1 加入如下代码

代码

// setting include path
$cur_dir=getcwd();
$cur_dir=$basedir = dirname(__file__);
$path = ini_get('include_path');
ini_set("include_path", "$cur_dir:$path");
$path = ini_get('include_path');
//echo $path;
require(../class/a.php)
require(../class/b.php)
...............

运行失败

尝试解决方法2 加入如下代码

$cur_dir = dirname(__file__);
chdir($cur_dir);
require(../class/a.php)
require(../class/b.php)

运行成功
总结: 在require 时，如果是相对目录，在crontab 中运行php脚本，要进入到脚本所在目录才可以
