由于它在文件中，您可以迭代为：

from shipping_infos si
inner join orders o
on si.user_id = o.user_id inner join products p on p.product_id =

where si.user_id='".$user_id."';";
$run_receipt_checking = mysqli_query($con, $check_receipt);

首先让我们将文本写入文件：
str =<<BITTER_END
command[check_users]=/usr/local/nagios/libexec/check_users -w 30 -c 35
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command[check_disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda1
command[check_hda]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sdb
command[check_procs]=/usr/local/nagios/libexec/check_procs -w 200 -c 250
BITTER_END
Fname_in = "in"
Fname_out = "out"
File.write(Fname_in, str)
#=> 390
现在将该文件读入字符串，修改字符串并将其写入输出文件：
File.write(Fname_out, File.read(Fname_in).gsub("/dev/sdb", "/dev/xvda1"))
#=> 392
让我们确认它有效：
puts File.read(Fname_out)
command[check_users]=/usr/local/nagios/libexec/check_users -w 30 -c 35
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command[check_disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda1
command[check_hda]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/xvda1
command[check_procs]=/usr/local/nagios/libexec/check_procs -w 200 -c 250
