我们可以在Bash脚本中使用PHP吗？

Question

I have a bash script abcd.sh

#!/bin/sh
for i in `seq 8`; do ssh w$i 'uptime;ps -elf|grep httpd|wc -l;free -m;mpstat'; done &
pid=$!
sleep 1
kill -9 $pid

I want to use PHP in my bash script.

eg: in bash script I want to set value of seq through PHP.

Mmm, if you are using bash, you should maybe use a bash shebang on line 1 so people know you are expecting bash features to be available. And if you are using bash, you can use a bash sequence anyway:

#!/bin/bash
for i in {1..8}; do echo $i; done

Update 1

If the number of servers is obtained through PHP, you can do something like this:

numservers=$(php -r 'echo 8;')
for i in $(seq $numservers); do echo $i; done
1
2
3
4
5
6
7
8

Update 2

Ok, you said the number of servers is dynamic, but then you say it is set in the script (which seems contradictory), but this is what you do:

numservers=10
for i in $(seq $numservers); do echo $i; done
1
2
3
4
5
6
7
8
9
10
