Below is my full previous code

PHP Code:
#!/bin/bash

# Load average ALERT value.

# Maximum load injection trigger
max_loadavg=15.0

# Minimum load injection trigger
min_loadavg=10.0

loadavg=$(cat /proc/loadavg | awk '{print $1}')

# Grab Web1 current LOAD
VAR1=$(cat /proc/loadavg | awk '{print $1}')

# Grab Web2 current LOAD
VAR2=$(ssh web2 -C cat /proc/loadavg | awk '{print $1}')


# To check current LOAD for both Database value and trigger the injection
if [ $(echo "$VAR1 >= $max_loadavg && $VAR2 >= $max_loadavg"|bc) -eq 1 ]

then

EXECUTE THE CODE

fi

# To check current LOAD for both Database value and trigger the injection
if [ $(echo "$VAR1 <= $min_loadavg && $VAR2 <= $min_loadavg"|bc) -eq 1 ]
