Answer by pa4080 for Call and run php script from shell script

Usually the command php is used for interpretation of PHP scripts in the shell.

$ php /path/script-name.php

I made simple test.sh and it works:

$ cat ./text.sh
#!/bin/bash
sudo php /var/www/wiki/maintenance/update.php

$ chmod +x ./test.sh
$ ./test.sh

It works.

After that I made complicated script as your example:

$ cat ./text.sh

#!/bin/sh

LIST=/var/www/wiki/maintenance
CONFIG=/usr/bin/php

for i in $LIST
do
    ${CONFIG} ${i}/update.php
done

$ sudo ./test.sh

It works!

$ cat ./text.sh

#!/bin/sh

LIST="/var/www/wiki/maintenance"
CONFIG="/usr/bin/php "

for i in $LIST
do
    ${CONFIG}${i}/update.php
done

$ sudo ./test.sh

Works also!
