The Exec Format Error is from /bin/bash, asterisk executes hello_world.php as a bash script.
shebang
If you add a correct shebang, the script get executed by the given PHP intepreter. The first Line tells the System which program should run the script.
#!/usr/bin/env php
To test your shebang, execute the script itself, not by PHP:root@asterisk-test:/var/lib/asterisk/agi-bin# ./hello_world.php
Make sure it is executable with:root@asterisk-test:/var/lib/asterisk/agi-bin# chmod +x hello_world.php
alternative wrapper
Create a bash script that executes the PHP script.
example hello_world.sh:/usr/bin/php hello_world.php
and call it in the Dialplan AGI("hello_world.sh").
Make sure the shellscript is executable chmod +x hello_world.sh.

I added following line on top script to get it working for me
#!/usr/bin/php -q

You issue is not asterisk issue,but general linux one.
Please try from your command line following:
su asterisk -c "/var/lib/asterisk/agi-bin/hello_world.php"
Most likly reasons: php path is incorrect or selinux enabled and not configured.

Could you check your extensions.conf or extensions_custom.conf, if the extension and priority are not continuous also this error will occur.
please check the below example:
[context]
exten => 1,1,Answer()
exten => 1,2,AGI(your-agi-script)
exten => 1,3,Hangup()
