Solution 1

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.

Solution 2

I added following line on top script to get it working for me

#!/usr/bin/php -q

Solution 3

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.

./hello_world.php did not work, but php hello_world.php worked.

./hello_world.php must work to get it executed by asterisk, you should adjust the shebang to the binary that is used by php, which you can see by executing which php and make sure it is executable.

[arheops]

check that you have /usr/bin/text2wave and it is exutable.

[AWippler]

I do. text2wave --help text2wave [options] textfile Convert a textfile to a waveform

[AWippler]

I have /usr/bin/php and /usr/bin/php5. php is a link to php5.

[pce]

try #!/usr/bin/env php and is hello_world.php executable? I updated my answer, try a alternative wrapper.

[arheops]

have you checked selinux? have you tried DISABLE it? that vary depend of your OS, usualy /etc/sysconfig/selinux (need restart after change)

[AWippler]

The host is debian. SELinux is not enabled.

[arheops]

try do following: 1) stop asterisk. 2) start it using "asterisk -vvvc" 3) agi set debug on, 4) re-check output.
