Thanks for that I did change the script to

echo "OK";

while testing in command line using :
/usr/bin/php myaclhelper.php
Each time I press enter it returns OK, it keeps running and does not
exit. However in squid log I get :
The MyAclHelper helpers are crashing too rapidly, need help!
What I think is wrong is that I need to identify what needs to handle
the script, I.e. how does squid know this is a php script and not a
perl script ?
Squid doesn't know. Squid passes the command line you configured in
external_acl_type to the OS.
The external_ac_type directive definition is:
external_acl_type <options> <%FORMAT codes> <command line>
Looking at your mail, I see you are testing with a different command
line syntax than the squid.conf contains.
You will get the same crash/abort that Squid sees if you ran the command
line:
/etc/squid/myaclhelper.php
NOTE 1: To run a script without specifying the interpreter on the
command line you need to add "#!/usr/bin/php" as the first line.
NOTE 2: also be aware that PHP is not a good language for Squid helpers.
PHP has a number of built-in timeouts (on std I/O sockets, on script
run-time, and on Zend engine run-time) which automatically shut down the
helper at various times from 30 seconds after starting to every hour.
These sudden shutdowns can also cause Squid problems.
