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.
