I wish I could see what's happening, but I have no way of ever knowing
what's going on

if {[catch [exec $valPHPPath -q << $php] errMsg]} {
puts "!!error in exec: $errMsg!!"
} else {
puts "This is your list!"
return "This is your list: $errMsg"
}

produces:

Status: 404 X-Powered-By: PHP/4.4.4 Content-type: text/html No input
file specified. child process exited abnormally while executing "exec
$valPHPPath -q << $php" (procedure "XML_GET_ALL_ELEMENT_ATTRS" line 37)

It is not even performing "puts" in either case, so I am not apparently
even catching the error, or I have no idea what's going on!
