Ok this is what I did:

[TCL]
set contentsList [exec $valPHPPath << $php]; # $valPHPPath IS THE PATH
TO "php"
[/TCL]

And here is the error message I now get:

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 << $php" (procedure "XML_GET_ALL_ELEMENT_ATTRS" line 36)

I even tried a variant:

[TCL]
set contentsList [exec $valPHPPath << '[regsub -all {'} $php {\\'} php;
set php]']
[/TCL]

And got this error message

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 << '[regsub -all {'} $php {\\'} php; set php]'" (procedure
"XML_GET_ALL_ELEMENT_ATTRS" line 36)

And even this:

[TCL]
set contentsList [exec $valPHPPath << '<? print_r("Hello World"); ?>']
[/TCL]

To no avail, getting the following error message:

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 << '

I am not sure where to go going forward with this at this point, sorry,
you may have to make it a bit more simple for me to understand how to
make this work properly
