Now I get this error:
couldn't execute "php": no such file or directory
When I try this:
[TCL]
set cannotRunPHP [catch {exec exec php << $php >@stdout 2>&stderr}
errorMsg]
if {$cannotRunPHP} {
puts $errorMsg
return {}
} else {
if {![IS_LIST $contentsList]} { set contentsList [split
$contentsList] }
if {[llength $contentsList] == 0} { lappend contentsList {?} }
return [lrange $contentsList [expr {[lsearch -exact $contentsList
"?"] + 1}] end]
}
[/TCL]
Wow this should only take an hour, it's taken 3 days so far!
