better PHP config

[GoogleCodeExporter]

I found the php.nanorc's out there lacking, so here's mine. Still working
on it but it's fairly good for daily use, at least for me.

Thanks.

#override not malformed
color brightmagenta start="['"]" end="[^\\]['"]"

## functions
icolor white start="[a-z_0-9]+\(" end=")[\);,$]*"

## variables
icolor brightred "\$[a-z_0-9]+"
color brightred start="\$\{" end="\}"

color green "([^\$]|^)\<(var|float|global|double|bool|char|int|enum|const)\>"

## constants (assume constants are ALL_CAPS)
color red "\<[A-Z_0-9]*\>"

## numbers
#decimal
color yellow "\<\-?[0-9\.]+\>"
#hex

#octal
color yellow,green "\<0[0-7]+\>"
#boolean
icolor cyan "([^\$]|^)\<(true|false)\>"

#kind of a hack here since backrefs don't work with start and end apparently
