PHP and session variable substitution

In my experience of trying to do this, what I think is going on is this...

• Make customization including session variable

  $landingUri = '%{session.server.landinguri}';

• PHP executes when page is accessed, setting landingUri to the string

  %{session.server.landinguri}

  .
• As the processed HTML goes down the pipe to the client after PHP has executed, APM rewrites

  %{session.server.landinguri}

  to the

  /?pw=0

  (or whatever the value should be).
  • So if you were to

    echo

    the variable in PHP, the resulting HTML from the PHP perspective would be

    %{session.server.landinguri}

    , but further down the line, APM rewrites that within the HTML to the actual value.

All that to say, when you do the

strpos

%{session.server.landinguri}

/?pw=0

For me, the only way to overcome this kind of thing was to do testing within javascript instead, which may not be feasible depending on what you want to do.

Another option might be to use a policy agent event in the VPE to do some work and set a custom session variable you want to echo on the page and then use that instead.
