    global variables, Apache, PHP4.4.1Win32, WinXP

    How do I get a function to see a global variable without employing
    a parameter list?

    The source code:

    <html><head>
    <title>Simple Global Variable / Function Test</title>
    <?php
    $counter_file = "counter.tx t"; // global variable

    //quickquote function
    function qq($sQuoteMe, $sQuoteChar) {
    return("$sQuote Char$sQuoteMe$s QuoteChar");
    }

    function updatecount() {
    echo('<p>$count er_file = ' . "$counter_f ile</p>\n");
    }
    ?>
    </head>
    <body><?php
    echo('<p>$count er_file = ' . qq($counter_fil e, "&quot;") . "</p>\n");
    // echo('Hits: ' . qq("qq test", '&quot;'));
    echo('<p>Hits: ' . qq(updatecount( ), "&quot;") . "</p>\n");
    ?></body></html>

    ... echos the following HTML to the browser ...

    <html><head>
    <title>Simple Global Variable / Function Test</title>
    </head>
    <body><p>$count er_file = &quot;counter.t xt&quot;</p>
    <p>Hits: &quot;&quot; </p>
    </body></html>

    Thanks.

      I put my vote in for the

      Option Explicit '(.asp/vbscript) (use strict //perl)

      as a requested improvement.

      Only 17 votes there right at the moment. If anyone else would like
      such an improvement, go to the link above and vote.

          Well if you set your error level thingy to E_ALL it'll throw a notice
          if you use a variable that you haven't instantiated. But instantiation
          basically means 'setting'. So you can do this code:

          <?php

          $counter = 3;

          $countr = $counter + 1; // notice the error (and i only didn't use
          $countr++ because that might actually throw the notice)

          echo $counter;

          ?>

          and it won't throw a notice as you're using the NEW $countr variable in
          a setting sense. However it does help you a little with regards to
          CHECKING a variable, e.g.:

          <?php

          $counter = 3;

          echo $countr;

          ?>

          that should throw a notice with errors at E_ALL.

          But that's nowhere near a nice Option Explicit.

              Heh just read that page you linked to and it's totally explained there.
              Probably better than I did too.
