Trying to use $_SERVER['PHP'] ?

[Mike-2003]

I was trying to use the $_SERVER['PHP'] because I heard it was a good Idea to keep globals off. I have tried it in the below, but it does not seem to work. All I want it to do is go back to the home page. Any help would be appreciated.

Thanks!

echo "<p><hr size=0 color='#cccccc'>";
                echo "<center>";
                echo "<font class='text10'>[ ";
				echo "<a href=" .$_SERVER['PHP_SELF'] . "' class='text10'>Home</a> ] ";
                echo "<br>";
                echo "<p><br>&nbsp;";
                echo "</center>";

PHP_SELF is the name of the current script, not necessarily the "home" page. Use PHP_SELF to have a script call itself no matter what it is named.

Your problem may be with some extra quotes, try this:

echo '<center>';
echo '[ ';
echo '<a href="'.$_SERVER['PHP_SELF'].'" class="text10">Home</a> ] ';
echo '<br />';
echo '<p><br />&nbsp;</p>';
echo '</center>';

PS. Font tags are evil. Use style sheets.

yeah what he said

try using <div align="center" class='text10'>

Where text10 is the name of a class that you create

I tried what was suggested, but it still does not work. Any other suggestions?

Thanks.

Assuming the "home" page is just the index of the current directory, just use dirname($_SERVER["PHP_SELF"]).

Also, he is using style sheets--the font tag is there for only the class definition. The DIV method is a much worse way to do it, as it will be ignored by browsers that do not support layers (NS<6, IE<4, etc). The best things he could use are either <font> or <p>.

I tried the last suggestion, but it did not work. When I put the following code in it works fine, I thought I should replace the $PHP_SELF with the $_Server['PHP_SELF'] with globals turned off, is that correct?
Thanks.

echo "<p><hr size=0 color='#cccccc'>";
                echo "<center>";
                echo "<font class='text10'>[ ";
                echo "<a href='" . $PHP_SELF . "' class='text10'>Home</a> ] ";
                echo "<br>";
                echo "<p><br>&nbsp;";
                echo "</center>";
                echo "</td></tr></table>\n";
                echo "</body>\n";
                echo "</html>\n";

Maybe you could try:

echo '<p><hr size=0 color="#cccccc"><font style="text-align: center;" class="text10">[ ';
echo '<a href="' . $_SERVER['PHP_SELF'] . '" class="text10">Home</a> ]';
echo "</font></p><br><p>&nbsp;</p><br>&nbsp;</td></tr></table>\n</body>\n</html>";

if you wanted to use $_SERVER
Also, what version of PHP are you using?
In too early a version you should use $HTTP_SERVER_VARS instead, but the exact functionality would then differ.

Well Mordecai, the problem is that <font> is deprecated, and sometimes using <p> doesnt quite fit.

[Mike-2003]

I tried the suggestion, but it comes up with the index of the site. The other one I use takes you back to the main page.

Also I'm using PHP version 4.0.5.

Thanks.

[laserlight]

Try using $HTTP_SERVER_VARS['PHP_SELF'] then.

actually, with PHP 4.0.5 it doesnt provide much advantage except to be more sure that the variable is coming from the server variables.

[Mike-2003]

Thanks! laserlight, it worked 😃 .

Does that mean $_SERVER['PHP'] is used with a newer version of PHP?

[laserlight]

Yes, it (and the other $_* type of predefined variables) were introduced in PHP 4.1.0
