Re: [PHP] Session: I RTFM

2002-12-15 Thread Marco Tabini

Single quotes are normal strings. Double quotes are strings in which
substitutions can take place. For example:

?php

$a = 'test';

echo '$a';  // outputs $a
echo $a;  // outputs test

?

Double quotes also expand escape strings (e.g.\n) whereas single
quotes don't.

Cheers,


Marco

What is the difference between:
$familyname = getvar(familyname);
and
$familyname = getvar('familyname');

What do single quotes do, as a general rule, that double cannot (he asks remembering 
something, but not sure what)?

 // You don't need session_register anymore

 $familyname = getvar('familyname');

 and so on--just one line per variable.

 Hope this helps.

 Sessions depends on a number of factors
 including your version of PHP and the setting of register_globals.

 The FM manual says:

 $_SESSION (or $HTTP_SESSION_VARS with PHP 4.0.6 or less) is recommended

 So I am using PHP Version 4.1.2 (and 4.2.3 on my localhost to test offline)

 Ok. I quit using $HTTP_POST_VARS[familyname].

 With a little rethinking, I have this working, I hope.

 Now ... is there a cleaner way to assign my variable familyname?

 Pseudo code:

 if _post[familyname] exists set session variable
  (no sense in setting it until I post it)
 if _session[familyname] exists, $familyname = $_SESSION[familyname];

 I'll have about 30 variables. Going to be alot of lines. There must be an easier, 
cleaner way?

 ?php
 #session_name(TestALS);
 session_start();

 if (isset($_POST[familyname]))
 {
 session_register(familyname);
 $familyname = $_POST[familyname];
 echo Yay: \$familyname= $familynamebr;
 }

 if (isset($_SESSION[familyname]))
 {
 $familyname = $_SESSION[familyname];
 echo yay session works, \$familyname= $familynamebr;
 }

Re: [PHP] Session: I RTFM

2002-12-14 Thread Justin French

John,

PHP looks for $vars or {$vars} to parse in the string when double quotes
are used... whereas when single quotes are used, it won't parse/substitute
the vars.

?
// works:
echo My favourite fruit is {$fruit};
echo My favourite fruit is $fruit;
echo 'My favourite fruit is '.$fruit;

// doesn't work:
echo 'My favourite fruit is {$fruit}';
echo 'My favourite fruit is $fruit';
?

So, when you're not using $vars, using single quotes will be marginally
faster... perhaps not important on small sites, but very important on big
ones, and a decent habbit to get into :)


Justin
