Multi-variable if statements

[lice200]

what I want is two variable's in a single if statement. The only thing is I cannot make it work the way i have it. I do not want to have 7 if statements if possible.

[code][code=php:0]
<?php
$day = Sat;

if ($day = ('Sat', 'Sun')) {
echo "It is the weekend!";
}
?>
[/code][/code]

This works, use || as OR.

[code]<?php
$day = Sat;

if ($day = "Sat" || "Sun") {
echo "It is the weekend!";
}
?>[/code]

You can also use the [url=http://www.php.net/in-array]in_array()[/url] function.

[code]<?php

$week_days = array("Mon", "Tue", "Wen", "Thu", "Fri");
if(in_array($day, $week_days))
echo "Regular day";

?>[/code]

Orio.

To Mutley: Did you try your solution? It does not work, since the syntax is incorrect. The correct syntax is:
[code]<?php
$day = 'Sat';
if ($day == 'Sat' || $dat == 'Sun')
  echo 'Its is the weekend';
?>[/code]

I tried it and it worked, unless it echoed it by default error.

That's because the value "Sun" is true (always). I mean- even if you set the value of $day to "foo", the statement will be true.

As said in the manual, in the section about booleans (link [url=http://www.php.net/manual/en/language.types.boolean.php]here[/url]):
[quote] When converting to boolean, the following values are considered FALSE:
-the boolean FALSE itself
-the integer 0 (zero)
-the float 0.0 (zero)
-the empty string, and the string "0"
-an array with zero elements
-an object with zero member variables (PHP 4 only)
-the special type NULL (including unset variables)
-SimpleXML objects created from empty tags

Every other value is considered TRUE (including any resource).[/quote]

Look at the last line ;)

Orio.
