Re: [PHP] if syntax using multiple conditions
Thanks! And, *wow* yes I just did try php2asp. Pretty good translation, although a few things need adjusting, it seems to do a remarkable job. I'll definitely have to play with it some more. :) -Brian -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Both are valid. First example will validate if both condition1 and
condition2 evaluate to true (they're set, and not null or false, etc.).
Second example will validate if condition1 evaluates to true AND EITHER
condition2 OR condition3 evaluate to true

Looks good to me.

I'd use a regular expression so as to match all those symbols with one
command. Check out eregi() or maybe strstr().

both examples you have given are valid but their logic is slightly
different.
example:
if ( condition1 && condition2 ) {
dothis;
}
if ( condition1 && (condition2 || condition3) ) {
dothis;
}
I am trying to translate this from asp to php:
how about using the asp2php program?

[PHP] if syntax using multiple conditions
What is the proper syndax in an if statement for containing multiple conditions?
example:
if ( condition1 && condition2 ) {
dothis;
}
if ( condition1 && (condition2 || condition3) ) {
dothis;
}
I am trying to translate this from asp to php:
If WhichAction = 7 And (InStr(filename, "\") Or InStr(filename, "/") Or
(Left(filename, 1) = chr(32)) Or InStr(filename, "*") Or InStr(filename, "?") Or
InStr(filename, "|") Or InStr(filename, "<") Or InStr(filename, ">") Or
InStr(filename, ":") Or InStr(filename, ) Or InStr(filename, "'")) Then
messages = "Bad filename"
filename = ""
WhichAction = 0
End If

This will certianly give a parse error, your sample should be:
if ($var == 1)
echo "Var equals 1";
else
echo "Var does not equal 1";

Again, the sample should look like (but ofcourse this one does not work):
if ($var == 1)
echo "Var equals ";
echo "1";
else
echo "Var does not equal 1";

Re: [PHP] if syntax
Hmm. I should read a bit further myself! I did not know about the colon indicating that there can be many statements before "else" or "endif". I've learnt something as a result, thanks. I should do some more engaging brain before keyboard!

Re: [PHP] if syntax
Alexander, The thing to do is to try it yourself. Yes its OK for single statements (I assume the colon after the "$condition):" is a typo. The first two examples in the manual (Chapter 11, if) show this syntax though not with "else". HTH Chris Alexander Ross wrote: > >if($something): > ... >else: >... > >Is that also correct??

Re: [PHP] if syntax
OK...
This is another easy question that everyone has an answer for.
Here's mine
:D
the if statement has many ways of being formed.
1 line code: (Echo or exit command)
if(empty($Variable))
exit;
else
echo "Variable exists
Multiple line code:
if(empty($Variable))
{
header("Location: Here.com");
exit;
}
else
{
echo "Valid variable";
eixt;
}
Combined:
if(empty($Variable))
echo "Variable empty";
else
{
Header("Location: Here.com");
exit;
}
or the other alternative
(empty($Variable)) ? echo "Empty" : echo "Contains Something";

Re: [PHP] if syntax
There are no brackets necessary if you only have one line of code to be executed in
the case. For example:
if($var == 1)
echo "Var equals 1";
} else {
echo Var does not equal 1";
}
But this is not valid:
if($var == 1)
echo "Var equals ";
echo "1";
} else {
}

I know this is correct:
if ($something)
{
...
}
else
{
...
}
But I recently saw someone use this instead:
if($something):
...
else:
...
Is that also correct?? No brackets needed?

This will only work if you have a single line of code after the else and
if. At least that is my understanding of all languages :)
