else function

[anarchy3200]

is it possible to have more than one if, one elseif, and one else in a script - can you have more than three functions like this in one statement?

thanks

Huh?

I'm not sure I understand, but this is valid PHP if it means anything:

if(true) {
 if(true) {
  ...
 }
 else if(true) {
  ...
  if(true) {
   ...
  else {
   ...
  }
 }
 else if(true) {
  ...
 }
}
else {
 ...
} 

The combinations are infinite. An if doesn't need an else, or an else if or anything; they are optional.

Hope that helps,
Sadiq.

my script is below:

 <?php

if ($_GET["name"] == comp){
    echo "<img src=\"pics/1.gif\" align=texttop>";
}

elseif ($_GET["name"] == lap){
    echo "<img src=\"pics/2.gif\" align=texttop>";
}

else{
    echo "Please enter a valid place";
    }
?>

i currently have an if,else and elseif but if i put in more than one i am getting errors - is there a way to do this and give more option for the script?

In situations like this you may want to consider using the switch statement, which is similar to a series of IF statements on the same expression:

switch ($_GET["name"]) {
case "comp":
   $pic=1;
   break;
case "lap":
   $pic=2;
   break;
default:
   $pic="defaultimage";
}

echo "<img src=\"pics/$pic.gif\" align=texttop>";
