if help

[davelearning]

This may sound a bit stupid, but I cant get an if statement to work!

 

I can get it to run if the answer is a number, eg

 

if($variable=="1")
{
}

 

but what if its a word?

 

eg

 

 

 

if($variable=="hello world")
{
}

 

I cant get this to work!

 

Cheers

Are they the same including spelling, capitalization, and white space? 'Hello World' does not equal 'Hello world', or 'Hello World ' . . .

if it's an integer i am pretty sure you don't need those " " around it either.

if ($x == 1) {
  echo 'x is 1';
}

Thanks for the replies

Yup exactly the same

if ($x == 1) {
  echo 'x is 1';
}

 

I wasnt sure, it works with them in!

They can't be the same. What does var_dump($variable); return?

 

As far as quoting numbers, a number can also be a string. When using the == comparison, PHP's type-juggling will show 10 and "10" to be the same. If you compare them with the identical comparison === operator, it will not.

 

$str = '10'
if( $str == 10 ) { // returns TRUE
if( $str === 10 ) { returns FALSE

ehhm,

 

they are the same and it does work...

 

The insert query I had the created $variable contained the error

 

I should have just echoed out my variable

 

Dunce hat on head....
