Need help with correct syntax for "if" condition

[capella07]

I'm trying to determine if a string is in a string, and if it is not, then do what's in the brackets.

 

Example:

I want to do something if the string "mobile" is not in the string "automobile". I know that strpos returns False if the substring isn't found in the main string, so I currently have something like the following in my code:

 

$bigstring = "automobile";
$littlestring = "mobile";
if( !(strpos($bigstring, $littlestring) ) {
// Do something
}

 

But it didn't seem right with the exclamation mark where it is.

 

If that's not the right way to do what I want to do, could someone provide an example of the right way?

 

Thanks in advance.

this should work

$bigstring = "automobile";
$littlestring = "mobile";
if( !strpos($bigstring, $littlestring) ) {
// Do something
}

you had an extra "("

Great!

 

Thanks for the help!

Actually, if LittleString is at the beginning of BigString, then strpos() will return zero which will evaluate to false.  So you need to check for equivalence:

 

if(strpos($bigstring, $littlestring) === false) {
// Do something

Thanks, David

 

Actually, as soon as I read taquito's reply I remembered I had something similar on another page, which also had the "=== false" in it.

 

Works like a charm!
