By returning a value in an if statement (and anywhere else in a function really), you:

1. terminate the function that the if-statement is in (when the if-statement is executed);
2. can treat everything outside that if statement as the else statement; i.e:
   
   PHP код:

   someFunction() {
    if(someCondition)
        // Terminate the function 
        return true;
    // code under this is ONLY executed when that if statement evaluates to false, thus it can be considered the 'else' statement for that if statement.
    return false;
} 

   One could debate that, if the return value in the if statement is the same as the function's end return value, then the else statement should be used:
   
   PHP код:

   someFunction() {
    if(someCondition)
        // Terminate the function 
        return true;
    // code
    return true; // return value is true which is the same as in the if block
} 

   PHP код:

   someFunction() {
    if(someCondition) {
        // code 
    }
    else {
        // code
    }
    return true;
} 


I think that's what you meant.
