Is there a more efficient way to code this conditional statement? Is there a max number of conditionals in PHP?

With these it helps That syntax isn't valid but PHP offers a bunch of different ways to go about this anyway.
But you can use in_array() to make this more concise:
code :
if (in_array($currentLetter, [0,1,2,3,4,5,6,7,8,9])) {

}
if (in_array($currentLetter, range(0,9))) {

}
if (ctype_digit($currentLetter)) {

}

like below fixes the issue To quote from Framework Design Guidelines in the section about "General Style Conventions" this is said about braces:

Efficient approach for multiple 'or' statements in an conditional statement

it should still fix some issue Only a few months into learning Python, so bear with me... , You could do something like:
code :
def enter(self):
    print "What's up? Get in the Bran Muffin car!"

    action = raw_input(">  ")

    if(action == "shut up chip" or action == "go away dude" or action == "screw you"):
        print "Screw you!"
        print action
        return next_scene('Your_death')
        #return 'Death' 
    elif action == "hi chip":
        print "What's up loser?!?! Let's go to O&A..."
        return next_scene('Chip_in_studio')
    else:
        print "what's wrong with you? Let's go to my mother's house, I think Lamar's there..."
        return 'Chip_mom_house'

Most efficient conditional statement for multiple options?

it should still fix some issue This really depends on your actual logic. And I'm afraid this question might become flagged as it may be "too generic."
Still, there's a ton of ways to approach checking multiple states.
code :
switch(PolicyType){
    case "PersonalPolicy":
        // Code specific to PersonalPolicy
        break; // Don't forget to break unless you want to use "fallthrough logic"
    case "FarmOwnersPolicy":
       // Code specific to PersonalPolicy
       break ;
    case default:
       // Code for "any-other-than" cases :)
       break;
}
if ( PersonalPolicy ) { }
else { }

if (FarmOwnersPolicy && !SelectomaticPolicy ) {
    //Will only be executed if FarmOwnersPolicy is True AND SelectomaticPolicy is NOT true.
}

if (!FarmOwnersPolicy && !SelectomaticPolicy) {
    // Will only be executed if FarmOwnersPolicy AND SelectomaticPolicy are both unset
}

if (!FarmOwnersPolicy || !SelectomaticPolicy) {
    // Will  be executed if either FarmOwnersPolicy OR SelectomaticPolicy is unset
}
TestCase ? Value1 : Value2;
If (TestCase ){
    return Value1;
}
Else {
    return Value2;
}

Laravel Conditional Statement: is when() efficient?

will be helpful for those in need TL;DR: The when function is little more than syntactic sugar. It's not more efficient than regular conditionals, and (probably) not less efficient enough to worry about.
code :
public function when($value, $callback)
{
    $builder = $this;

    if ($value) {
        $builder = call_user_func($callback, $builder);
    }

    return $builder;
}
$q = $q
    ->when(isset($foo), function() use ($foo) { return $q->where('foo', $foo); })
    ->when(isset($bar), function() use ($bar) { return $q->where('bar', $bar); })
    ->when(isset($baz), function() use ($baz) { return $q->where('baz', $baz); });
if (isset($foo)) {
    $q = $q->where('foo', $foo);
}

if (isset($bar)) {
    // ...

Is using a conditional statement based on this flag more efficient than adding more lines of code?

it fixes the issue For code clarity, it will be better to make that a non-member function template and pass it a compare functor. Make sure to put the function in your application's namespace so there is no confusion with the functions of the same name from the std namespace.
Assuming Array::A is accessible,
code :
namespace MyApp
{
   template <typename T, typename Compare = std::less<T>>
   void sort(Array<T>& array, algo a, Compare compare = Compare());
   {
      if (a == algo::BUBBLE)
      {
         bool wasSwapped = true;
         for (size_t i = 0; i < size - 1 && wasSwapped; i++)
         {
            switched = false;
            for (size_t j = 0; j < size - i - 1; j++)
            {
               if (!compare(array.A[j], array.A[j + 1]))
               {
                  wasSwapped = true;
                  swap(array.A[j], array.A[j + 1]);
               }
            }
         }
      }
   }
}
Array<int> a = { ... };
MyApp::sort(a, algo::BUBBLE);                      // std::less<int> is the default functor.
MyApp::sort(a, algo::BUBBLE, std::greater<int>()); // Explicit compare functor.
