[RESOLVED] -> = and some other questions

What does => do, and whats the difference from that an =?

Also, how come i cant just do:
$response-> getit();

but i have to do
$stuff = $response-> getit();

or else it $stuff will just return 'object'?

Thanks :wave:

edit*

How do i find the ascii of a string char?

I have no idea what you are talking about :confused:

-> is the object access operator and
=> is used to assign key names to arrays

Okay, I have some source and it uses an include file where there are functions..i cant just use the functions like normal, i have to use => and i dont know why..

Also how do i find the ascii of a letter?

Do you mean -> ?? You never access functions using =>

Like I said in my previous post, -> is the object access operator. Its the equivilent of a . in VB and is used to access object members.

VB Code:

Dim myObj As new MyObject
 
Print myObject.property;
Print myObject.memberFunction;

The same in PHP would be:

PHP Code:

---

$myObj = new MyObj;

echo($myObj->property);
echo($myObj->memberFunction()); 


---

ord() should be what you're looking for.

visual yeah your right, -> is what im using. I now understand what the thing does, and thanks yak for the ord thing.

Also one more question:
Is there a mod operator? Something that will tell me if one number is divisible by another?

found it bcmod

okay, lemme see if i got this right, to see if a number is divisble by like 4 you do

PHP Code:

---

if (bcmod('8','4') == '0'){ 


---

am i right?

The modulus operator is the percent sign:
'%'

Good luck;
