Php Keys (Lecture -8)

hey guys what's going on is clever taking and then this lecture we're going to

we Interpol nation what is inter palatial well it's a way to accessories

and they methods and properties inside double quilt so I broke them down in

for categories first as a preferred way then there are valid alternatives then

there's the only way and finally, there we're are only in valid ways to

access properties etc so let's go over the preferred method first so if you

haven't made with a single so she ate off a key and there are no spaces in that

the associated key you must think to close the whole thing in early brackets now

next, if you have just in numeric or a with a new very key then you don't

need any early back it's for that and that only applied to a single a single

dimensionally erase now this is a really cool one here you have an object

and he too acts as a property name you don't need any curly back and this is

the one that I'd just found out about as I was making this Lecture I thought

that you had two enclosed those literally dragons before and as it turns out

you don't have to so this is just I'm the really clean way of vaccine property

themes of your objects so next there's a valid alternative so this one i

also didn't know about so if you have associative things so dimensionally

china the associative clean name you actually don't have to inclose it in

the quotes in the single calls in this case and php man you know all that's

what they say you don't have to in close that in any quotes however you can

get a little messy later on if you try to print the south outside of double

codes(Dallas Website Development) it's not me we're also if you have a space in your associated key

that's also not going to work out so I still prefer the preferred method off

ink using the associate a key inside the early brackets inside the double

codes when you haven't single associative or a key so if you have a new

meraki you can also in close it in Kuril brackets but these early brackets

optional so I prefer this way here and also undervalued alternatives we have

our property names you can also egos him and early Braque is but they're

also optional as I've just found out so the third is the only way you can

the access he can access the properties and in this case, we're trying to

access object method and you can now access object method if seeing close it

in curly brackets however, that's not true for regular functions as you can

see down here I've at contaminated the function with the dogs with the

contaminate operators so when it comes to object methods you can in clothes

that and currently brackets but we need it when it comes to functions you

must compact undated and looked up we got an associated a single dimensional

with space which you must in closing currency brackets and for any

multidimensional erase just remember that we have to enclose all multi-touch

secondly inherently brackets whether there are numeric or associative so

[UM] names you must can cattle eight and cars and you've also most can

captain eight Constance you can just put them inside the box with currently

brackets or in any other way so invalid methods here you can see he said me

live printed the a with an associate keep the devil course which is

not going to work you're going to get an error he up next as a constant

enclosed in the current brackets which are not going to work as well next

as a function (Dalllas Website Development)name and clothes and thirdly brackets which is also I'm going

to work because you can see the text high lotteries interpret the values

as just strings next that we got an object property which is enclosed in

a single curly bracket that's invalid next we have a method called which is

not in clothes and early brackets, that's not going to as opposed to math

properties next so we got a multidimensional or a which is not a clothes

and cold brackets lesson are going to work and the next we got which is we

got which is a multidimensional rate there has a three key followed by then

niemira key which is a closed incurably brackets now that that is a tricky

one because you can use a single dimensionally without enclosed and the the

in single calls but one
