|-
|0:00
|Right now I am onto the last two common errors that I have included.
|-
|0:05
|And we will start with the hard one.
|-
|0:09
|This is php header and we are using "header" function going to a location.
|-
|0:14
|And here I have got some html code.
|-
|0:18
|This is a header tag, I am saying "Welcome!".
|-
|0:21
|And our "goto" variable is "google dot com".
|-
|0:26
|If the "goto" exists, which it currently does, we are going to redirect the page to a u-r-l "google dot com".
|-
|0:35
|Right now, this will return an error.
|-
|0:37
|And the error is - Oh! um... Okay that’s why. "o b start".
|-
|0:50
|Lets get rid of this. That wasn’t supposed to be there. That code is to fix the error!
|-
|0:56
|Sorry, so we will go to "php header" and we have got "Welcome!" - our html code.
|-
|1:03
|Then a warning - "Cannot modify header information – headers already sent by..." and all of this.
|-
|1:10
|Okay so our headers have already been sent. This is the line no. by the way.
|-
|1:16
|1, 2, 3 so if it gives you an error like "phpheader dot php" colon 3, then the error has occurred on the line no. 3.
|-
|1:26
|So that's where the error is - on line 3, okay?
|-
|1:32
|And this error has been generated by line 9, which if you go here, is our "header" function.
|-
|1:39
|So the reason that this is happening is we are already sending our html code.
|-
|1:47
|If I get rid of this by commenting it, and I were to refresh then we would be redirected to google.
|-
|1:54
|But the point is that we want this welcome header here.
|-
|1:59
|And you can’t actually put html before a header function, going to location and other features of this function.
|-
|2:10
|You shouldn't do so.
|-
|2:15
|So as you saw a minute ago that is "ob underscore start".
|-
|2:20
|What this does is, it fixes this problem for us.
|-
|2:25
|So I can come here to "phpheader" and it works, even though I have still got my html code echoed here before my header.
|-
|2:37
|So without this we get an error (pause) and with this our header works fine, okay?
|-
|2:47
|Despite the initial rule of no html output before header up here.
|-
|2:53
|That should be pretty clear by now.
|-
|2:55
|Now, the last one is extremely simple.
|-
|2:58
|I don’t even need to explain it but anyway.
|-
|3:02
|This is "include a file which doesn’t even exist" named as "idontexist dot php".
|-
|3:08
|So lets have a look. Um.. where is it? "missing dot php".
|-
|3:13
|Oh no! Its not. "open dot php".
|-
|3:16
|Okay! So - include "idontexist dot php" failed to open stream; no such file or directory in that name here.
|-
|3:25
|Our file name and directory on line 3.
|-
|3:27
|So lets come to line 3.
|-
|3:30
|And that is the only line of significant code in this file.
|-
|3:35
|We have another warning here - Failed to open "idontexist dot php" for inclusion and all of this. So we get two errors.
|-
|3:43
|This is quite messy when you have a page that has "include a header file".
|-
|3:50
|Then these don’t look too nice. I mean you have probably been in a website before and you have seen this at the top.
|-
|3:57
|You need to be attractive. So you can put a "@ (at)" symbol in front and refresh.
|-
|4:02
|That won't show the error anymore.
|-
|4:06
|But it doesn’t excuse the fact that the file doesn’t exist.
|-
|4:10
|So the content of the file which doesn’t exist, won’t be included.
|-
|4:14
|But yes, to be honest, looking at this, this is really pretty much self explanatory. I just thought I should explain this anyways.
|-
|4:23
|So we have got a small collection of errors that you might come across when you are programming in php.
|-
|4:30
|If there are other errors that you are getting, then please message me and I will be happy to help.
