|Here is a tip for displaying HTML inside your php . This is specially useful when you are using ‘if’ statements or anything that uses a block and when you need to do this on a condition or you need to output a lot of HTML inside something that is working on php.

|In this example, I’ve got a variable- Name, and this is set  to Alex.

|so if i type-  name equals Alex, then, it will echo out “Hi, Alex”

|If name is not equal to Alex-so we type ‘else’- we will echo out “You are not Alex.  Please type your name”.

|And we have an input field here which should have a form around it.   

|So, “Form action equals Index.php”

Method =post    

And we end the form  here.

|We can bring this down a bit, so that it looks better. So, we have  some HTML codes inside this Else block .   

|So we type ‘If else’ and we have got a block starting here,  and a block ending here.  And what could be a lot of HTML code.

|The purpose of this tutorial is to show you that you don’t need to use Echo and echo out HTML code.   

|It’s easier and saves time when you want to code using quotation marks rather than single inverted commas..

|Also it’s nicer to have a code inside the blocks ,say, this block here without having to worry about what you are typing.  

|So, if you are used to quotation marks this forward slash will escape the character.   

|So, it will be displayed but will be ignored  as the end of the Echo and the beginning of this Echo here.

|For example.  Let’s just refresh.

|Since name equals Alex it is greeting me as we saw earlier.

|The Echo is okay for a small amount of text but for a large amount with a form etc,  we don’t want the echo.

|As it stands at present , it won't run. We will receive an error . We haven't provided a method of output for this text.

|We have our  php opening tag here. And I am going to end the tag down here .

|So, we are ending the tag after the block starts. Now I will start a new tag just before the flower brackets or curly bracket here.

|So now we have a chunk of php code here and a chunk here.  And the rest here is not interpreted as php.  Since it is HTML it will be displaced as HTML code.

|So, what I am going to do first is change all these to quotation marks.   

|If you implement this method from the beginning , you could code easily and it would work a lot better.

|So once again as is visible on the screen we have a block here and the block here.  It may appear as though the php would end here .

|But we have not ended a block inside here, in this area , but we are going down here. We aren’t echoing out but displaying this.   

|This applies specifically to the Else block. We end the block in the blue highlighted line here and here .

|So again we will first get “Hi, Alex”. Now if we change the name to Let’s say Kyle, refresh.

|You will see that the HTML has been displayed properly.  But it hasn’t been echoed out using php.

|This is a good method to use when you want to display HTML properly and re- read easily.  Hope this tutorial has been helpful .Thank you for watching.
