[SOLVED] Help needed, beginner here.

[Jpower24]

I need to create a php script to....

declare and assign 3 integer variables, one for house number one for zip code and one for the area code. Use echo() statements to print each variable along with gettype() to assure each variable is of data type integer.

 

 

I appreciate any help as I have almost no experience with php.

<?php
$house_addr = gettype(1234);
$zip = gettype(12345);
$area_code = gettype(123);
if($house_addr != "integer"){
# tell users wrong datatype
}else{
#run your house_addr code
}
if($zip != "integer"){
# tell users wrong datatype
}else{
#run your zip code
}if($area_code != "integer"){
# tell users wrong datatype
}else{
#run area_code code
}
?>

im having a bit of trouble with that, i run it and nothing comes up. I think im supposed to use the echo command as echo 'text here'.

If you use that code provided by The Little Guy then nothing will come up as you are not echo'ing anything. To make it echo something just add echo 'whatever' where the comments are in the if/else statements code blocks. A code block is defined in between  the curly braces { and }

I thought maybe # was short for echo.  So now that that is cleared up, it's just one last thing.

 

how could I make it echo the values back.

 

something like

 

 echo 'The address is $house_addr' 

[The Little Guy]

ues one of these:

 

echo 'The address is '.$house_addr;

 

or

 

echo "The address is $house_addr";

[wildteen88]

Use double quotes instead if you want to echo variables values in a string.

 

If you use single quotes PHP will treat variables as normal text (as-is).

 

So use

echo "The address is $house_addr";

instead or you can use concatenation (See The Little Guy's example above in his post)

alright so now I have this.

 

<?php
$house_addr = gettype(1234);
$zip = gettype(12345);
$area_code = gettype(123);
if($house_addr != "integer"){
echo "The number of the house is 

$house_addr";
}
if($zip != "integer")
{
echo "The zip code is $zip";
}
if($area_code != "integer"){
echo "The area code is $area_code";
}
?>

And whats wrong with it now/what are you trying to do with it now.

[Jpower24]

well I try and run it and get a blank screen. Theres a good chance, i don't know how to run it.

If looks like it will run to you guys though thats good enough for me.
