In this lesson you
will
learn how to create a file.
PHP
- Creating Confusion
In
PHP, a file is created using a command that is also used to open files.
This is a little confusing.
The
fopen
function is used to open files.
If fopen
does not find the file specified (does not exist),
it will create that file.
PHP - How to Create a File
The
fopen function needs two information to operate
correctly.
First, we must supply it with
the name of the file.
Secondly, we must tell the function what we plan on doing
with that file.
(i.e. read, write, append etc).
PHP Code:
$FileName
= "testFile.txt";
$FileHandle = fopen($FileName,
'w');
fclose($FileHandle);
The file "testFile.txt" should be created in the
same directory where this PHP code resides.
When
PHP saw that
"testFile.txt" does not exists and fopen created
that file.
Let's look closely at the codes.
$FileName
= "testFile.txt";
Here we create the name of our
file, "testFile.txt" and store it into a PHP String variable $FileName.
$FileHandle = fopen($FileName, 'w')?
This bit of code actually has two
parts. First we use the function fopen and give it
two arguments: (1) File name
and (2) We indicate that we want to
write by character "w".
Then, the fopen
function returns what is called a file handle.
It will allow us to manipulate the file and we save the file
handle
into the $FileHandle variable.
fclose($FileHandle);
We close the file that was opened. fclose
takes the file handle that is to be closed.
