[Snippet] File Write/Read

xhtmlphp said:

File write; if file does not exist it will attempt to create it, also it will write to the end of the file

Code:

$data = 'Some text';
$filename = 'file.html';
$open = fopen($filename, "x+");
fwrite($open, $data);
fclose($open);

File write; if file does not exist it will attempt to create it, also it will write to the beginning of the file. Meaning that it will clear all the text within the document and replace it.

Code:

$data = 'Some text';
$filename = 'file.txt';
$open = fopen($filename, "w+");
fwrite($open, $data);
fclose($open);

File read; the contents of the file will be saved under the '$contents' variable.

Code:

$filename = 'file.txt';
$open = fopen($filename, "rb");
$contents = fread($open, filesize($filename));
fclose($open);

$data = 'Some text';
$filename = 'file.html';
$open = fopen($filename, "x+"); // a just appends. x+ creates .
fwrite($open, $data);
fclose($open);

$filename = 'file.txt';
$open = fopen($filename, "a+");
$contents = rename($filename, newfilename.txt);
fclose($open);

correcting you

btw you can just use ... file_exists()

PHP:

$data = 'Some text';
$filename = 'file.html';
$open = fopen($filename, "x+"); // a just appends. x+ creates .
fwrite($open, $data);
fclose($open);

rename("images","pictures");


this is TOTALLY wrong.

PHP:

$filename = 'file.txt';
$open = fopen($filename, "a+");
$contents = rename($filename, newfilename.txt);
fclose($open);

Where did you get "rb" from?

I'm not criticizing you, just helping.

Ages ago I read a snippet using 'rb' and have used it ever since for reading a file; I didn't just copy/paste it every time though

rename($name, $newname);
