 Posted: Sat Oct 22, 2005 12:20 pm Post subject: Flatfile-database |
 |
|
I've been working on a small website, that uses one flatfile-database.
I use this script to make PHP read the db.txt-file:
| Code: | $open = fopen("db.txt", "r");
$file=fgets($open,1024);
fclose($open);
if ($file == ""){
echo "<b>Error.</b><hr>";
} else {
echo $file;
} |
This script will only output the first line of the database. How do I make it output everything in the database? |

| Code: | /* Probably don't need the explode. Can't be arsed to put it into theory. */
foreach(explode("\n", implode("", file("db.txt"))) as $this_key => $this_value) {
echo $this_value;
} |
Or something, probably. Don't use file wrappers all that much, MySQL 4 lyfe.

This will loop through the entire db.txt file and output the results. If the
file is empty , I could guess that you want an Error to be printed. LateR!
Note: This will also go to Error , if db.txt does not exist.
| Code: |
<?php
if (@filesize("db.txt") != 0) {
$open = fopen("db.txt", "r");
while (!feof($open)) {
$file = fgets($open, 1024);
echo $file;
}
fclose($open);
}else{
echo "<b>Error.</b><hr>";
}
?>
|
Note: If you have a huge file , the file() function would open that entire
file all at once and can slow down performance , this code uses a buffer.

the file() function reads the file into an array
| Code: | $open = fopen("db.txt", "r");
$fileArray=file($open);
fclose($open);
if(! is_array($fileArray) ){
echo "<b>Error.</b><hr>";
}else{
foreach( $fileArray as $val )
print "<br />$val";
} |

I edited my last post to show you why the file() function can be a bad
option to use. Reading a file into chunks can give better performance.

Kinda what I did, but you don't need to use fopen etc, you can just file().
TRUSTpunk -> I'd speculate that it probably isn't, but if it is I doubt it would be that much of a difference.

Correct me if I'm wrong, but this should read the file and output it exactly as it is, right?
| Code: |
$n = file_get_contents("file.txt");
echo $n;
