Hello all,

I've made a little code to pull the line that starts with $reviewID all the way to the delimiter using stream_get_line. Here's the code:

PHP Code:

$reviewID = $_GET["reviewID"]; //Set the variable 'reviewID' as from the URL.

$transback = array(
"\n" => "<br />", //IMPORTANT, DO NOT CHANGE!
); //Simply changes all line breaks in the text file to <br/>s



echo "<br /><br />";  //Nice spacing
//////////////////////////
$database = fopen("ffdatabase.txt", "r");  //Opens the database into a variable called '$database'.
$start = strstr($database, $reviewID);; //Find the reviewID in $database
$end = strstr($database, "|");; //For later use, this makes the | the delimiter for $database
//////////////////////////

$MaxLenTotal = $MaxLenTitle + $MaxLenAuthor + $maxLenReview + $maxLenReason + 177; //Makes the pull length, not really important.

/////////////////THE PROBLEM!/////////////////////
//$line1 = stream_get_line( $database, $MaxLenTotal  [$end] );  //sets $line1 as: get $database, pull $MaxLenTotal characters from it, and end at $end.
$line1 = stream_get_line($database, $MaxLenTotal, "|");  //sets $line1 as: get $database, pull $MaxLenTotal characters from it, and end at |.

$line2 = strtr("$line1", $transback); //Uses the $transback function above

echo "$line2"; //Echoes the finished product to the page 


As you can see, I have a funciton where it takes the value in the URL, and looks for it in the database. Then it just formats it ($transback) and echoes to the page.

The problem is; I can't get it to look for the value in the URL.

If I comment the first one (so the second one works), I get just the first section up to the delimiter. If I comment the second one (so the first one works), it shows the entire database.

Can somebody please just fix the code above (not write a whole new one) and make it so itt works the way I want above?

Thanks very much!

Are you not getting any errors or warnings? When you open a file with fopen() you get kind of a "link" (called resource at php.net) to the file, and you can't use strstr() on it. strstr() expects a string. You need to first read the content into one big string, then you could split the content at | into an array. Then go thru the array to find the one that starts with $reviewID.

PHP Code:

$filename = "ffdatabase.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);

$entries = explode('|', $content);

$myEntry = null;
foreach ($entries as $entry) {
   $entry = trim($entry); // remove possible spaces in beginning and end
   if (substr($entry, 0, strpos($content, ' ')) == $reviewID) {
      $myEntry = $entry;
      break;
   }
}

if ($myEntry == null) {
   // Couldn't find the entry
} else {
   // Do something with $myEntry
} 


My example is based on that your file have this structure.

1 This is the first entry | 2 This is the seccond entry | 3 This is the third entry

or

1 This is the first entry |
2 This is the seccond entry |
3 This is the third entry

Oh, and one more thing. There is a function built in to php for replacing line brakes with <br />, nl2br().

Yes, I know. I would prefer not to use nl2br because with what I'm using, you can add more translations.

And thanks for the code! My database is structured like this:

Mm62r - CONTENT
CONTENT
CONTENT
CONTENT
CONTENT CONTENT
CONTENT |

874yh - CONTENT...
..CONTENT |

But I can tweak it to work for me, thanks!

EDIT

Uhh, your code doesn't seem to be working... I have it to echo $myEntry if found, and everything is right, anyway here's my code:

PHP Code:


$reviewID = $_GET["reviewID"]; //Set the variable 'reviewID' as from the URL.

$transback = array(
"\n" => "<br />", //IMPORTANT, DO NOT CHANGE!
); //Simply changes all line breaks in the text file to <br/>s



echo "<br /><br />";
$filename = "ffdatabase.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);

$entries = explode('|', $content);

$myEntry = null;
foreach ($entries as $entry) {
   $entry = trim($entry); // remove possible spaces in beginning and end
   if (substr($entry, 0, strpos($content, ' ')) == $reviewID) {
      $myEntry = $entry;
      break;
   }
}

if ($myEntry == null) {
   echo "Couldn't find your entry";
} else {
   echo "$myEntry";
} 


I don't see anything wrong with that...

Sorry, seems I missed a 's' in $contents, at this line

PHP Code:

$entries = explode('|', $contents); 


Also, if you want to replace line brakes your way, you should at least do it properly :P
The strstr() function is used to find a string inside another string, it won't replace anything.

PHP Code:

$find    = array('find1', 'find2', 'find3');
$replace = array('replace1', 'replace2', 'replace3');

$myEntry = str_replace($find, $replace, $myEntry); 


Also, perhaps you know this already but still, for printing out variables there is no need to encase them in quotes.

PHP Code:

echo $myEntry;
//will work just as fine as

echo "$myEntry";

// and is probably by most poeple concidered "better". In performance I
// bet there is no difference, but it seems strange to make string out of
// everything before printing them out. Plus, in this case $myEntry is
// already a string.

// However, single quotes won't work the same way.

$var = "Hello World!";

echo $var;   // will print 'Hello World!'
echo "$var"; // will print 'Hello World!'
echo '$var'; // will print '$var' 


Thanks for that! It works now, but I want it so when the URL is something like userreview.php?reviewID=MmPf3, look for the line that starts with MmPf3 and stream_get_line up to the delimiter. I've gotten some progress, but it doesn't work quite yet, so I won't post it.

Thanks for your help so far though, and fantastic replies!

Ok I'll post it anyway.

PHP Code:


$reviewID = $_GET["reviewID"]; //Set the variable 'reviewID' as from the URL.

$transback = array(
"\n" => "<br />", //IMPORTANT, DO NOT CHANGE!
); //Simply changes all line breaks in the text file to <br/>s

$database = fopen("ffdatabase.txt", "r");
$database2 = file_get_contents('ffdatabase.txt');
$datatrans = strtr("$database", $transback); //
//echo $datatrans;

$datasplit = strstr($datatrans, $reviewID);
$datadelim = stream_get_line($database, $MaxLenTotal, "|");
echo "ReviewID $datadelim"; 


For some reason, that won't work... It just displays the first 'review'...

I don't know what you're trying to do in that piece of code, that's just messy :O
The code I posted, together with the fixes, should work fine. And now you're opening the file, then use file_get_contents(), and still try to replace stuff with strstr()... And I don't see why you want to use stream_get_line() either.

Try to make a new page and copy/pase all my code, with the fixes, and see if it works. Then work your way from there. You can use file_get_contents() if you wish. Basically this code

PHP Code:

$filename = "ffdatabase.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle); 


can be replaced with this

PHP Code:

$contents = file_get_contents("ffdatabase.txt");
