Searching a file for string

[XeroXer]

Hi there!
I have a textfile containing different information strings.
The content is listed like this:
[code]abcd:dcba:1234
4321:efgh:hgfe
5678:ijkl:mnop
ponm:8765:lkji[/code]
... Well you get the point.
I want to be able to search with a php script in this file.
The row/rows containing the search string should be listed by the script.
So if I would have searched in the above file for [color=red]5678[/color] I would get this result listed:
[code]5678:ijkl:mnop[/code]
But as I wrote is must be able to handle multiple rows containing the string.

I also want so that the different parts of the search string should be divided by some colorcode.
Like this:
[color=red]5678[/color]:[color=blue]ijkl[/color]:[color=green]mnop[/color]

Can anyone do this or help me with the commands to do it myself?

I guess that's not the fastest way, but it'll do :)

[code]<?php
//$text holds the value of the text file as a string (IE using file_get_contents() or anything simillar)

$regex = "/([a-z0-9]+):(5678):([a-z0-9]+)|(5678):([a-z0-9]+):([a-z0-9]+)|([a-z0-9]+):([a-z0-9]+):(5678)/is";

preg_match_all($regex,$text,$matches);

foreach($matches[0] as $row)
{
$temp = explode(":",$row);
echo "First = ".$temp[0]."<br>Second = ".$temp[1]."<br>Third = ".$temp[2]."<br><hr><br>";
}

?>[/code]

Orio.

I can't get that to work.
I did like this:
[code]<?php
$text = file_get_contents('file.txt');
$regex = "/([a-z0-9]+):(5678):([a-z0-9]+)|(5678):([a-z0-9]+):([a-z0-9]+)|([a-z0-9]+):([a-z0-9]+):(5678)/is";
preg_match_all($regex,$text,$matches);
foreach($matches[0] as $row)
{
$temp = explode(":",$row);
echo "First = ".$temp[0]."<br>Second = ".$temp[1]."<br>Third = ".$temp[2]."<br><hr><br>";
}
?>[/code]
and it prints out nothing...

[Orio]

Works fine for me.... Are you sure file.txt exists and $text receives the data all right?
(Add after "$text = file_get...." the line "echo $text" and see if there's any output)

Orio.

[XeroXer]

If I type echo $text I get all the file content printed out yes.

Is there any limitations regarding what letters, numbers och signs that can be used in the file?
Because now the first part consists of just letters (small and large) and number.
The second and third part is just about any sign you can get into a filename.
For example: []()$-_

Yes, I assummed all the charaters are alphanumeric. Here is another version that can match all characters (but I added a limition of 4 charaters for each one, I hope that's how the file looks like too- at least it seemed so from the example):

[code]<?php

$text = file_get_contents('file.txt');

$regex = "/(.{4}):(5678):(.{4})|(5678):(.{4}):(.{4})|(.{4}):(.{4}):(5678)/is";
preg_match_all($regex,$text,$matches);
foreach($matches[0] as $row)
{
$temp = explode(":",$row);
echo "First = ".$temp[0]."<br>Second = ".$temp[1]."<br>Third = ".$temp[2]."<br><hr><br>";
}
?>[/code]

Orio.

[XeroXer]

Actually no. :)
The lenght differs from row to row.
I think the longest infostring so faar is 55 characters.  ::)

[Orio]

lol
Let's try now, I think this will work this time after you confusing me  :P

[code]$regex = "/\n(.*?):(5678):(.*?)\n|(5678):\n(.*?):(.*?)\n|\n(.*?):(.*?):(5678)\n/is";[/code]

Orio.

[XeroXer]

this is driving me crazy.
my code now looks like this:
[code]<?php
$text = file_get_contents('file.txt');
$regex = "/\n(.*?):(5678):(.*?)\n|(5678):\n(.*?):(.*?)\n|\n(.*?):(.*?):(5678)\n/is";
preg_match_all($regex,$text,$matches);
foreach($matches[0] as $row)
{
$temp = explode(":",$row);
echo "First = ".$temp[0]."<br>Second = ".$temp[1]."<br>Third = ".$temp[2]."<br><hr><br>";
}
?>[/code]
And I get no result.

I also noticed that when I echo the code it doesn't show the rowchanges I have in my .txt file.
It just prints it all out with automatic rowchange here and there...

[Orio]

Dont worry about that, you can use the nl2br() function if you want to show it nicely.
I now understand the problem :) I had one of the "\n" out of place :)
[code]$regex = "/\n(.*?):(5678):(.*?)\n|\n(5678):(.*?):(.*?)\n|\n(.*?):(.*?):(5678)\n/is";[/code]

Orio.

[XeroXer]

I want to smash my computer to bits.
Still won't work........

[XeroXer]

Who won't this output anything?
[code]
<?php
$text = file_get_contents('file.txt');
$text = nl2br($text);
$regex = "/\n(.*?):(c944):(.*?)\n|\n(c944):(.*?):(.*?)\n|\n(.*?):(.*?):(c944)\n/is";
preg_match_all($regex,$text,$matches);
foreach($matches[0] as $row)
{
$temp = explode(":",$row);
echo "First = ".$temp[0]."<br>Second = ".$temp[1]."<br>Third = ".$temp[2]."<br><hr><br>";
}
?>
[/code]

Try increasing your error reporting and see if there were errors. At the start of the script add:
error_reporting(E_ALL);

Orio.

PS
gtg now, sorry about the fact we havent solved your problem yet, altough I think we made progress :)

[XeroXer]

Added that row and still I get nothing printed out.

Is there any character that would destroy this script?
Make it not being able to search?

PS
If you have time tomorrow I would appreciate it if you would help me then. :-)

[Orio]

This is weird, can you send me the file or something (or upload it in here).

Orio.

[Zane]

might work...no guarentees but worth a try
[code]
<?php
$lines = file('file.txt');

$searchFor = '5678';
$results = array();

foreach($lines as $line) {
if(ereg($searchFor, $line);
$cols = explode(":", $line);
$color = array('red','greed','blue');
for($x=0;$x<count($cols);$x++) {
$cols[$x] = printf("<font color='%s'>{$cols[$x]}</p>", $color);
}
$line = implode(":", $cols);
$results[] = $line;
}

print_r($results, true);
?>
[/code]

[XeroXer]

I can give you an example of the rows...
[code]b1ed9d52b23577a036c9591cdac0194a:counter-strike(v.3).gif:[C]ounter-[S]trike game loader version 1$2. (gif)[/code]

zanus:
[code]Parse error: syntax error, unexpected ';' in /customers/xeroxer.com/xeroxer.com/httpd.www/_/-/search/test.php on line 8[/code]

[Orio]

Remove the ; from:
if(ereg($searchFor, $line);

Orio.

Then I get:

line 9 being:
[code]$cols = explode(":", $line);[/code]

[Orio]

Using zanus's code, bugs fixed:

[code]<?php
$lines = file('file.txt');

$searchFor = '5678';
$results = array();
$color = array('red','greed','blue');

foreach($lines as $line)
{
if(ereg($searchFor, $line)
{
$cols = explode(":", $line);
for($x=0;$x<count($cols);$x++)
$cols[$x] = sprintf("<font color='%s'>{$cols[$x]}</p>", $color[$x]);
$line = implode(":", $cols);
$results[] = $line;
}
}

print_r($results, true);
?>[/code]

Orio.

[code]Parse error: syntax error, unexpected '{' in /customers/xeroxer.com/xeroxer.com/httpd.www/_/-/search/test.php on line 11[/code]

[Zane]

there's a missing ' ) '...here

[quote]if(ereg($searchFor, $line)[b])[/b][/quote]

[XeroXer]

Changed that now.
Get no error but still no output from the file.
