Output Line in File

[verdrm]

I have a text file and I need to find a specific line and output the contents of the line.

 

Example (in file):

CurrentVersion = 1.2.3.4 

 

I need to get the "1.2.3.4" after CurrentVersion. How can I do that?

 

Thanks!

The structure is like an ini file. Try to parse your file with http://php.net/manual/en/function.parse-ini-file.php

[verdrm]

Thanks. It isn't an INI file though. How would I do this regardless of the file extension?

Theres a lot of choiches. Two of them:

 

http://php.net/manual/en/function.file-get-contents.php

http://php.net/manual/en/function.file-get-contents.php

 

and google!!!: http://www.google.hu/search?sourceid=chrome&ie=UTF-8&q=php+file+read

Could you provide a code example for finding the line and outputting it?

[kenrbnsn]

The parse_ini_file function doesn't care what the file extension is.

 

Let's say I have a file named "x.x" which contains:

line1
line 2
line 3
CurrentVersion = 1.2.3.4

Using

<?php
$x = parse_ini_file('x.x');
?>

$x contains

Array
(
    [CurrentVersion] => 1.2.3.4
)

I tried that against my INF file using the code you provided.

 

When I used a file with test data:

 

[Config]

one = two

 

I could output "two" using $e[one];

 

However, in the actual file I am using, this does not work.

 

[Version]

signature  = "$Windows NT$"

Class      = "ActivityMonitor"

ClassGuid  = {b86dff51-a31e-4bac-b3cf-e8cfe75c9fc2}

Provider    = %Symc%

DriverVer  = 06/24/2009,12.8.0.10

CatalogFile = SymEvent.cat

You're getting errors because there are strings containing non alphanumeric characters that are not quoted. If you change your file to contain:

[Version]
signature   = "$Windows NT$"
Class       = "ActivityMonitor"
ClassGuid   = "{b86dff51-a31e-4bac-b3cf-e8cfe75c9fc2}"
Provider    = "%Symc%"
DriverVer   = "06/24/2009,12.8.0.10"
CatalogFile = SymEvent.cat

then the function will work.

The file is that way on many machines, and can't be changed manually. How else can I do this without using parse_ini_file()?

 

I just need a code example for using fread to find the line and display it.

[PFMaBiSmAd]

I used parse_ini_file() on the data you posted and got the expected results -

            [signature] => $Windows NT$
            [Class] => ActivityMonitor
            [ClassGuid] => {b86dff51-a31e-4bac-b3cf-e8cfe75c9fc2}
            [Provider] => %Symc%
            [DriverVer] => 06/24/2009,12.8.0.10
            [CatalogFile] => SymEvent.cat

 

Perhaps if you defined: this does not work?

 

[verdrm]

Can you post the exact code you used?

 

[Pikachu2000]

I think you want just the contents of the one specific line, right? Easy enough to do; just foreach() loop through the result of parse_ini_file (which is $x) and echo the $key and $value where the $key == your_string.

[verdrm]

The problem is that I can't get the results to print out.

 

Code:

 

$x = parse_ini_file('file.inf');

print_r($x);

 

This doesn't work.

 

My Data:

 

[Version]

signature  = "$Windows NT$"

Class      = "ActivityMonitor"

ClassGuid  = {b86dff51-a31e-4bac-b3cf-e8cfe75c9fc2}

Provider    = %Symc%

DriverVer  = 06/24/2009,12.8.0.10

CatalogFile = SymEvent.cat

[PFMaBiSmAd]

My code -

<?php
$x = parse_ini_file('config.inf');
echo "<pre>",print_r($x,true),"</pre>";
?>

 

Are you sure the file is named like you are using in the code and it is not actually - file.inf.txt? Are you developing and debugging your php code on a system with error_reporting set to E_ALL and display_errors set to ON so that all the errors php detects would be reported and displayed?

[verdrm]

Yes, I checked all of those things you mentioned.

 

 

Is it the illegal characters in the file? I can't remove them.

[verdrm]

I'm getting this error using your snippet of code:

 

Warning: parse error, expecting `TC_DOLLAR_CURLY' or `TC_QUOTED_STRING' or `'\"''

[PFMaBiSmAd]

I copy/pasted your exact posted values. Best guess is this is an actual Windows generated .inf file and it contains some non-printing characters.

[kenrbnsn]

This is interesting, when I use xampp (Windows 7, php 5.3.1), it works perfectly. When I use the PHP CLI on my Linux box (php v5.2.9), I get a error parsing the file. When I move the script & file that work under php 5.3.1 to the linux box and run it I get the error:

Warning: Error parsing config.inf on line 4 in /home/rbnsn/public_html/phpfreaks/test_ini.php on line 2

the file contains

[Version]
signature   = "$Windows NT$"
Class       = "ActivityMonitor"
ClassGuid   = {b86dff51-a31e-4bac-b3cf-e8cfe75c9fc2}
Provider    = %Symc%
DriverVer   = 06/24/2009,12.8.0.10
CatalogFile = SymEvent.cat

I managed to get it to work using code on the PHP manual page for the ini parser.

 

Array ( [Version] => Array ( [signature] => $Windows NT$ [Class] => ActivityMonitor [ClassGuid] => {b86dff51-a31e-4bac-b3cf-e8cfe75c9fc2} [Provider] => %Symc% [DriverVer] => 06/24/2009,12.8.0.10 [CatalogFile] => SymEvent.cat )

 

 

The only issue now is how do I extract DriverVer?

[kenrbnsn]

Assuming the output of the function is stored in $out, you would do

<?php
echo $out['Version']['DriverVer'];
?>

Does the file exist in the same directory as the script?

[verdrm]

Thanks. Problem solved.
