Here's something I did in a hurry. It can be greatly improved, but it
appears to work. The class is called IniReader. I put it into an include
file called inireader.inc.php, so that's why the example shows that as an
include line. The constructor takes 3 parameters - the file name, the
section heading, and the variable desired. See the example which returns
"United States".
First the example code (real short):
=================================
<?php
include('inireader.inc.php');
$ini = new IniReader('c:\windows\win.ini', '[intl]', 'scountry');
$ini->findvalue();
if ($ini->errorval == 0)
{
if (empty($ini->requiredvalue))
print("Not found or blank.<BR>");
else
print($ini->requiredvalue."<BR>");
}
else
print("Error #".$ini->errorval." encountered.<BR>");
?>
=================================
Now the class itself - (bigger, but not huge): it should be improved with
better error handling, but as a first pass.... what the heck:
Read it carefully, because word-wrap (yours or mine or both) is probably
going to mess it up pretty good.
=================================
<?php
class IniReader
{
var $filename;
var $sectionkey;
var $varkey;
var $errorval;
var $linearray;
var $requiredvalue;
// constructor takes name of ini file (with path) - ie
"c:\windows\win.ini",
// section - ie "[intl]",
// variable to resolve - ie "sCountry"
// with above, on my system, should return "United States"
function IniReader($filename = "", $sectionkey = "", $varkey = "")
{
$this->filename = $filename;
$this->sectionkey = $sectionkey;
$this->varkey = $varkey;
$this->errorval = 0;
$this->requiredvalue = "";
$this->linearray = array("");
}
// function to pull ini file into an array
function getfilearray()
{
if (empty($this->filename))
$this->errorval = 1; // no filename provided
elseif (!is_file($this->filename))
$this->errorval = 2; // no such file (or invalid
filename)
else
$this->linearray = file($this->filename);
}
function findvalue()
{
$this->getfilearray(); // load up array with ini file
if ($this->errorval == 0) // seems ok
{
if (empty($this->sectionkey))
$this->errorval = 3; // no sectionkey
provided
else
{
$eleval = current($this->linearray); // get
1st line of file
(array element 0)
// watch for end of file and look for sectionkey
requested
while (!($eleval === false) and
(strncasecmp($eleval,
$this->sectionkey,
strlen($this->sectionkey)) != 0))
$eleval = next($this->linearray);
// not found, so continue
$eleval = next($this->linearray); //
move to next line (could be
eof)
// watch for eof and only go until next section header
encountered
// if next section header found, then requested
variable value not
in this section,
// so don't bother continuing
while (!($eleval === false) and
(strcmp(substr($eleval, 0, 1), "[")
!= 0))
{
// did we find the variable desired?
if (strncasecmp($eleval, $this->varkey,
strlen($this->varkey)) ==
0)
{
// yes, so put it into
this->requiredvalue and quit looking
$tmpval = stristr($eleval, "=");
if (!($tmpval === false)) // no
value at all??? ok, possible
$this->requiredvalue =
trim(substr($tmpval, 1, strlen($tmpval)
- 1));
break;
}
else // not found yet so continue
$eleval = next($this->linearray);
}
}
}
}
}
?>
