[SOLVED] How to update an ini-like file?

[julia k]

Hi there! My first post here (the reason I joined your forum!) hehe

 

My problem is that I have set my application's settings in an ini file. I can get and write new values in it without problems only that I cannot update any existing settings

 

anyone can help me with this? please?

 

thank you in advance!

Pretty girls don't write code

 

Just kidding... you would probably need to post the file contents, and the script that adds to it so we can get some sort of an idea as to how to accomplish what you're asking.

Hi Matthew! haha! well...some do :)here is the function that I use to write new values in the file:

function write_ini($sSection='app_settings', $sKey, $sValue){    global $settings_file;    $sFileHandle = fopen($settings_file, "r");    if (!$sFileHandle) {        die("<b>Error:</b> Unable to open ".$settings_file.".");    }    if (filesize($settings_file) > 0) {        $sFileContents = fread($sFileHandle, filesize($settings_file));    }    if ($sFileContents === FALSE) {        die("<b>Error:</b> Unable to read data from ".$settings_file.".");    }    $sFileData = preg_split("/ ? /", $sFileContents);    $sectionStart = -1;    $sectionEnd = -1;    $returnLine = -1;    for ($i = 0; $i < count($sFileData); $i++)    {        $x = strpos($sFileData[$i], "[".$sSection."]");        $y = strpos($sFileData[$i], "[");        if ($y == 0 && $y !== FALSE && $sectionStart >= 0 && $sectionEnd == -1) {            $sectionEnd = ($i - 1);        }        $z = explode("=", $sFileData[$i]);        if (count($z) >= 2) {            if ($z[0] == $sKey && $sectionStart >= 0 && $sectionEnd == -1 && substr($sFileData[$i], 0, 1) != ";") {                $returnLine = $i;            }        }        if ($x == 0 && $x !== FALSE && $sectionStart == -1) {            $sectionStart = ($i + 1);        }    }    if ($sectionEnd == -1) {        $sectionEnd = (count($sFileData)-1);    }    $newfile = "";    if ($returnLine > -1) {        $sFileData[$returnLine] = $sKey."=".$sValue;        for ($i = 0; $i < count($sFileData); $i++) {            $newfile .= $sFileData[$i]." ";        }    }    else {        if ($sectionStart > -1) {            for ($i = 0; $i < count($sFileData); $i++)            {                if ($i == $sectionEnd) {                    $newfile .= $sKey."=".$sValue." ";                }                $newfile .= $sFileData[$i]." ";            }        }        else        {            for ($i = 0; $i < count($sFileData); $i++) {                $newfile .= $sFileData[$i]." ";            }            $newfile .= "[".$sSection."] ".$sKey."=".$sValue." ";        }    }    fclose($sFileHandle);    $sFileHandle = fopen($settings_file, "w");    if (!$sFileHandle) {        die("<b>Error:</b> Unable to open file ".$settings_file." with write access.");    }    $sFileWrite = fwrite($sFileHandle, trim($newfile));    if ($sFileWrite === FALSE) {        die("<b>Error:</b> Unable to write data to file ".$settings_file.".");    }}

to get the values, I use the

$ini = @parse_ini_file($settings_file/*[,true]*/);

where $ini would be an array, you know...For the ini file I use the same format as the one used in the php's ini file...

 

whoa! this editor is pretty messy

[julia k]

The point of all this is that I want to move all the content of my settings.php file into the ini file, so I'll need to update some keys when I change them from the admin section and I don't want to use a table just to have a single row in it.

Why not make the app read a serialized array stored in a file? Then to update it all you would simply unserialize it, change the keys you need, then serialize it, and put it back into the file.

hmmm, never thought of that... [i thought the ini file would be a good option.], but I will do nowthanks [/]

[julia k]

To be honest, I never used the serialize and unserialize functions 'til now. I've ran a simple test and, yes, this would be my chosen way thank you very much, aximbigfan.

see you guys around!

Sure! This is the best way I have found. It also allows me to mod a bunch of keys at once, plus, 3d arrays!
