Define value edit by another php file - php

Question

I have 2 questions
1.) how to write update_defile($array_value){...} function?
define_file.php
<?php
define("FIST_NAME", "something1");
define("LAST_NAME", "something2");
define("ADDRESS", "something3");
?>
"something" is not a constant value that can be change every method Call(update_defile($array_value)
value set
$array_value = ("FIST_NAMe" => "duleep", "LAST_NAME" => "dissnayaka", "AGE" => "28" );
after call method(update_defile($array_value){.....}) "define_file.php"
file want to be look like bellow
<?php
define("FIST_NAME", "duleep");
define("LAST_NAME", "dissnayaka");
define("ADDRESS", "something3");
define("AGE", "28");
?>
2).
My datbase is Oracle. I already saved configuration value in the data base but frequently use these configuration value for my application. So i get value form database and save in the define_file.php as increase performance(down rate database call) but I'm not sure i can increase performance keep configuration value in the PHP file please explain. what is the best way increase performance my application and other alternative solutions welcome.

Why cant u use session to store such values , then u can access and modify from anywhere
in the script.
<?php
session_start();
$_SESSION["FIST_NAME"]= "something1";
$_SESSION["LAST_NAME"]= "something2";
$_SESSION["ADDRESS"]= "something3";
?>

public function update($form_config_arr)
{
if( (is_readable($config_file_path)) && is_writable($config_file_path))
{
if(!$config_old_file_content = file_get_contents($config_file_path))
{
throw new Exception('Unable to open file!');
}
$i = 0;
$config_old_arr = array();
$config_new_arr = array();
foreach ($form_config_arr as $constant => $value){
$config_old_line = $this->getLine($constant);
$config_old_arr[$i] = $config_old_line;
if(($value == 'true') || ($value == 'false')){
$config_new_arr[$i] = "define ( '$constant', $value );\n";
}else{
$config_new_arr[$i] = "define ( '$constant', '$value' );\n";
}
$i++;
}
$config_new_file_content = str_replace($config_old_arr, $config_new_arr, $config_old_file_content);
$new_content_file_write = file_put_contents($config_file_path, $config_new_file_content);
foreach ($config_new_arr as $constant => $value)
{
echo $value.'<br/>';
}
return true;
}else{
throw new Exception('Access denied for '.$config_file_path);
return false;
}
}
/**
*
* #param string $constant
* #return string
*/
private function getLine($constant)
{
$match_line = '';
$config_file = fopen($config_file_path, "r");
if($config_file)
{
//Output a line of the file until the end is reached
$i = 0;
while(!feof($config_file))
{
$i++;
$config_old_line = fgets($config_file);
$pos = strpos($config_old_line, $constant);
if( $pos !== false )
{
$match_line= $config_old_line;
}
}
fclose($config_file);
return $match_line;
}else{
throw new Exception('Unable to open file!');
}
}

What you are trying to do is edit a file.
Simply create another php script: updater.php
It should poll the database, fetch the values and update the values in define_file.php
Look for php file handling functions here: http://www.w3schools.com/php/php_file.asp
