PHP Program cache file Cache processing method

PHP Program cache file Cache processing method
During the development process, the cache settings greatly increase program efficiency and reduce database load.
Basic configuration cache and general configuration cache

The basic configuration cache is formatted like this in project development:

Files: config.php

$CFG [' database '] = ' mysql '; $CFG [' pconnect '] = ' 0 '; $CFG [' db_host '] = ' localhost '; $CFG [' db_name '] = ' appcom '; $CFG [' db_user '] = ' root '; $CFG [' db_pass '] = ' 123456 '; $CFG [' db_charset '] = ' UTF8 ';

The general configuration cache is similar to this: for example, File x.php

return Array (' a ' + = ', ' b ' = = ', ' c ' = = ', ' d ' = = ', ' aa ' = = 'array(' x ' = = ', ' y ' =>, ' z ' = = '), ' BB ' = =array(' x ' = = ', ' y ' =>, ' z ' = = '), ' cc ' = =array(' x ' = = ', ' y ' =>, ' z ' = ' ") ));

Cache Configuration Program code:
Update for basic configuration:

$tmp = file_get (' config.inc.php '); foreach ($settingas$k= +$v)            {$tmppreg_replace(" /[$]cfg\['$k' \]\s*\=\s*[\ "'].*? [\ "']/is '," \ $CFG ['$k'] = '$v$tmp);

General configuration updates: For example, the file name is y.php

Cache_write (' y.php ',$setting);functionCache_write ($file,$string,$dir= ' ') {    if(Is_array($string))$string= "<?php defined (' In_kele ') or exit (' Access Denied '); Return ". STRIP_NR (Var_export($string,true))."; ? > "; $file=$file; $strlen= File_put ($file,$string); return $strlen;}functionSTRIP_NR ($string,$js=false) {    $string=Str_replace(Array(CHR(13),CHR(ten), "\ n", "\ r", "\ T", "'),Array(‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘),$string); if($js)$string=Str_replace("‘", "\‘",$string); return $string;}functionFile_put ($filename,$data) {$phpServer=Strpos(Strtoupper(Php_os), ' WIN ')!==false?true:false; Dir_create (dirname($filename)); if(@$fp=fopen($filename, ' WB ')) {        Flock($fp,lock_ex); $len=fwrite($fp,$data); Flock($fp,Lock_un); fclose($fp); if($phpServer) @chmod($filename,$phpServer); return $len; } Else {        return false; }}functionFile_get ($filename) {    return@file_get_contents($filename);}
