PHP 给输出的字符串添加颜色

废话少说，直接上代码：

#!/usr/bin/php
<?php
class color
{
var $consoleCodes = array();

function color()
{
$this->init();
}

function getConsoleCodes($define)

$fgcolor = '';
$style = '';
$bgcolor = '';
extract($define);

if($fgcolor == 'reset') return "/033[0m";
if(isset($this->consoleCodes['fgcolor'][$fgcolor]))
$codes[] = $this->consoleCodes['fgcolor'][$fgcolor];
if(isset($this->consoleCodes['style'][$style]))
$codes[] = $this->consoleCodes['style'][$style];
if(isset($this->consoleCodes['bgcolor'][$bgcolor]))
$codes[] = $this->consoleCodes['bgcolor'][$bgcolor];

$codes = implode(';', $codes);
return "/033[{$codes}m";
}

function convert($string, $mode = 'replace')
{
foreach($this->convertTable as $controlChar => $controlDefine)
{
if(strpos($string, $controlChar) !== false)
{

{

?>

注：/033 same as ctrl + [ in php (^[ whose ascii code is 0x33)
^[[32mHello => Hello with green
^[[32m^[[5mHello => Hello with blink green
