问题描述：在PHP5.4x版本中论坛短消息内容显示空白或不能正常显示中文的解决方案
ucenter在php5.4里，中文短消息无法显示的问题主要是由于uccode.class.php中的htmlspecialchars函数没有经过编码转换，为了解决这个问题，需要对默认的htmlspecialchars进行自定义。
解决方案：
文件：/uc_client/lib/uccode.class.php
查找：function complie($message)
在前面加上：
//解决PHP5.4x版本htmlspecialchars函数中文编码问题
function cr180_dhtmlspecialchars($string, $flags = null)
{
if(is_array($string))
{
foreach($string as $key => $val)
{
$string[$key] = dhtmlspecialchars($val,
$flags);
}
}
else
{
if($flags === null)
{
$string = str_replace(array(‘&‘, ‘"‘, ‘<‘, ‘>‘),
array(‘&‘, ‘"‘, ‘<‘, ‘>‘),
$string);
if(strpos($string, ‘&#‘) !== false)
{
$string = preg_replace(‘/&((#(\d{3,5}|x[a-fA-F0-9]{4}));)/‘,
‘&\\1‘,
$string);
}
} else
{
if(PHP_VERSION < ‘5.4.0‘)
{
$string = htmlspecialchars($string,
$flags);
} else
{
if(strtolower(CHARSET) == ‘utf-8‘)
{
$charset =
‘UTF-8‘;
} else
{
$charset =
‘ISO-8859-1‘;
}
$string = htmlspecialchars($string, $flags,
$charset);
}
}
}
return $string;
}
查找 $message = htmlspecialchars($message);
替换为：$message = $this -> cr180_dhtmlspecialchars($message);
另外，短消息首页无法显示消息内容的问题是由于ucenter函数【lastpm($uid)】里没有提前初始化变量造成的，所以还需要进行以下修改：
文件：/uc_client/model/pm.php
查找：
function lastpm($uid)
{
$lastpm =
$this->db->fetch_first("SELECT *
FROM ".UC_DBTABLEPRE."pm_members m
LEFT JOIN
".UC_DBTABLEPRE."pm_lists t ON m.plid=t.plid WHERE
m.uid=‘$uid‘ ORDER BY m.lastdateline DESC LIMIT
1");
$lastmessage =
unserialize($lastpm[‘lastmessage‘]);
if($lastmessage[‘lastauthorid‘])
{
$lastpm[‘lastauthorid‘] =
$lastmessage[‘lastauthorid‘];
$lastpm[‘lastauthor‘] =
$lastmessage[‘lastauthor‘];
$lastpm[‘lastsummary‘] =
$lastmessage[‘lastsummary‘];
} else
{
$lastpm[‘lastauthorid‘] =
$lastmessage[‘firstauthorid‘];
$lastpm[‘lastauthor‘] =
$lastmessage[‘firstauthor‘];
$lastpm[‘lastsummary‘] =
$lastmessage[‘firstsummary‘];
}
return $lastpm;
}
替换为：
function lastpm($uid)
{
$lastpm = $this->db->fetch_first("SELECT * FROM
".UC_DBTABLEPRE."pm_members m LEFT JOIN ".UC_DBTABLEPRE."pm_lists t ON
m.plid=t.plid WHERE m.uid=‘$uid‘ ORDER BY m.lastdateline DESC LIMIT
1");
<font color="Red"><b>$lastmessage = array();//cr180修正 变量初始化
PHP高版本时可能会造成该变量异常</b></font>
$lastmessage =
unserialize($lastpm[‘lastmessage‘]);
if($lastmessage[‘lastauthorid‘])
{
$lastpm[‘lastauthorid‘] =
$lastmessage[‘lastauthorid‘];
$lastpm[‘lastauthor‘] =
$lastmessage[‘lastauthor‘];
$lastpm[‘lastsummary‘] =
$lastmessage[‘lastsummary‘];
} else
{
$lastpm[‘lastauthorid‘] =
$lastmessage[‘firstauthorid‘];
$lastpm[‘lastauthor‘] =
$lastmessage[‘firstauthor‘];
$lastpm[‘lastsummary‘] =
$lastmessage[‘firstsummary‘];
}
return $lastpm;
}
