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) {

复制代码
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;
}

复制代码
查找：

$message = htmlspecialchars($message);

复制代码
替换为：

$message = $this -> cr180_dhtmlspecialchars($message);

复制代码

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;
}

复制代码
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");
$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
$lastmessage = unserialize($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;
}
