求正则表达式

[hufeikong]

替换字符串中的 width="325325" 为 width="216"的正则表达式

[cuiyang000]

$str='width="325325"';
preg_replace("(\d+)", "216", $str);

或者$str='width="325325"';
str_replace("325325", "216", $str);

:)

[hufeikong]

不是这个意思
我要用preg_replace替换已知字符串中所有的width="????" 为width="216"

[hufeikong]

写成这样,但是不对!不知道原因
$str=preg_replace('(width=\"*\")','width="260"',$str)

[cuiyang000]

$str=preg_replace('(width=\"\d+\")','width="260"',$str);

[hufeikong]

$str=preg_replace('(width=\"\d+\")','width="260"',$str);
不行啊,运行了,没有匹配到

[cuiyang000]

我试过,完全可以

$str='wqdqw qdqwdqd width="325325"  qwdqwdqwdqw';
$str=preg_replace('(width=\"\d+\")','width="260"',$str);
echo $str;

要不你把你整个$str贴出来我看看

[hufeikong]

测试例子,没有成功.
$str='<align="middle" height="360" width="480">';
$str=preg_replace('(width=\"\d+\")','width="260"',$str);

[cuiyang000]

可是...明明成功了呀...

$str=' <align="middle" height="360" width="480">';
$str=preg_replace('(width=\"\d+\")','width="260"',$str);
echo htmlspecialchars($str); 

[cuiyang000]

或者不用htmlspecialchars, 直接查看源代码也行,确实是成功了.

[hufeikong]

那就奇怪了,我是在帝国cms里面写的

bqr[newstext]中含有width="480"

<?
$str=preg_replace('(width=\"\d+\")','width="260"',$bqr[newstext]);
$str=preg_replace('(height=\"\d+\")','height="216"',$str);
?>
<?=$str?>

一直没有成功

<object class="OBJECT" id="MediaPlayer" classid="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95" width="480" height="360" align="middle">

[cuiyang000]

这我就不清楚了``那个$bqr[newstext]是不是需要转换一下字符格式之类的?

[cuiyang000]

直接

$str='<object class="OBJECT" id="MediaPlayer" classid="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95" width="480" height="360" align="middle">
<param name="AUTOSTART" value="false" />
<param name="ShowStatusBar" value="-1" />
<param name="Filename" value="/d/file/shipindianbo/2009-10-15/64a2790d9392db0fe4fc24206af3205b.wmv" /> <embed width="480" height="360" type="application/x-oleobject codebase=http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701" src="/d/file/shipindianbo/2009-10-15/64a2790d9392db0fe4fc24206af3205b.wmv" flename="mp"> </embed> </object>';

$str=preg_replace('(width=\"\d+\")','width="200"',$str);
echo htmlspecialchars($str); 

都是可以的...

[hufeikong]

郁闷,单独写个test确实是替换了,在帝国里就是木有替换!!!!!!!!!!

<?
$str='<object class="OBJECT" id="MediaPlayer" classid="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95" width="480" height="360" align="middle"> 
<param name="AUTOSTART" value="false" /> 
<param name="ShowStatusBar" value="-1" /> 
<param name="Filename" value="/d/file/shipindianbo/2009-10-15/64a2790d9392db0fe4fc24206af3205b.wmv" /> <embed width="480" height="360" type="application/x-oleobject codebase=http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701" src="/d/file/shipindianbo/2009-10-15/64a2790d9392db0fe4fc24206af3205b.wmv" flename="mp"> </embed> </object>';
$str=preg_replace('(width=\"\d+\")','width="260"',$str);
$str=preg_replace('(height=\"\d+\")','height="216"',$str);
?>
<?=$str?>

[cuiyang000]

呃..爱莫能助了...把那个$bqr[newstext]转换下行吗?用htmlspecialchars之类的`然后正则`然后再转回来???我也不懂了...祝你好运吧
