Question

我注意到这个问题的目的是替换。这些部分整体上显示在MySQL数据库的1000个条目中。我需要理解处理多个替换（如何这样做）以及是通过php函数还是通过mysql中的命令行执行。

将空白替换为空（代码可能因地而异）：

<div style="margin-top: 3em;">
<h3>The Incandescent Light Bulb Lives!</h3>
<strong><strong><strong> </strong></strong></strong>
<div style="float: left; background-color: #c5c5c5; width: 320px; margin: 0px 8px 22px 0px; padding: 8px; text-align: center;">

2011 Mike Smith

Hey folks, its Mike Mike Smith with today's update.

</div>
<div style="margin-top: 3em;">

The incandescent lightbulb is back, it is legal and the ban, set to begin on January 1, 2012 has been repealed. That is the news across the wires today but it is only partially true. The Republicans in the house stuffed a provision in the $1 Trillion omnibus spending bill that prevents the Department of Energy from spending any money to enforce the ban which is still on the books. This begs the question for conservatives to answer: if Congress can forbid and or defund unconstitutional activities that regulatory agencies are making (like enforcing light bulb bans) then why cant the same Congress just un-fund enforcement of say The Endangered Species Act or the equally nefarious activities of the NLRB?Why couldnt Congress not fund ObamaCare? Why couldnt Congress un fund GM or AIG or bailouts to Fannie Mae and Freddie Mac? The answer is of course, Congress CAN ban those expenditures or just not fund them but this would take political courage and outside of standing shoulder to shoulder with Tom Edison what courage have we seen from them? The same can be said of almost any agency or activity that federal regulators are engaging in and people are demanding relief from. This seems like a perfect way to teach some constitutionalism to new members AND to secure Congressional conservatives budget cutter bonafides too but alas, the light bulb act seems to be a loss leader for censuring big government by starving it of funds.

The next time you hear rigorous debate about how best to minimize the impact that the Feds have in say our public schools remember that their activity is funded by the Congress that proved it does not have to spend a dime on anything it does not want to including other bright ideas like studying monkeys high on the DEAs cocaine. Now who is the dim bulb that appropriated funds for that!?

Answer 1

这是如何做到的

编写一个PHP脚本实现以下伪代码（对于完整的代码，最好在一些自由职业网站上查询）：

运行查询SELECT fields to replace FROM table
迭代所有记录，一个接一个地进行替换：

while($row=mysql_fetch_assoc($res)) {
    $data = $row['field'];
    $data = preg_replace('pattern','replace', $data);
    $data = preg_replace('pattern','replace', $data);
    $data = preg_replace('pattern','replace', $data);
    // and so on, whaever replacements you need.

    // same goes for the other fields, if any:
    $data1 = $row['field1'];
    $data1 = preg_replace('pattern','replace', $data1);
    $data1 = preg_replace('pattern','replace', $data1);

    //and finally, by having all your replacements done, run an UPDATE query

    $data = mysql_real_escape_string($data);
    $data1 = mysql_real_escape_string($data1);
    $sql = "UPDATE table SET field='$data', field1='$data1' WHERE id=".$row['id'];
    mysql_query($sql) or trigger_error(mysql_error()." ".$sql);
}

Answer 2

让我们以第二个为例，因为它是最短的。然后我将与它一起展示一个简短的其他例子。

UPDATE `table` SET `column` = REPLACE(`column`,'{audio}Why Congress Cannot Impose A Uniform Rule Of Tyranny ||http://mikesmith.com/mikes_audio/Dec_2011/20111219_church__sponsored.mp3{/audio}','') 
WHERE `column` LIKE '%{audio}Why Congress Cannot Impose A Uniform Rule Of Tyranny ||http://mikesmith.com/mikes_audio/Dec_2011/20111219_church__sponsored.mp3{/audio}%';
UPDATE `table` SET `column` = REPLACE(`column`,'BAD TEXT','')
WHERE `column` LIKE '%BAD TEXT%');

这是否有意义并解决问题？
