<div class="content wysiwyg-content">
hello,<br />
there is a long string,the content is:<br />
<br />
&nbsp;$str=&quot;name1(432)\n<br />
&nbsp; &nbsp; &nbsp; &nbsp;name2(89)\n<br />
&nbsp; &nbsp; &nbsp; &nbsp;name3(3423)\n<br />
&nbsp; &nbsp; &nbsp; &nbsp;name1(21)\n&quot;;<br />
the problem is I want to delete some name and its value from &nbsp;$str and only once searching from end(reverse order).<br />
for example:<br />
&nbsp;if I specify &quot;name1&quot;(its value not given),the result should be: &nbsp;$str=&quot;name1(432)\n<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; name2(89)\n<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;name3(3423)\n&quot;<br />
Thanks.

       name1(21)\n";
the problem is I want to delete some name and its value from  $str and only once searching from end(reverse order).
for example:

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.
