I have a string and want to alter all the instances of a certain character within in it. Here is my feeble attempt:
$instring = "This-is-my-string";
$outstring = "";
for ($i=0; $i length $instring; $i++)
{
if ($instring[$i] ne "-")
{
$outstring .= $instring[$i];
}
else
{
# replace with a new character or substring
$outstring .= "_";
}
}
print "$outstring";
The desired out put would be "This_is_my_string"

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
