Because it is simple and efficient:
$s = 'variable chars anchor want this';;
$s = substr $s, index $s,'anchor';;
print $s;;
anchor want this
If I was going to use a regex (say the anchor had a variable component), then:
$s = 'variable chars anchor want this';;
$s =~ s[.+(?=anchor)][];;
print $s;;
anchor want this
The difference:
cmpthese -1,{
a=> q[$s='variable chars anchor want this';$s=~s[.+(?=anchor)][];]
+,
b=> q[$s='variable chars anchor want this';$s=substr $s, index $s,
+'anchor';]
};;
Rate a b
a 1592446/s -- -48%
b 3055291/s 92% --
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.

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).
