|

The line of code:
|
|
<informalexample>
|
|
<programlisting role="php">
|
|
<![CDATA[
|
|
<?php
|
|
$var = strspn("42 is the answer, what is the question ...", "1234567890");
|
|
?>
|
|
]]>
|
|
</programlisting>
|
|
</informalexample>
|
|
will assign 2 to <varname>$var</varname>, because the string "42" will
|
|
be the longest segment containing characters from "1234567890".
|
|
</para>
|

<simpara>

|
As of PHP 4.3.0, <function>strspn</function> accepts two optional
|
|
<type>integer</type> parameters that can be used to define the
|
|
<parameter>start</parameter> position and the
|
|
<parameter>length</parameter> of the string to examine.
