Add the following code to the above (NB think you're a } short):
$RegExIn = "3,43m)";
echo "<br><br>With RegEx: $RegExIn";
$RegExPattern = "/(\d{1,3})(,)(\d{1,3})([a-z]{1,2})(.*)/i";
echo "<br>RegEx ~$RegExPattern~";
$bValidity = $iFound
= preg_match( $RegExPattern, $RegExIn, $aRegExOut );
if ( FALSE === $bValidity )
{
$aLocated = NULLSTRING;
echo '<br>Error interpreting RegEx';
}
if ( 0 == $iFound )
{
$aLocated = NULLSTRING;
}
if ( 0 < $iFound )
{
echo "<br>First number =" . $aRegExOut[1];
echo "<br>Separator =" . $aRegExOut[2];
echo "<br>Second number =" . $aRegExOut[3];
echo "<br>Text unit =" . $aRegExOut[4];
echo "<br>Additional non-text =" . $aRegExOut[5];
$value = $aRegExOut[1] . "." . $aRegExOut[3];
echo "<br>Value = $value";
}
Totally unsure about $last2ontime.
The RegEx has been structured fairly loosely because I'm not sure of all
the
specifications for how many digits can be in the various places, etc; so
feel free to altered the repetition values (inside the curly brackets)
to
suit. Of course, if the comma is missing or there is no integer value,
(etc), then the whole thing will fall apart and give you nothing (hence
the
$aLocated = NULLSTRING; line which should probably be reworded/tied back
to
$value (yes I was reusing old code))!
Hope it helps,
=dn
Sweet!
It worked perfectly as I needed it to and I get to remove a lot of extra
code from my script.
Thank you bunches,
Mike
