preg_match

[Nel]

Please can someone help me with this before I explode!!! (no pun intended)

<?php
// EXAMPLE 1
$text = "This is Driving me mad";
$check = "Driving";
$ss = "([ ][0-9a-zA-Z ½\',\.]{0,30}".$check. "[0-9a-zA-Z ½\',\.]{0,30}[ ])";
preg_match($ss, $text,$check);
echo "result = $check[0]"; //gives a result

echo "<br>";

// EXAMPLE 2
$text = "This is Driving me mad";
$check = "driving"; // NOTE CHANGE Driving to driving
$ss = "([ ][0-9a-zA-Z ½\',\.]{0,30}".$check. "[0-9a-zA-Z ½\',\.]{0,30}[ ])";
preg_match($ss, $text,$check);
echo "result = $check[0]"; // gives nothing.

?>


According to php.net /i is required to make it case sensitive, so why is
this happening?!?!

])`i";

Thanks Justin.

All the documentation says to use /i at the end of the string.

http://php.us.themoes.org/manual/en/function.preg-match.php

I have spent ages trying to fit /i somewhere, anywhere to make it work.

You may well have saved my sanity :-)

It's onlt /i if you use the "/" as the regex delimiter. In my reply, I
used the backtick "`" instead (I do that so I don't have to escape all
my "/" characters.

Here's a little more reading (just search for perl regex or perl regular
expressions to find a whole lot more!):

And the ones I'm sure you've found already:
