PHP Regular Expression Pattern Matching

I have various dynamic strings in PHP that I am trying to split

$string = "Man Utd v Liverpool - Premiership";
$string = "World Championships - Oslo - Ski Jumping";
$string = "Regional Heats - Sussex - UK - Tiddliwinks";

I need to split the strings based on the LAST " - " to read

$string = "Man Utd v Liverpool";
$string = "World Championships - Oslo";
$string = "Regional Heats - Sussex - UK";

How can I do this? My Regular Expression Pattern skils are very basic.

Thanks

Mike

Try this

<?php

$string = array();

$string[] = "Man Utd v Liverpool - Premiership";
$string[] = "World Championships - Oslo - Ski Jumping";
$string[] = "Regional Heats - Sussex - UK - Tiddliwinks";
$string[] = "Man Utd v Liverpool";
$string[] = "World Championships - Oslo";
$string[] = "Regional Heats - Sussex - UK";

foreach( $string as $aString ) {

     preg_match('#^(.+?)-([^-]+)$#', $aString, $match );


     // show results
     //
     echo "Original: '$aString'<br/>";
     echo "<pre>";
     print_r($match);
     echo "</pre>";
     echo "<br/>";

}

Open in new window


Which gives

Original: 'Man Utd v Liverpool - Premiership'

Array
(
    [0] => Man Utd v Liverpool - Premiership
    [1] => Man Utd v Liverpool
    [2] =>  Premiership
)


Original: 'World Championships - Oslo - Ski Jumping'

Array
(
    [0] => World Championships - Oslo - Ski Jumping
    [1] => World Championships - Oslo
    [2] =>  Ski Jumping
)


Original: 'Regional Heats - Sussex - UK - Tiddliwinks'

Array
(
    [0] => Regional Heats - Sussex - UK - Tiddliwinks
    [1] => Regional Heats - Sussex - UK
    [2] =>  Tiddliwinks
)


Original: 'Man Utd v Liverpool'

Array
(
)


Original: 'World Championships - Oslo'

Array
(
    [0] => World Championships - Oslo
    [1] => World Championships
    [2] =>  Oslo
)


Original: 'Regional Heats - Sussex - UK'

Array
(
    [0] => Regional Heats - Sussex - UK
    [1] => Regional Heats - Sussex
    [2] =>  UK
)
