str_replace using wildcards

[gazever]

Hi Can anyone help,

 

I have just spent about an hour googling str replace using wildcards to no joy.

 

Can someone suggest how i would go about replacing: "(3,6) (9)"

 

within a string to: "(3, 6)"

 

however I need to use wildcards for the numbers as these could be "(2,4) (6)" for instance

 

this searching goes thorugh an array containing crossword clues, so not every string will have these specifics, many will just have the number, i.e "(9)"

 

Hope this makes sense!

 

Many Thanks

Look at preg_replace, and if you need help wth a pattern, we have a regex board, but you'll need to be allot clearer in your description.

Regex search:

'/\(([0-9]+),([0-9]+)\) \(([0-9]+)\)/'

 

Regex replace:

'(\1, \2) (\3)'

 

 

I think that should work.

If you are changing files or anything, make sure you backup or are able to undo beforehand.

@thorpe,

 

yup worked a treat, thanks

 

had to replace the brackets first as these interferred with the preg code i think, so changed them before then reverted them back.

 

 

<?php
////// replace --->( and --->) to not mess up the pregreplace
foreach ($newpuzzle as &$value) {
  $value = str_replace("(", "LEFTBRACKET", $value);
  $value = str_replace(")", "RIGHTBRACKET", $value);
}


////// replace "(?,?) (?)" with "(?, ?)" 
foreach ($newpuzzle as &$value) {
$old = '/(LEFTBRACKET)(.*)(,)(.*)(RIGHTBRACKET LEFTBRACKET)(.*)(RIGHTBRACKET)/';
$new = 'LEFTBRACKET${2}${3} ${4}RIGHTBRACKET';
  $newvalue = preg_replace($old, $new, $value);
$value = $newvalue;
}
?>

 

@svivian,

 

Thanks but already sorted the solution from Thorpes suggestion.
