Big Problem

Cant seem to find any solution to this

 

String 1 'Let's all go on holiday : America'

String 2 'Lets all go on holiday America'

 

When doing a match for this string, I class this as acceptable, However a straight regex will not accept this, Because of the full colon and comma.

 

What I want to achieve, is exactly a case insensitive search, but with some characters to be insensitive about.

To ignore case you just append i to the end of your pattern.

 

I want to pay no attention to ' :, if its there ok, if its not and the rest matchs ok

 

Thanks in advance.

Update.

 

I just noticed one possible way this "may" be possible, havnt tested yet.

 

What if I was to append a ? to each insensitive character in the string.

 

This would tell regex to either find a , or : and match regardless.

 

PS, If this does work, I would still like to hear your answer if you have alternatives, I believe there may be other ways to achieve this.

 

Thanks all

Just a little update guys, I tested my above possible solution, and it worked, But I would appreciate some other alternatives as im sure there are some.

What is it exactly that you want to match? What is your current code?

 

$regex = "/Let'?s all go on holiday (: )?America/i";

foreach (array("Let's all go on holiday : America", "Lets all go on holiday America") as $text) {
  if (preg_match($regex, $text, $matches)) {
    echo '<div style="color: green">' . $text . '</div>';
  } else {
    echo '<div style="color: red">' . $text . '</div>';
  }
}

  } else {
    echo '<div style="color: red">' . $text . '</div>';
  }
}

The solution I just done works like this

$search =  'Rule Britanni'a King of : All';

$ignore[0] = array(',',':');
$ignore[1] = array(',?',':?');

$string = str_replace($ignore[0],$ignore[1],$string);

preg_match("/$string/i",$search,$match);

var_dump($match);

This actually works fine, But wondered if there are other solutions quicker/better then what I have done
