[Resolved] Replacing / removing brackets and text within them

dan744

Hi can somebody explain how to remove brackets from a piece of text and the text within the brackets?

So basically I would like "British Airways (BA / BAW)"
to display "British Airways"

I can obviously remove the quotes with a simple
str_replace("(","",$text);
but how do I comunicate that I want the text within them removing as well?

Thanks in Advance

so basically you want everything after the ( regardless what it is?

Yep, all the text is coming from the database, simply the airline name and then the codes in brackets. The codes in brackets are always the last parts of the text so basically yes everything after and including the (

stolzyboy

ok, this will do what you want

<?
$var = "British Airways (BA / BAW)";
$pos = strpos($var, "(");
$var = substr_replace($var, "", $pos);
echo $var;
?>

but it will leave a space after the airline name, if there is always a space after the airline name and before the (, you can use this

<?
$var = "British Airways (BA / BAW)";
$pos = strpos($var, " (");
$var = substr_replace($var, "", $pos);
echo $var;
?>

I have a related question (I hope you don't mind me hijacking the thread a little bit). How can I insert a space after ever 4 numbers in a 16 number sequence? I am not sure what function to use.

Thanks a lot for that, works a treat!

Just for anyone else needing help with this, if you have any records in the database with no brackets then the replace will start at the begining and delete everything.
Something like this fixes it:

if (!$pos) {
echo("$text");
} else {
echo("$var");
}

where text is your original text and not the replaced text, works great.

Thanks Again!

here ya go n00854180t, hope it works for ya

<?
$var = "1111222233334444";
$one = substr($var, 0, 4);
$two = substr($var, 4, 4);
$three = substr($var, 8, 4);
$four = substr($var, 12, 4);
echo $one . " " . $two . " " . $three . " " . $four;
?>

should echo 1111 2222 3333 4444

Assuming that the 16 digit number is all numbers (i.e no text in it or anything) then something like this should do the trick :

function sepNums($num)
{
    return implode(" ", str_split($num, 4));
}

echo sepNums("1234567890123456");

outputs "1234 5678 9012 3456"

Of course this function doesn't check that the number is infact a 16 digit number but you get the idea.

and... it's for (PHP 5 CVS only)

Thanks! Yeah I can't use php5.

Doh, sorry... didnt think to check it worked on PHP4 since im dev'in for 5 atm.

Heres a revised version 😉

function sepNums($num)
{
    $num = substr($num, 0, 16);
    for($i=0; $i<16; $i+=4)
        $tmpArr[] = substr($num, $i, 4);
    return implode(" ", $tmpArr);
}

echo sepNums("1234567890123456");
