Sorry, but neither of these suggestions work on my server, and it would
probably run into problems if one of the "Mot"s had a _ at the beginning or
end. Nicola's first offering gives:
Mot1_;Mot2_;_;_;_;_;_;_;_Mot3_;_;_;Mot4_;_;_;_;_Mot5_;_;Mot6
The second one gives:
Mot1;Mot2;;;;;;;_Mot3;;;Mot4;;;;_Mot5;;Mot6
My solution? Recursively replace ";;" with ";" until the string doesn't get
any shorter. This one works and is pretty neat:
<?
$str = "Mot1;;Mot2;;;;;;;;;;;;;Mot3;;;;;;Mot4;;;;;;;Mot5;;;;Mot6";
$length=-1;
while ($length != strlen($str)) {
$length = strlen($str);
$str = str_replace(";;", ";", $str);
}
echo $str;
?>
Returns:
Mot1;Mot2;Mot3;Mot4;Mot5;Mot6
as required

Ross

Subject: RE: [PHP-WIN] String reduce
I added the underscore artificially in order to make the string become
Mot1_;__;_Mot2_;__;__;__;__;__;__;__;__;__;_Mot3_;__;__;_andsoon;;;M
ot4;;;;;;;Mot5;;;;Mot6
so ONLY the first(s) ";" begin with just ONE underscore
the other begins with 2 underscores, so you can recognize them
and strip them away.
the correct version would be
$str = "Mot1;;Mot2;;;;;;;;;;;;;Mot3;;;;;;Mot4;;;;;;;Mot5;;;;Mot6";
$str = str_replace(";", "_;_", $str);
$str = str_replace("__;_", "", $str);
$str = str_replace("_;", ";", $str);
The string is:
Mot1;;Mot2;;;;;;;;;;;;;Mot3;;;;;;Mot4;;;;;;;Mot5;;;;Mot6
then becomes
$str = str_replace(";", "_;_", $str);
Mot1_;__;_Mot2_;__;__;__;__;__;__;__;__;__;_Mot3_;__;__;_andsoon;;;M
ot4;;;;;;;Mot5;;;;Mot6
then becomes
$str = str_replace("__;_", "", $str);
Mot1_;Mot2_;Mot3_;Mot4_;Mot5_;Mot6
then becomes
$str = str_replace("_;", ";", $str);
Mot1;Mot2;Mot3;Mot4;Mot5;Mot6
It's horrible but it works... ( yet I didn't test it )
Bye
