Here it is, but I used preg instead:
<?
$str = "Mot1;;Mot2;;;;;;;;;;;;;Mot3;;;;;;Mot4;;;;;;;Mot5;;;;Mot6";
echo "Before: " . $str . "<p>";
/*
while ( strstr(";;", $str) ) ## if exists ;; in $str, replace with 1 ;
{
$str = str_replace( ";;", ";", $str );
}
*/
while( preg_match( "/;;/", $str ) )
{
$str = preg_replace( "/;;/", ";", $str );
}
echo "After: " . $str;
?>
And it works!
;)
