$az = "[a-zA-Z']";
$str = str_replace(",", " , ", $str);
$str = str_replace(".", " . ", $str);
$str = trim(preg_replace(array("/ $az /", "/ $az$az /", "/ $az$az$az /"), "

RE: [PHP] Regex function needed
what about words at the start of the string??
eg
$str = "One can see this is or was a test for short words, although an,
should be deleted to.";

this might even work beter, to take comma's and periods etecetera into
account to:
$str = "This is or was a test for short words, although an, should be
deleted to.";
while (ereg(" [a-z]{1,3} ", $str)) {
$str = eregi_replace(" [a-z']{1,3}([ ]{1}|[,]{1}|[.]{1}|[:]{1})", "\\1",
$str);

or even this for comma's etcetera before the words:
$str = "This is or was a test for short words, although an, should be
deleted to.";
while (ereg(" [a-z]{1,3} ", $str)) {
$str =
eregi_replace("([ ]{1}|[,]{1}|[.]{1}|[:]{1})[a-z']{1,3}([ ]{1}|[,]{1}|[.]{1}

Re: [PHP] Regex function needed
I don't know if this is the best way but:
$str = "This is or was a test for short words";
while (ereg(" [a-z]{1,3} ", $str)) {
$str = eregi_replace(" [a-z]{1,3} ", " ", $str);
}
print $str;
this replaces all occurences of a space followed by 1,2 or 3 alphabetic
characters followed by a space... the reason why it's performed in a while
loop is because of two or more short words following each other and thus
sharing a space...
