## Strings2-Functions
##
## (c) 1998 Alex 'SSilk' Aulbach
##
## These Functions are very practical and if I could program
## C a little bit better it will be placed directly in PHP3.
## But I can't... :-}

##
## Have you ever worried about such constructs like
## echo ($faxnumber) ? sprintf("Fax: %s",$faxnumber) : "";
##
## This functionset could help you to replace those constructs by
## p_iftrue($faxnumber,"Fax: %s");
## which is nearly the half of typing and looks more clear and solves
## an error if $faxnumber is unset.
##
function o_iftrue ($val,$str) {
if (isset($val) && $val) {
return(sprintf($str,$val));
}
}
function p_iftrue ($val,$str) {
print o_iftrue($val,$str);
}
##
## Output "One or More"
##
## This function is good if you want to differ a output by number:
## e.g. o_1or2($q->num_rows(),
## "Found only one matching record",
## "Found %s records");
## Will output if num_rows() is 1: "Found only one matching record"
## 200: "Found 200 records"
##
## if $val is empty() or "" a blank string will be returned!
##
function o_1or2 ($val,$str1,$str2) {
if (isset($val) && $val) {
if (1==$val) {
return(sprintf($str1,$val));
} else {
return(sprintf($str2,$val));
}
} else {
return(false);
}
}
function p_1or2 ($val,$str1,$str2) {
print o_1or2 ($val,$str1,$str2);
}
##
## This is for the case, that you want to output something
## if $val is false e.g.
##
## p_0or1($faxnumber,"THERE IS NO FAXNUMBER","Faxnumber: %s");
##
function o_0or1 ($val,$str1,$str2) {
if (empty($val) || !$val) {
if (isset($val)) {
return(sprintf($str1,$val));
} else {
return($str1);
}
} else {
return(sprintf($str2,$val));
}
}
function p_0or1 ($val,$str1,$str2) {
print o_0or1 ($val,$str1,$str2);
}
##
## Replaces all blank-chars with
## This function is used, when you are not willing to let the browser
## break your lines an can be used instead of <NOBR>-Tag
## as very compatible replacement
##
## can also be replaced by a true whitespace which has in
## ISO-latin-1 the code 160
##
function o_nonbsp ($val) {
return(ereg_replace("[[:blank:]\n\r]"," ",$val));
}
function p_nonbsp ($val) {
print o_nonbsp($val);
}
