explode() & implode()
Some PHP classics.
explode(delimiter, string, limit); - returns an array from a string, split by the given delimiter. Optionally, a limit can be supplied.
- delimiter: a boundary string
- string: the source string
- limit: if limit is set, the returned array will contain a maximum number of limit elements, with remaining part of string attached to the last element. If limit is negative, all but the last limit elements are returned.
Note that if delimiter is set to an empty string ("") or 0, explode() will return FALSE.
PHP Code:
function explode(delimiter, string, limit) {
temp.tokens = temp.string.tokenize(temp.delimiter);
if(!temp.delimiter || temp.delimiter == "") {
return false;
}
if(!temp.limit || temp.limit == 0) {
return temp.string.tokenize(temp.delimiter);
}
if(temp.limit > temp.tokens.size()) {
temp.limit = temp.tokens.size();
}
else if(temp.limit > 0) {
for(temp.i = 0; temp.i <= temp.limit - 1; temp.i ++) {
temp.output.add(temp.tokens[temp.i]);
}
for(temp.i = 0; temp.i < temp.tokens.size() - temp.limit; temp.i ++) {
temp.output[temp.limit - 1] @= temp.delimiter @ temp.tokens[temp.limit + temp.i];
}
}
else {
temp.limit *= -1;
for(temp.i = 0; temp.i <= temp.limit - 1; temp.i ++) {
temp.output.add(temp.tokens[temp.i]);
}
}
return temp.output;
}
Example:
PHP Code:
function onCreated() {
temp.string = "this!is!my!string";
temp.i = explode("!", temp.string);
temp.i2 = explode("!", temp.string, 2);
temp.i3 = explode("!", temp.string, -2);
echo("Starting string: " @ temp.string);
echo("Exploded: " @ temp.i @ "; " @ temp.i2 @ "; " @ temp.i3);
}
Returns:
Quote:
Starting string: this!is!my!string
Exploded: this,is,my,string; this,is!my!string; this,is

implode(glue, pieces); - joins array elements with an optional glue string.
- glue: the separating string
- pieces: an array
PHP Code:
function implode(glue, pieces) {
for(temp.i = 0; temp.i < temp.pieces.size(); temp.i ++) {
if(temp.glue) {
if(temp.i != temp.pieces.size() - 1) {
temp.output @= temp.pieces[temp.i] @ temp.glue;
}
else {
temp.output @= temp.pieces[temp.i];
}
}
else {
temp.output @= temp.pieces[temp.i];
}
}
return temp.output;
}
Example:
PHP Code:
function onCreated() {
temp.pieces = {
"this", "is", "my", "array"
};
temp.i = implode(null, temp.pieces);
temp.i2 = implode(",", temp.pieces);
temp.i3 = implode("#", temp.pieces);
temp.i4 = implode("-+-", temp.pieces);
echo("Starting array: " @ temp.pieces);
echo("Imploded: " @ temp.i @ "; " @ temp.i2 @ "; " @ temp.i3 @ "; " @ temp.i4);
}
Returns:
Quote:
Starting array: this,is,my,array
Imploded: thisismyarray; this,is,my,array; this#is#my#array; this-+-is-+-my-+-array
