=== Description ===

Removes trailing newlines and returns the number of characters removed.

=== Parameters ===

==== variable ====

Can be any variable including numbers, strings, arrays.

Note - If it finds an ARRAY it will do the chomp() on every element in the array (but not the keys).

It will chomp elements that are numeric, string or arrays it will not mess with objects etc.

==== delim ====

Optional; Provide a string that each character will be considered a newline delimiter.

Default: "\n"

=== Return Value ===

The character that was removed.

=== Remarks ===

This modifies the string in place.

This function only counts \n as a valid newline however you may provide it with a string you would like it to consider newlines.

=== Example ===

Remove all newlines from end of a string

<syntaxhighlight lang="sputnik">
$cat = "UberFoX\n\n\n\n\n\n";
$rem = chomp($cat);
print "$rem = '$cat'\n";
</syntaxhighlight>

Remove all characters we define as newlines from end of a string

<syntaxhighlight lang="sputnik">
$cat = "UberFoX\n---\r";
$rem = chomp($cat, "-\r\n");
print "$rem = '$cat'\n";
</syntaxhighlight>
