Question

How can I make the following regular expression ignore all whitespaces?

$foo = ereg_replace("[^áéíóúÁÉÍÓÚñÑa-zA-Z]", "", $_REQUEST["bar"]);

Input: Ingeniería Eléctrica’*;<42

Current Output: IngenieríaEléctrica

Desired Output: Ingeniería Eléctrica

I tried adding /s \s\s* \s+ /\s+/ /s /t /r among others and they all failed.

Objective: A regex that will accept only strings with upper or lower case characters with or without (spanish) accents.

Thank you !

I see no reason as to why adding \s to that regex would not work. \s should match all whitespace characters.

$foo = preg_replace("/[^áéíóúÁÉÍÓÚñÑa-zA-Z\s]/", "", $_REQUEST["bar"]);
