Note Submitter: Alan Tavares ---- Precisei de uma função para não permitir somente espaços em uma string. Pensei que essa função resolveria meu caso mas espaços são considerados strings e também são diferentes de vazio: Um simples regex resolve o problema: <?php $strings=array( ' ', ' ', ' a', 'a ', 'a' ); foreach ($strings as $string){ echo !eregi('^ {1,}$',$string) ? 'string' : 'not string' ; } ?> O exemplo acima imprime: not string not string string string string Needed a function to not only allow spaces in a string. I thought this function solve my case but spaces are considered strings and are different from empty: A simple regex solve the problem: <?php $strings=array( ' ', ' ', ' a', 'a ', 'a' ); foreach ($strings as $string){ echo !eregi('^ {1,}$',$string) ? 'string' : 'not string' ; } ?> The above example prints: not string not string string string string
