Check for any printable character(s) except space

SYNTAX

ctype_graph ( mixed $text ) : bool

PARAMETERS

text

The tested string.

Note: If an integer between -128 and 255 inclusive is provided, it is interpreted as the ASCII value of a single character (negative values have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string containing the decimal digits of the integer.

RETURN

Returns TRUE if every character in text is printable and actually creates visible output (no white space), FALSE otherwise.
