IntlChar::isgraph — Check if code point is a graphic character
public static IntlChar::isgraph ( mixed $codepoint ) : bool
Determines whether the specified code point is a "graphic" character (printable, excluding spaces).
true
for all characters except those with general categories "Cc" (control codes), "Cf" (format controls), "Cs" (surrogates), "Cn" (unassigned), and "Z" (separators).
codepoint
The int codepoint value (e.g. 0x2603
for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}"
)
Returns true
if codepoint
is a "graphic" character, false
if not.
Example #1 Testing different code points
<?php var_dump(IntlChar::isgraph("A")); var_dump(IntlChar::isgraph("1")); var_dump(IntlChar::isgraph("\u{2603}")); var_dump(IntlChar::isgraph("\n")); ?>
The above example will output:
bool(true) bool(true) bool(true) bool(false)
