Manual
Code Examples

ctype_graph( mixed$text ): bool

Checks if all of the characters in the provided string, text, creates visible output.

Parameters

text

The tested string.

Note:

If an int 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.

Warning:

As of PHP 8.1.0, passing a non-string argument is deprecated. In the future, the argument will be interpreted as a string instead of an ASCII codepoint. Depending on the intended behavior, the argument should either be cast to string or an explicit call to chr should be made.

Return Values

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