  • HaruPage::measureText()

    (PECL haru >= 0.0.1)

    Calculate the byte length of characters which can be included on one line of the specified width

    说明

    HaruPage::measureText(string $text,float $width[,bool $wordwrap= FALSE]): int

    Get the byte length of characters which can be included on one line of the specified width.

    参数

    $text

    The text to measure.

    $width

    The width of the line.

    $wordwrap

    When this parameter is set to TRUE the function "emulates" word wrapping by stopping after the last full word(delimited by whitespace)that can fit on the line.

    返回值

    Returns the byte length of characters which can be included within the specified width. For single-byte encodings, this is equal to the number of characters. For multi-byte encodings, this is not necessarily the case.
