    Capítulo 68. Zend_Text

    68.1. Zend_Text_Figlet

    Zend_Text_Figlet is a component which enables developers to create a so called FIGlet text. A FIGlet text is a string, which is represented as ASCII art. FIGlets use a special font format, called FLT (FigLet Font). By default, one standard font is shipped with Zend_Text_Figlet, but you can download additional fonts at

    [Nota] Compressed fonts

    Zend_Text_Figlet supports gzipped fonts. This means that you can take an .flf file and gzip it. To allow Zend_Text_Figlet to recognize this, the gzipped font must have the extension .gz. Further, to be able to use gzipped fonts, you have to have enabled the GZIP extension of PHP.

    [Nota] Encoding

    Zend_Text_Figlet expects your strings to be UTF-8 encoded by default. If this is not the case, you can supply the character encoding as second parameter to the render() method.

    You can define multiple options for a FIGlet. When instantiating Zend_Text_Figlet, you can supply an array or an instance of Zend_Config.

    • font - Defines the font which should be used for rendering. If not defines, the built-in font will be used.

    • outputWidth - Defines the maximum width of the output string. This is used for word-wrap as well as justification. Beware of too small values, they may result in an undefined behaviour. The default value is 80.

    • handleParagraphs - A boolean which indicates, how new lines are handled. When set to TRUE, single new lines are ignored and instead treated as single spaces. Only multiple new lines will be handled as such. The default value is FALSE.

    • justification - May be one of the values of Zend_Text_Figlet::JUSTIFICATION_*. There is JUSTIFICATION_LEFT, JUSTIFICATION_CENTER and JUSTIFICATION_RIGHT The default justification is defined by the rightToLeft value.

    • rightToLeft - Defines in which direction the text is written. May be either Zend_Text_Figlet::DIRECTION_LEFT_TO_RIGHT or Zend_Text_Figlet::DIRECTION_RIGHT_TO_LEFT. By default the setting of the font file is used. When justification is not defined, a text written from right-to-left is automatically right-aligned.

    • smushMode - An integer bitfield which defines, how the single characters are smushed together. Can be the sum of multiple values from Zend_Text_Figlet::SM_*. There are the following smush modes: SM_EQUAL, SM_LOWLINE, SM_HIERARCHY, SM_PAIR, SM_BIGX, SM_HARDBLANK, SM_KERN and SM_SMUSH. A value of 0 doesn't disable the entire smushing, but forces SM_KERN to be applied, while a value of -1 disables it. An explanation of the different smush modes can be found here. By default the setting of the font file is used. The smush mode option is normally used only by font designers testing the various layoutmodes with a new font.

    Exemplo 68.1. Using Zend_Text_Figlet

    This example illustrates the basic use of Zend_Text_Figlet to create a simple FIGlet text:

    $figlet = new Zend_Text_Figlet();

    Assuming you are using a monospace font, this would look as follows:

      ______    ______    _  __   ______
    |__  //   |  ___||  | \| || |  __ \\
    //    | ||__    |  ' || | |  \ ||
    //__   | ||___   | .  || | |__/ ||
    /_____||  |_____||  |_|\_|| |_____//
    `-----`'  `-----`   `-` -`'  -----`
