Zend_Text_Table - Zend_Text
Zend_Text_Table is a component to create text based tables on the fly with different decorators. This can be helpful, if you either want to send structured data in text emails, which are used to have mono-spaced fonts, or to display table information in a CLI application. Zend_Text_Table supports multi-line columns, colspan and align as well.
Zend_Text_Table expects your strings to be UTF-8 encoded by default. If this is not the case, you can either supply the character encoding as a parameter to the constructor() or the setContent() method of Zend_Text_Table_Column. Alternatively if you have a different encoding in the entire process, you can define the standard input charset with Zend_Text_Table::setInputCharset($charset). In case you need another output charset for the table, you can set this with Zend_Text_Table::setOutputCharset($charset).
A Zend_Text_Table object consists of rows, which contain columns, represented by Zend_Text_Table_Row and Zend_Text_Table_Column. When creating a table, you can supply an array with options for the table. Those are:
columnWidths (required): An array defining all columns width their widths in characters.
decorator: The decorator to use for the table borders. The default is unicode, but you may also specify ascii or give an instance of a custom decorator object.
padding: The left and right padding withing the columns in characters. The default padding is zero.
AutoSeparate: The way how the rows are separated with horizontal lines. The default is a separation between all rows. This is defined as a bitmask containing one ore more of the following constants of Zend_Text_Table:
Rows are simply added to the table by creating a new instance of Zend_Text_Table_Row, and appending it to the table via the appendRow() method. Rows themselves have no options. You can also give an array to directly to the appendRow() method, which then will automatically converted to a row object, containing multiple column objects.
The same way you can add columns to the rows. Create a new instance of Zend_Text_Table_Column and then either set the column options in the constructor or later with the set*() methods. The first parameter is the content of the column which may have multiple lines, which in the best case are separated by just the '\n' character. The second parameter defines the align, which is 'left' by default and can be one of the class constants of Zend_Text_Table_Column:
To finally render the table, you can either use the render() method of the table, or use the magic method __toString() by doing echo $table; or $tableString = (string) $table.
Example #1 Using Zend_Text_Table
This example illustrates the basic use of Zend_Text_Table to create a simple table:
This will result in the following output:
