added "bgColor" fontStyle, "exactHeight" tableRowStyle and minor modifs for php://output

BGCOLOR:

• Meant to replace fgColor, can use any hex color instead of the 15 color constants in Font.php
• usage: $section->addText(" myText ", array("bgColor" => "112233"));
• I found out that spaces after words cannot be highlighted (the same happens with fgColor)
  my temporary fix is replacing all space with the htmlCode of a space so if you really need this feature, add this around line 78 in Word2007/Base.php, just before $objWriter->writeRaw($strText);
  $strText = str_replace(" ", " ", $strText);
• sample is in samples/Sample_20_BGColor.php

TABLE ROW STYLE EXACTHEIGHT

• added exactHeight for table row styling
• mostly for removing the auto-added space after elements in a cell
• usage: $table->addRow($height, array("exactHeight" => true));
• sample is in samples/Sample_21_TableRowRules.php

MODIFS PHP://OUTPUT

• Tmp file should go into sys_get_temp_dir() instead of "./"
• added content-length header to get the total filesize when downloading

@jcarignan Could you add some unit tests and documentation ?

[ivanlanin]

@jcarignan I suggest to use row style (the $style in addRow) to put the height rule. It will be the same like $tblHeader and $cantSplit. We will reduce the number of parameters passed to addRow.

[jcarignan]

@ivanlanin heightRule is now in row style!
new usage is $table->addRow($height, array("heightRule"=>"exact"));

@Progi1984 Still trying to figure out how to add unit tests, but documentations is coming soon..!

[ivanlanin]

Thanks. I'll review and merge your code ASAP.

[jcarignan]

@ivanlanin Seems like the other values of heightRule are useless to users ("auto" and "atLeast"):
If we don't set an height to the row, the heightRule is set to "auto" and it uses the height of the content.
If we do set an height to the row, heightRule is set to "atLeast" and the row can have a greater height than the content.

So I think it'll be better to change the variable to a boolean exactHeight => true

[ivanlanin]

So the condition is like this, right?

• height set, hRule = auto
• height not set, hRule = atLeast (default) | exact

If so, I agree with you. It's easier to use boolean.

[jcarignan]

other way around!
height set, hRule = atLeast (default) | exact
height not set, hRule = auto

[ivanlanin]

Ups, my bad :) Are you going to re-push you commit? Can you sync yours with the current version of develop branch? You can find out how to do that in this manual. Tell me if you have any difficulties either in merging fork or creating unit tests.

[jcarignan]

just pushed another commit, new usage:
$table->addRow($height, array("exactHeight" => true));

I'll try to sync now (I'm using tortoise)

[ivanlanin]

Ok. Take your time. I'm off for a while.

[ivanlanin]

Merged with some modifications. I removed HTTP header from Word2007 writer class since PHPWord should also can be called from CLI.

Thank you @jcarignan.
