(PECL ps >= 1.1.0)
ps_set_text_pos — Sets position for text output
Описание
$psdoc
, float $x
, float $y
) : bool
Set the position for the next text output. You may alternatively set the x
and y value separately by calling ps_set_value() and
choosing textx respectively texty as
the value name.
If you want to output text at a certain position it is more convenient to use ps_show_xy() instead of setting the text position and calling ps_show().
