= []Nota:
Prior to PHP 8.0.0, imagefttext() was an extended variant of imagettftext() which additionally supported the
options
. As of PHP 8.0.0, imagettftext() is an alias of imagefttext().
image
Una risorsa immagine, restituita da una delle funzioni di creazione immagine, come imagecreatetruecolor().
size
The font size to use in points.
angle
The angle in degrees, with 0 degrees being left-to-right reading text. Higher values represent a counter-clockwise rotation. For example, a value of 90 would result in bottom-to-top reading text.
x
The coordinates given by x
and
y
will define the basepoint of the first
character (roughly the lower-left corner of the character). This
is different from the imagestring(), where
x
and y
define the
upper-left corner of the first character. For example, "top left"
is 0, 0.
y
The y-ordinate. This sets the position of the fonts baseline, not the very bottom of the character.
color
The index of the desired color for the text, see imagecolorexact().
font_filename
The path to the TrueType font you wish to use.
Depending on which version of the GD library PHP is using, when
font_filename
does not begin with a leading
/
then .ttf
will be appended
to the filename and the library will attempt to search for that
filename along a library-defined font path.
In many cases where a font resides in the same directory as the script using it the following trick will alleviate any include problems.
<?php
// Set the environment variable for GD
putenv('GDFONTPATH=' . realpath('.'));
// Name the font to be used (note the lack of the .ttf extension)
$font = 'SomeFont';
?>
text
Text to be inserted into image.

Example #1 imagefttext() example
<?php
// Create a 300x100 image
$im = imagecreatetruecolor(300, 100);
$red = imagecolorallocate($im, 0xFF, 0x00, 0x00);
$black = imagecolorallocate($im, 0x00, 0x00, 0x00);
// Make the background red
imagefilledrectangle($im, 0, 0, 299, 99, $red);
// Path to our ttf font file
$font_file = './arial.ttf';
// Draw the text 'PHP Manual' using font size 13
imagefttext($im, 13, 0, 105, 55, $black, $font_file, 'PHP Manual');
// Output image to the browser
header('Content-Type: image/png');
imagepng($im);
?>
