How can we get the properties (size, type, width, height) of
an image using PHP image functions?
Answer Posted / kartihk
getimagesize ( string filename [, array imageinfo])
Returns an array with 4 elements.
Index 0 contains the width of the image in pixels.
Index 1 contains the height.
Index 2 a flag indicating the type of the image. 1 = GIF, 2
= JPG, 3 = PNG, 4 = SWF, 5 = PSD, 6 = BMP, 7 = TIFF(intel
byte order), 8 = TIFF(motorola byte order, 9 = JPC, 10 =
JP2, 11 = JPX.
Index 3 is a text string with the correct height="yyy"
width="xxx" string that can be used directly in an IMG tag.
<?php
$imgp = getimagesize ("img/flag.jpg");
echo "<img src=\"img/flag.jpg\" {$imgp[3]}>";
?>
