To keep the forums high quality for all users, please take the time to format your posts correctly.
First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)
Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.
Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Hi,
I couldn't figure how to extract until last occurence of a character.

The output should be /dir1/file1
So, the command should display the path until last occurence of "/".
Thanks. (3 Replies)

imagecolortransparent
IMAGECOLORTRANSPARENT(3) 1 IMAGECOLORTRANSPARENT(3)imagecolortransparent - Define a color as transparentSYNOPSIS
int imagecolortransparent (resource $image, [int $color])
DESCRIPTION
Sets the transparent color in the given $image.
PARAMETERS
o $
image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).
o $color
- A color identifier created with imagecolorallocate(3).
RETURN VALUES
The identifier of the new (or current, if none is specified) transparent color is returned. If $color is not specified, and the image has
no transparent color, the returned identifier will be -1.
EXAMPLES
Example #1
imagecolortransparent(3) example
<?php
// Create a 55x30 image
$im = imagecreatetruecolor(55, 30);
$red = imagecolorallocate($im, 255, 0, 0);
$black = imagecolorallocate($im, 0, 0, 0);
// Make the background transparent
imagecolortransparent($im, $black);
// Draw a red rectangle
imagefilledrectangle($im, 4, 4, 50, 25, $red);
// Save the image
imagepng($im, './imagecolortransparent.png');
imagedestroy($im);
?>
The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : imagecolortransparent()
NOTES
Note
Transparency is copied only with imagecopymerge(3) and true color images, not with imagecopy(3) or pallete images.
Note
The transparent color is a property of the image, transparency is not a property of the color. Once you have set a color to be the
transparent color, any regions of the image in that color that were drawn previously will be transparent.
