The IntlChar tolower() function converts the character into Unicode character lowercase.SyntaxIntlChar::tolower (val)Parametersval − An integer or character encoded as a UTF-8 string.ReturnThe IntlChar tolower() function returns the converted lowercas character. If the character is already in lowercase, the same character is returned.ExampleThe following is an example −OutputThe following is the output −string(1) "J" NULL string(1) "J" NULL

The IntlChar toupper()function converts the character into Unicode character uppercase.SyntaxIntlChar::toupper (val)Parametersval − An integer or character encoded as a UTF-8 string.ReturnThe IntlChar toupper()function returns the converted uppercase character. If the character is already in uppercase, the same character is returned.ExampleThe following is an example −OutputThe following is the output −string(1) "J" NULL string(1) "J" NULL

The imagecreate() function is used to create a new image. It is preferred to use imagecreatetruecolor() to create an image instead of imagecreate(). This is because the image processing occurs on the highest quality image possible which can be created using imagecreatetruecolor().Syntaximagecreate( $width, $height )Parameterswidth: The width of imageheight: The height of imageReturnThe imagecreate() function returns an image resource identifier on success or FALSE on errors.ExampleThe following is an example:OutputThe following is the output:

The imagesx() function gets the width of image. It returns the width of the image or FALSE on errors.Syntaximagesx(img)Parametersimg: Image resource created with imagecreatetruecolor()ReturnThe imagesx() function returns the width of the image or FALSE on errors.ExampleThe following is an example: Live DemoOutputThe following is the output:450

The imagesy() function gets the height of image. It returns the height of the image or FALSE on errors.Syntaximagesy(img)Parametersimg: Image resource created with imagecreatetruecolor()ReturnThe imagesy() function returns the height of the image or FALSE on errors.ExampleThe following is an example: Live DemoOutputThe following is the output:250

The imagecolorat() function gets the index of the color of the pixel.Syntaximagecolorat( $img, $x, $y )Parametersimg: Create an image with imagecreatetruecolor() function.x: The x-coordinate of the point.y: The y-coordinate of the point.ReturnThe imagecolorat() function returns the color index or FALSE on failure.ExampleThe following is an example: Live DemoOutputThe following is the output:array(4) { ["red"]=> int(255) ["green"]=> int(255) ["blue"]=> int(255) ["alpha"]=> int(127) }

The getimagesize() function is used to display the size of an image.Syntaxgetimagesize(file_name, img_info)Parametersfile_name: The file image i.e. the image path.img_info: Extract some extended information from the image file. Supports only JFIF files.ReturnThe getimagesize() function returns an array element with height, width, type, MIME type of the image, etc.ExampleThe following is an example: Live DemoOutputThe following is the output:Array ( [0] => 205 [1] => 120 [2] => 3 [3] => width="205" height="120" [bits] => 8 [mime] => image/png)

The imagefill() function is used to fill the image.Syntaximagefill(img, x, y, color)ParametersimgCreate a blank image with imagecreatetruecolor().x x-coordinate of start pointy y-coordinate of start pointcolor The fill color.ReturnThe imagefill() function returns TRUE on success or FALSE on failure.ExampleThe following is an example:OutputThe following is the output:
