stream_socket_client - Open Internet or Unix domain socket connection

resource stream_socket_client ( string $remote_socket [, int &$errno [, string &$errstr [, float $timeout = ini_get("default_socket_timeout") [, int $flags = STREAM_CLIENT_CONNECT [, resource $context ]]]]] )

Open Internet or Unix domain socket connection

Initiates a stream or datagram connection to the destination specified by remote_socket. The type of socket created is determined by the transport specified using standard URL formatting: transport://target. For Internet Domain sockets (AF_INET) such as T


<?php

imagecopyresampled-Copy and resize part of an image with resampling

bool imagecopyresampled ( resource $dst_image , resource $src_image , int $dst_x , int $dst_y , int $src_x , int $src_y , int $dst_w , int $dst_h , int $src_w , int $src_h )

Copy and resize part of an image with resampling

imagecopyresampled() copies a rectangular portion of one image to another image, smoothly interpolating pixel values so that, in particular, reducing the size of an image still retains a great deal of clarity.


<?php// The file
$filename = 'test.jpg';
$percent = 0.5;// Content type
header('Content-Type: image/jpeg');// Get new dimensions
list($width, $height) = getimagesize($filename);$new_width = $width * $percent;$new_height = $height * $percent;// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);// Output
imagejpeg($image_p, null, 100);?>
