Image Question

How do I put two images side by side in php?

I know I can use <img src=""> but I want to make two images into one.

If anyone could help that would be great!

 

This sounds like a job for gd....

Check out http://www.php.net/manual/en/function.imagecopymerge.php

 

Because I felt like doing it...


This merges images horizontally. There might be a code on php.net for this (I didn't check), but I felt like writing my own.

function imagemergefiles(array $image_sources)
{
	$widths = array();
	$heights = array();
	
	// Get image sizes
	foreach ($image_sources AS $source)
	{
		if (!list($widths[], $heights[]) = @getimagesize($source))
		{
			trigger_error(__FUNCTION__ . "(): Unable to create image from {$source}", E_USER_WARNING);
			return false;
		}
	}
	
	if (!$widths OR !$heights)
	{
		trigger_error(__FUNCTION__ . '(): No valid images found', E_USER_WARNING);
		return false;
	}
	
	// Create blank image with the dimensions we need
	$img = imagecreatetruecolor(array_sum($widths), max($heights));
	$posx = 0;
	
	// Walk through all images and merge them horizontally
	foreach ($image_sources AS $key => $image)
	{
		if (!$tmp_image = imagecreatefrom_autodetect($image))
		{
			trigger_error(__FUNCTION__ . "(): Unable to create image from {$image}", E_USER_WARNING);
			return false;
		}

		imagecopymerge($img, $tmp_image, $posx, 0, 0, 0, $widths[$key], $heights[$key], 100);
		$posx += $widths[$key];
		unset($tmp_image); // Save some memory
	}
	
	return $img;
}


function imagecreatefrom_autodetect($source)
{
	if (($type = strtolower(end(explode('.', $source)))) == 'jpg')
	{
		$type = 'jpeg';
	}
	
	if (!function_exists($function = "imagecreatefrom{$type}"))
	{
		trigger_error(__FUNCTION__ . "(): Unsupported image type {$type}", E_USER_WARNING);
		return false;
	}
	
	return $function($source);
}

PHP:

Usage example:

<?php

$images = array(
    'image1.jpg',
    'image2.jpg',
    'image3.jpg'
);

$image = imagemergefiles($images);

header('Content-Type: image/jpeg');
imagejpeg($image);

?>

You're welcome.

 

You can get rid of the whole imagecreatefrom_autodetect() thing and just use imagecreatefromstring().
