Hi there,
I've hit a bit of a roadblock on something I've been working on, was wondering if anyone knew of a way to fix the error message:
imagecreatefromjpeg():php_network_getaddresses: getaddrinfo failed
The code I'm using is below, the script basically grabs a certain image from a set of specific urls and resizes it as close to 600x450 as it can, then saves the image/images in a zip file which the user can then download.
I should also mention that I'm currently hosting this on x10hosting, and it runs a-okay locally.
<?php
include 'zip.php';
function getImage($tags){
$count = 0;
foreach ($tags as $tag){
$tag->getAttribute('src');
$count += 1;
if ($count == 3){
$old_image = $tag->getAttribute('src');
return $old_image;
}
}
}
function deleteFiles($random_name){
$images= scandir("$random_name"); //get an array of files
unset($images[0], $images[1]);
// loop through files
foreach($images as $image){
unlink("$random_name/$image"); // delete each file
}
rmdir($random_name);
}
$omitted_urls = [];
if (isset($_POST['submit'])){
$start_time = time();
$urls = $_POST['urls']; // take inputted urls
$urls = explode("\r\n", $urls); // break them up by a carriage return/new line into array
$names = $_POST['names']; // take inputted names
$names = explode("\r\n", $names); // break them up by a carriage return/new line into array
$random_name = "pics".rand(0,1000); // create a random folder name
if (!is_dir("$random_name")){
mkdir("$random_name", 0777);
}
// for each url
for($i=0; $i < count($urls); $i++){
@$html = file_get_contents($urls[$i]); // get the contents of the url
$doc = new DOMDocument();
@$doc->loadHTML($html); // load up the html file
$tags = $doc->getElementsByTagName('img'); // look for all img tags
$count = 0;
$special_chars = array('\\','/',':','*','?','"','<','>','|'); // look for any special characters
$names[$i] = str_replace($special_chars, "", $names[$i]); // replace them with ""
$names[$i] = substr($names[$i], 0, 50); // truncate anything over 50 characters
if($old_image = imagecreatefromjpeg(getImage($tags))){ // create the old image
echo "The src is ".getImage($tags)."<br>";
$old_width = imagesx($old_image); // get the width of the old image
$old_height = imagesy($old_image); // get the height of the old image
$ratio_orig = $old_width/$old_height; // work out the ratio of the image
$new_width = 600; $new_height = 450;
if ($new_width/$new_height > $ratio_orig){
$new_width = $new_height*$ratio_orig;
} else {
$new_height = $new_width/$ratio_orig;
}
$new_image = imagecreatetruecolor($new_width, $new_height); // creates a black image to represent size
imagecopyresampled($new_image, $old_image, 0, 0, 0, 0, $new_width, $new_height, $old_width, $old_height); // copy over old image to fit new image
imagejpeg($new_image, "$random_name/".$names[$i].'.jpg'); // create the new image file
imagedestroy($new_image); // destroy the image file
$time = time()- 3600; // find out the time
} else {
$omitted_urls[] = $names[$i];
}
}
$final_time = time() - $start_time; // final time is the current time take the starting time
$final_time = date("i:s", $final_time); // time taken
}
