Resize final image before display - php

Question

I've created a PHP script to generate an avatar. When I display the image, the dimensions are 250px x 250px. I want to resize at the end (when all the modifications has been done) the avatar before displaying it but I can not find the function.
This is my code :
if(!empty($_GET['pseudo']))
{
$query1 = $bdd->prepare("SELECT username, user_id, VID FROM phpbb_users LEFT JOIN 0php_users ON 0php_users.phpbb_id = phpbb_users.user_id WHERE username_clean = ?");
$query1->execute(array(strtolower($_GET['pseudo'])));
if($query1->rowCount() == 1)
{
$data1 = $query1->fetch();
$query2 = $bdd->prepare("SELECT nom FROM phpbb_user_group
RIGHT JOIN 0php_hubs ON phpbb_user_group.group_id = 0php_hubs.id_groupe
WHERE user_id = ?");
$query2->execute(array($data1['user_id']));
$data2 = $query2->fetch();
$image = imagecreatefrompng("avatar.png");
$background = imagecolorallocate($image, 0, 0, 0);
imagecolortransparent($image, $background);
imagealphablending($image, false);
imagesavealpha($image, true);
if(($_GET['param']=='ivao')&&(!empty($data1['VID'])))
{
$BoolIvao = true;
$ivao = imagecreatefrompng("http://status.ivao.aero/R/".$data1['VID'].".png");
imagecopy($image, $ivao, 87, 173, 0, 0, 150, 30);
}
$couleur = imagecolorallocate($image, 0, 0, 0);
$largeur_source = imagesx($image);
$fontfile = 'calibri.ttf';
$angle = 0;
$police = 18;
$text_size = imagettfbbox($police, $angle, $fontfile, 'Hub de '.$data2['nom']);
$text_size2 = imagettfbbox($police, $angle, $fontfile, $data1['username']);
$text_width = (($text_size[2] + $text_size[4]) / 2) - (($text_size[0] + $text_size[6]) / 2);
$text_width2 = (($text_size2[2] + $text_size2[4]) / 2) - (($text_size2[0] + $text_size2[6]) / 2);
$x = ($largeur_source - $text_width)/2;
$x2 = (176 - $text_width2)/2 + 74;
$y2 = ($BoolIvao == true)?160:175;
imagettftext($image, $police, $angle, $x2, $y2, $couleur, $fontfile, $data1['username']);
imagettftext($image, $police, $angle, $x, 35, $couleur, $fontfile, 'Hub de '.$data2['nom']);
imagepng($image);
$query2->closeCursor();
}
$query1->closeCursor();
}
Thanks

You need to use imagecopyresampled to resize image.
<?php
if(!empty($_GET['pseudo']))
{
$query1 = $bdd->prepare("SELECT username, user_id, VID FROM phpbb_users LEFT JOIN 0php_users ON 0php_users.phpbb_id = phpbb_users.user_id WHERE username_clean = ?");
$query1->execute(array(strtolower($_GET['pseudo'])));
if($query1->rowCount() == 1)
{
$data1 = $query1->fetch();
$query2 = $bdd->prepare("SELECT nom FROM phpbb_user_group
RIGHT JOIN 0php_hubs ON phpbb_user_group.group_id = 0php_hubs.id_groupe
WHERE user_id = ?");
$query2->execute(array($data1['user_id']));
$data2 = $query2->fetch();
$image = imagecreatefrompng("avatar.png");
list($width, $height) = getimagesize("avatar.png"); # get dimensions
$background = imagecolorallocate($image, 0, 0, 0);
imagecolortransparent($image, $background);
imagealphablending($image, false);
imagesavealpha($image, true);
if(($_GET['param']=='ivao')&&(!empty($data1['VID'])))
{
$BoolIvao = true;
$ivao = imagecreatefrompng("http://status.ivao.aero/R/".$data1['VID'].".png");
imagecopy($image, $ivao, 87, 173, 0, 0, 150, 30);
}
$couleur = imagecolorallocate($image, 0, 0, 0);
$largeur_source = imagesx($image);
$fontfile = 'calibri.ttf';
$angle = 0;
$police = 18;
$text_size = imagettfbbox($police, $angle, $fontfile, 'Hub de '.$data2['nom']);
$text_size2 = imagettfbbox($police, $angle, $fontfile, $data1['username']);
$text_width = (($text_size[2] + $text_size[4]) / 2) - (($text_size[0] + $text_size[6]) / 2);
$text_width2 = (($text_size2[2] + $text_size2[4]) / 2) - (($text_size2[0] + $text_size2[6]) / 2);
$x = ($largeur_source - $text_width)/2;
$x2 = (176 - $text_width2)/2 + 74;
$y2 = ($BoolIvao == true)?160:175;
imagettftext($image, $police, $angle, $x2, $y2, $couleur, $fontfile, $data1['username']);
imagettftext($image, $police, $angle, $x, 35, $couleur, $fontfile, 'Hub de '.$data2['nom']);
/* resize image */
$small_im = imagecreatetruecolor(250, 250);
imagecopyresampled($small_im, $image, 0, 0, 0, 0, 250, 250, $width, $height);
/* resize image */
imagepng($small_im);
$query2->closeCursor();
}
$query1->closeCursor();
}

this is the code I always use to resize an image through PHP (I hope it will help you) best wishes:
NOTE: $filetemp refers to your file's temporary name.
Also in this code i'm saving images as a png you can change it to your desired extension
<?php
$temporary = pathinfo($filename, PATHINFO_FILENAME);
$new_images = $temporary.".png";
$width=60; //*** Fix Width & Heigh (Autu caculate) ***//
$size=GetimageSize($filetemp);
$height=round($width*$size[1]/$size[0]);
$images_orig = ImageCreateFromJPEG($filetemp);
$photoX = ImagesX($images_orig);
$photoY = ImagesY($images_orig);
$images_fin = ImageCreateTrueColor($width, $height);
ImageCopyResampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY);
imagepng($images_fin,"YourFolder/".$new_images);
ImageDestroy($images_orig);
ImageDestroy($images_fin);
?>
