Php 检查尺寸、宽度和尺寸后上传图像；高度

我想在检查图像大小、宽度和高度后上载图像，但我的脚本有错误

代码：

<?php
  include('dbcon.php');
  $name=$_POST["name"];
  $tel=$_POST["tel"];

  //upload file syntax begining
  $fileField=$_FILES["fileField"]["name"];

  if($_FILES["fileField"]["size"] >= 50000) {
    echo "bigfile";
  }
  elseif {
    $fileField = @getimagesize($_FILES["fileField"]["tmp_name"]);
    ($fileField === FALSE || !($fileField[2] == IMAGETYPE_GIF || $fileField[2] == IMAGETYPE_JPEG || $fileField[2] == IMAGETYPE_PNG)); 
    echo "Only Allow jpeg,PNG,Gif";

  { 
  else{ 
    move_uploaded_file($_FILES["fileField"]["tmp_name"],"upload/".$_FILES["fileField"]["name"]);
    //upload file syntax ending
    $sql="insert into imgtb(name,tel,image)values('$name','$tel','$fileField')";
    $result=mysql_query($sql);
  }
?>

---

将代码更改为以下内容：

<?php
include('dbcon.php');
$name = $_POST["name"];
$tel = $_POST["tel"];

$fileField = $_FILES["fileField"]["name"];

if($_FILES["fileField"]["size"] >= 50000) {
    echo "big image";
} else {
    $fileField = @getimagesize($_FILES["fileField"]["tmp_name"]);
    if ($fileField === FALSE || !($fileField[2] == IMAGETYPE_GIF || $fileField[2] == IMAGETYPE_JPEG || $fileField[2] == IMAGETYPE_PNG)) {
        echo "Only Allow jpeg,PNG,Gif";
    } else {
        move_uploaded_file($_FILES["fileField"]["tmp_name"],"upload/".$_FILES["fileField"]["name"]);

        $sql="insert into imgtb(name,tel,image)values('$name','$tel','$fileField')";
        $result=mysql_query($sql);
    }
}
?>
