您错过了查询部分之间的空白。 改变
$query = $select.$from.$where;
到
$query = $select." ".$from." ".$where;
此外,您应该在每个sql语句后检查错误。
答案 1 :(得分:0)
您收到此错误是因为您的查询返回了错误结果。
$ from =“FROM jobs.id”;
我认为您的表名是作业,因此请将其替换为作业并使用以下方法检查结果:
如果(!空($结果)){
}

<?php
function db_connection(){
$connection = mysqli_connect("localhost","slenderman","slenderman");
if(!$connection){
return false;
}
if(!mysqli_select_db($connection,"joblicious")){
return false;
}
return $connection;
}
function find_jobs(){
db_connection();
$select = ("SELECT jobs.id,
jobs.location,
jobs.title,
jobs.company,
jobs.description,
jobs.url ");
$from = ("FROM jobs");
$where = ("WHERE jobs.id >0");
$query = $select." ".$from." ".$where;
$result = mysqli_query(db_connection(),$query);
while($row = mysqli_fetch_array($result)){
echo $row["title"];
}
}
find_jobs();
?>

不鼓励您编写SQL查询的方式。尝试整体编写查询:
$query = "SELECT jobs.id, jobs.location, jobs.title, jobs.company, jobs.description, jobs.url FROM jobs.id WHERE jobs.id >0";
我确定由于select
语句的语法不正确而导致此错误(很可能是由于缺少空格)。
请查看 PHP 的syntax manual,以避免将来出现此类错误。
