Question

I have encountered an weird error in php today spend lots of hours but didn't got the reasons.

Here is the code

$query = "INSERT INTO `mobile_spacification` (`id`,`product_name`,`gsmarenaurl`, `network_technology`, `ntwrk_2gband`, `ntwrk_3gband`, `ntwrk_4gband`, `ntwrk_speed`, `ntwrk_gprs`, `ntwrk_edge`, `launch_anu`, `launch_status`, `body_diman`, `body_weight`, `body_sim`, `display_type`, `display_size`, `display_resolution`, `display_multitouch`, `display_protection`, `plateform_os`, `plateform_chipset`, `plateform_cpu`, `plateform_gpu`, `memory_crdslot`, `memory-internal`, `camera_primary`, `camera_feature`, `camera_video`, `cemara_secondary`, `sound_alert_type`, `sound_loudspeaker`, `audio_jack`, `comms_wlan`, `comms_bluetooth`, `comms_gps`, `comms_radio`, `comms_usb`, `feature_sensor`, `feature_messaing`, `feature_browser`, `featuer_java`, `feature_misc`, `battery_type`, `battery_stndby`, `battery_talktime`, `misc_color`)
                    VALUES 
             (NULL,'$name','$site','".$table_field['Technology']."','".$table_field['2G bands']."','".$table_field['3G bands']."','".$table_field['4G bands']."','".$table_field['Speed']."','".$table_field['GPRS']."','".$table_field['EDGE']."','".$table_field['Announced']."','".$table_field['Status']."','".$table_field['Dimensions']."','".$table_field['Weight']."','".$table_field['SIM']."','".$table_field['Type']."','".$table_field['Size']."','".$table_field['Resolution']."','".$table_field['Multitouch']."','".$table_field['Protection']."','".$table_field['OS']."','".$table_field['Chipset']."','".$table_field['CPU']."','".$table_field['GPU']."','".$table_field['Card slot']."','".$table_field['Internal']."',
             '".$table_field['Primary']."','".$table_field['Features']."','".$table_field['Video']."','".$table_field['Secondary']."','".$table_field['Alert types']."','".$table_field['Loudspeaker']."','".$table_field['3.5mm jack']."','".$table_field['WLAN']."','".$table_field['Bluetooth']."','".$table_field['GPS']."','".$table_field['Radio']."','".$table_field['USB']."','".$table_field['Sensors']."','".$table_field['Messaging']."','".$table_field['Browser']."','".$table_field['Java']."','".$table_field['Other Features']."','".$table_field['battery_type']."','".$table_field['Stand-by']."','".$table_field['Talk time']."','".$table_field['Colors']."');";


echo $query =  preg_replace( "/\r|\n/", "",htmlentities($query, ENT_QUOTES));               
$query_run = mysqli_query($conn,$query) or die("<br><br>".mysqli_error($conn));

It returns the following error

You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''Samsung Galaxy J3 (2016)','http://www.gsmarena.com/samsung_galax' at line 1

It's okay we got that kind of error when there is a syntax error so I did what I always do try echoing the query and copy pasting it to phpmyadmin sql

The echo says

when running this query in phpmyadmin I got no error it works fine but when running through php it returns error I am so confused....

Answer 1

您不能在整个查询字符串上使用htmlentities( ..., ENT_QUOTES )。

您看到了正确的查询，因为您的回显是由浏览器解析的，但如果您查看HTML源代码，您会看到如下内容：

(...) VALUES (NULL,&#039;Something&#039; (...)

删除ENT_QUOTES。

实际上，更好的做法是处理每个字段，而不是整个查询。最佳做法是使用准备好的陈述。
