A php website that has a search function. I'm now trying to add a link to a mysql database search rather than just showing the results. In my search.php, the echo line is working fine but the $string .= is not returning anything. I'm just trying to get the same as the echo but with the link to the mysql php record.

问题 I'm looking to maximise the number of stars given a certain budget and max limit on the combination...

问题 hey how can i search for a file in HDD , example i wanna search for a file settings.ini in my computer . 回答1: First you have to get a list of valid drives. This was discussed previously on the StackOverflow. The you have to call FindFirst/FindNext/FindClose on the root folder of each drive. Get a list of files and directories. Check the list of files. Repeat this for each directory. Until you run out of directories. Search for "[delphi] findfirst" on StackOverflow to find more information.

问题 I've been through many tutorials on how to create the search filter but I can't get any of them to work. I think usually encounter a problem because many of the tutorials I have found use a String but I use my custom class. How would you make the search filter for a custom class and adapter? Here's my MainActivity code package com.example.android.college3; import android.content.Intent; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.View; import
