deib97 Posted January 30, 2019 Share Posted January 30, 2019 I was hard code to make if condition until like seem. But its to hard to write. if ($lebar == 41) { $x = 1; } else if ($lebar == 42) { $x = 2; } else if ($lebar == 43) { $x = 3; } else if ($lebar == 44) { $x = 4; } else if ($lebar == 45) { $x = 5; ..... } else if ($lebar == 490) { $x = 450; } How to make it simple with looping or any clue?

Most people think programming is a matter of learning syntax and design patterns and APIs and technical stuff. Truth is, sometimes it's just a matter of using common sense.

ginerjm Posted January 30, 2019 Share Posted January 30, 2019 What is "hehe"? Are you joking with us? You've been given a hint as to how to solve it. Twice I believe. How about: $x = $lebar - 40; And yes - you do need $ signs on all of your variables. Come on!

deib97 Posted January 31, 2019 Author Share Posted January 31, 2019 Sorry if my question and my approach made you angry. I am making a calculator application to calculate tank volume and weight in kilograms(with Specific Gravity). This tank is shaped like a tube and cone in the excel table that I attached (there is a picture). In my application there is an input field for entering the sounding level data. and count button. If the level is <40 cm, the volume formula uses (0.33 * 3.14 * jari* jari * height / 1000) but if the level of souding shows a level> 40 cm, the volume formula is different. Details can be seen in the excel data that I attached. I do not want to create an atmosphere of misunderstanding,I just want to get help if that is possible. If not, it's okay. I attach an link excel file, the application display file as a simulation of what I mean. my excel. Look at column S to AE.

ginerjm Posted January 31, 2019 Share Posted January 31, 2019 I may be missing something but I'll submit this: $x = $lebar - 40; at whatever point in your code you need to make this calculation for the value of $x.

Yes, Barand. I do not allow entering input height many times. One time gives the number height on the stick level. I agree with you about cone height 40cm. Formulas cone + cylinder if height stick from manhole is open and > 40cm.

Barand Posted February 1, 2019 Share Posted February 1, 2019 In the absence of a reply, I estimated the radius to be about 3.5m from that photo. This gives a table of volmes and weights based on that radius. Note the absence of if..., if..., if..., if...) <?php const R = 350; // radius of tank cm NOTE: estimated - replace with actual radius const HC = 40; // cone height cm function tank_volume ($h) { $k = M_PI * R**2 ; if ($h <= HC) { $vol = $k * $h / 3 ; } else { $vol = $k * HC / 3 + $k * ($h - HC); } return $vol; } $results = []; foreach (range(1,500) as $h) { $vol = tank_volume($h); $results[] = [ 'ht' => $h, 'vol' => number_format($vol, 0), 'Kg' => number_format($vol/1000, 0) ]; } $chunks = array_chunk($results,100); $output = ''; foreach ($chunks as $ch) { $output .= "<div class='output'> <table><tr><th>Height<?th><th>Volume (cc)</th><th>Kg</th></tr> "; foreach ($ch as $res) { $cls = $res['ht'] < 41 ?
