How do I download a filled-out php form?
It doesn't sound like you understand how PHP handles forms. The usual scenario is you present the user with an HTML page that contains the form. The action attribute of the opening form tag indicates the webpage that will process the submitted form (and confirm to the user that it has done so). The form-processing page will contain PHP code to do what you need to do with the contents of the form. For example, it will usually store the information in a server-side database, like MySQL. It might also send an email to someone.If you want to provide the user with a downloadable, editable form, you could do that by having PHP create a PDF with the submitted data I can't imagine why you'd want to do that, but it's possible.
How many 8cm spheres does it take to fill 1500 gallons?
It does depend somewhat on the shape of the 1500 gallon container.Roughly, though there are 3785.41 cm^3 / gallon.An 8 centimeter diameter sphere has approximate volume 268 cm^3, from 4/3 pi r^3.But a search reveals that “For equal spheres in three dimensions the densest packing uses approximately 74% of the volume. A random packing of equal spheres generally has a density around 64%.”Thus, for random packing, the effective volume of one of the spheres is 268 cm^3 * (1.0 / 0.64). Call this SV for the effective volume of one sphere.Then the number that will fit in the volume is given by:1500 gallons * 3785.41 cm^3 / gallons * (1 sphere / SV cm^3) = number of spheresNote that all the units except “spheres” cancel, giving confidence in the formula.I assume that you can do the arithmetic. Also, the answer should be good to only 2 significant digits.
How can I create an online certificate for membership? I want to send a link for members to just fill out and download.

You can ask for information such as name and/or email and additional ‘extra information’ questions that you can choose to make mandatory. If you like, you can choose to include these on the certificates as well.You will also be able to choose what your users see when they have finished completing their questionnaire. You can choose to not show any questions and answers but instead some customized feedback to thank your users for taking the time to fill out your questionnaire and any additional details you require, along with redirecting them elsewhere.Users will then click on the ‘certificate download’ button on their results page on-screen and/or have the results emailed to them which will also include the certificate download link so that they can download their certificate at a time that is convenient for them!You had mentioned you want to send a link to members - you can do this in ClassMarker by assigning your questionnaire to a link, in which you can then embed this directly into a page on your website or email them the link.You can check out ClassMarker’s video demo here:Online Testing Video Demonstrations
