I want to sort an array which will always contain three objects.  The script knows the name values of the objects that should be returned second and third.  How can I sort this array so that the order is correct?  $categories = Array (   [48] =&gt; stdClass Object (      [term_id] =&gt; 48      [name] =&gt; Hello      [term_group] =&gt; 0      [term_taxonomy_id] =&gt; 57      [taxonomy] =&gt; resume_category      [description] =&gt;      [parent] =&gt; 0      [count] =&gt; 572      [object_id] =&gt; 18397      [filter] =&gt; raw   )   [64] =&gt; stdClass Object (       [term_id] =&gt; 64      [name] =&gt; World      [term_group] =&gt; 0      [term_taxonomy_id] =&gt; 75      [taxonomy] =&gt; resume_category      [description] =&gt;      [parent] =&gt; 0      [count] =&gt; 22      [object_id] =&gt; 18397      [filter] =&gt; raw  )  [5] =&gt; stdClass Object (      [term_id] =&gt; 5      [name] =&gt; Test      [term_group] =&gt; 0      [term_taxonomy_id] =&gt; 75      [taxonomy] =&gt; resume_category      [description] =&gt;      [parent] =&gt; 0      [count] =&gt; 22      [object_id] =&gt; 5      [filter] =&gt; raw    )   I want Hello as the second value and World as the last value but the values and order of the array are dynamic and will vary:     foreach ( $categories as $category ) {     echo $category-&gt;name;     echo ', ';    }   Should return: test, hello, world
Basically I have a setup like the following:  Array (  [0] =&gt; Array ( [0] =&gt; stdClass Object ( [nid] =&gt; 1 [title] =&gt; title1 [uid] =&gt; 1 [parent] =&gt; 0 [weight] =&gt; -15 [name] =&gt; name1 [value] =&gt; 0 )                [1] =&gt; stdClass Object ( [nid] =&gt; 2 [title] =&gt; title2 [uid] =&gt; 1 [parent] =&gt; 0 [weight] =&gt; -7 [name] =&gt; name2 [value] =&gt; 100 )                [2] =&gt; stdClass Object ( [nid] =&gt; 3 [title] =&gt; title3 [uid] =&gt; 2 [parent] =&gt; 0 [weight] =&gt; -1 [name] =&gt; name3 [value] =&gt; 0 )                [3] =&gt; stdClass Object ( [nid] =&gt; 4 [title] =&gt; title4 [uid] =&gt; 2 [parent] =&gt; 0 [weight] =&gt; 1 [name] =&gt; name4 [value] =&gt; 80 )               )   )   What I need is a way to sort all the arrays inside the parent array by the [value] key in the Object. I've been trying for about 2 days now with usort and different methods but I just can't seem to get my head around it. The [value] key will range anywhere from 0 to 100 and I need all of the arrays sorted in decreasing order (IE: 100 down to 0).
Can I install any iOS version I wish by picking and choosing which firmware to restore? I'm trying to downgrade my iPhone from the current iOS to an older one, as per .  But every time I try, I always receive this error:     The iPhone could not be restored. This device isn't eligible for the requested build.     I have tried many times with and without DFU mode. Any ideas regarding this? fontenc changes sans serif bold font in KOMA-script Consider the following MWE:  \documentclass{article} %\usepackage[T1]{fontenc}  \begin{document}  \textbf{\textsf{Some text}}  \end{document}   The output of the above code is     and doesn't change if I uncomment the line  %\usepackage[T1]{fontenc}   Consider now the following MWE with scrartcl class instead of article:  \documentclass{scrartcl} %\usepackage[T1]{fontenc}  \begin{document}  \section{A section} \textsf{Some text} \end{document}      Uncommenting the line  %\usepackage[T1]{fontenc}   you get    As you can see, the sans serif font of the title is less  bold than without fontenc, while the normal text is not changed.  Does fontenc, combined with a KOMA-script class, load a different sans serif font, but only for bold face? I am searching for [free] software that can produce nice looking graphical models, e.g.     Any suggestions would be appreciated. Is the "live" in "He only lived a few days after the accident" intrasitive or transitive? close votes vs votes remaining I am new to the review part of Stack Overflow and I am trying to understand what is the meaning of votes remaining in the Review | Close Vote.  For example: Today I was at my 39 vote and it said that there was still 21 votes remaining.        However, after my 40 vote:        So, apparently I have started with 60 votes but I can use only 40? Does "corresponding author" carry an implied meaning? After reading the question , I got the impression that (at least in the writers' field) the "corresponding author" flag could carry an implied meaning, such as "did more work than the other authors", or "is a more senior author". Is it the case?  I am in mathematics, a field where we typically sort the authors alphabetically, and I've never given any importance to that role (apart from "this author is willing to answer a couple of extra e-mails, if needed"). Apparently, my linux ubuntu setup of QGIS doesn't contain grass gis, although when I initially installed it last week I added grass gis to the command line. Anyway, I typed in once again and installed grass gis 7.0, however while GRASS starts, the plugin QGIS for it doesn't show up. Any ideas? How does a cell phone charger work? I have studied that there is a transformer which steps down the ac voltage after then bridge rectifier to convert into ac to dc and then given to filter, this is what I have learnt in books, but when I open a mobile charger I couldn't figure it out how it actually works? I have two different list. In the first list are some people picker columns.  Is it possible to create a lookup column for list 2 to add the user from the first list? I know it isn't supported in Sharepoint, but i hope someone have an idea to solve my problem. I know that a continuous function which is a BV may not be absolutely continuous.  Is there an example of such a function?   I was looking for a BV whose derivative is not Lebesgue integrable but I couldn't find one.

Repeating something with (1/n)th chance of success n times I am trying to ask a question on SE, have some mock data in Excel I've copied, and am simply trying to paste in to my question.  I've done this before dozens of times, but suddenly am having this issue.  However, when I do so, I get prompted to upload an image. (This happens with Ctrl + V and also right click --> Paste):    Am I overlooking something?  Edit: Playing around, I can copy from Firefox/browsers and Word, and paste in to the box as usual. Excel seems to be the only one giving the issue so far.  Edit2:  are still having this issue. How do I calculate the date six months from the current date using the datetime Python module? My random variable $X$ is normally distributed with mean $b$ and variance $p$. I defined a new RV, $Y$, such that $Y=1/X$. Does anyone know how to find the mean of $Y$ and $Y^2$? My /boot partition hit 100% and now I can't upgrade. Can't remove old kernels to make room My first issue was when I tried to apt-get update or apt-get upgrade.

Try 'apt-get -f install' with no packages (or specify a solution).   How can I free up or extend boot without messing up my installation? Does $\lim_{n\to \infty} \int^{\infty}_{-\infty} f_n(x) dx\, = \int^{\infty}_{-\infty} f(x)\,dx\,$? If $\displaystyle\{f_n(x)\}$ is sequence of continuous function on $\mathbb{R}$ converging uniformly to $f(x)$, then does $\displaystyle\lim_{n\to \infty} \int^{\infty}_{-\infty} f_n(x) dx\, = \int^{\infty}_{-\infty} f(x) dx\,$ hold? I know  it holds if we integrate over an interval of the form $[a,b]$ but not sure about improper integral! Get three highest values from the array Splicing a list of arguments into a function with Sequence Are Groups or Sketchup-like components feasible in Blender? Apart from testing it myself, I've seen a few posts  and , including from Sketchup users like me, sort of circle around this topic but never ask this question directly. How can I overcome these problems in DupliGroups or Collection Instances?  moving its origin seems to require moving to World origin (and using up a layer for clarity) &lt;=&gt; linked meshes have their own local origin which I can move data around in Edit Mode (easy enough)  It is impractical to link up DupliGroup data to previously created meshes because the origin mismatch as above, and the mesh data that remains in it and needs to be deleted somehow  Linked meshes don't have the above two problems (can be 'blocked in' and then detailed up all at once) but I can't add objects to them, only faces. Say I'd like to add handles as linked meshes, because handles are used elsewhere in the model too.    How feasible would it be to make a linked object type with deeper hierarchy? Say an object that would look at its children and simply make every other instance have the same children. It would also mean dragging and dropping in outliner would be the simplest way to manage it by the looks of it.
