How can I remove duplicate arrays? it's different from array unique because that is removing duplicate values inside array..  i get an array list like this  1. array('item' =&gt; 6, 'quantity' =&gt; 1, 'price' =&gt; 120) 2. array('item' =&gt; 6, 'quantity' =&gt; 1, 'price' =&gt; 120) 3. array('item' =&gt; 6, 'quantity' =&gt; 1, 'price' =&gt; 120) 4. array('item' =&gt; 22, 'quantity' =&gt; 8, 'price' =&gt; 30) 5. array('item' =&gt; 22, 'quantity' =&gt; 8, 'price' =&gt; 30)   how do i make like this while keeping the values?  3. array('item' =&gt; 6, 'quantity' =&gt; 1, 'price' =&gt; 120) 4. array('item' =&gt; 22, 'quantity' =&gt; 8, 'price' =&gt; 30)     code  $get = file_get_contents('URL');     $json = json_decode($get, true);     $results = print_r($json);     file_put_contents('file.json', print_r($json, true), FILE_APPEND);
How can I remove duplicate values from a multi-dimensional array in PHP?  Example array:  Array (     [0] =&gt; Array     (         [0] =&gt; abc         [1] =&gt; def     )      [1] =&gt; Array     (         [0] =&gt; ghi         [1] =&gt; jkl     )      [2] =&gt; Array     (         [0] =&gt; mno         [1] =&gt; pql     )      [3] =&gt; Array     (         [0] =&gt; abc         [1] =&gt; def     )      [4] =&gt; Array     (         [0] =&gt; ghi         [1] =&gt; jkl     )      [5] =&gt; Array     (         [0] =&gt; mno         [1] =&gt; pql     )  )
Django template how to look up a dictionary value with a variable How can I save the command and its execution output to file at the same time Suppose I have a command java -cp src/ nlp.lm.BigramModel wsj/ 0.1, I want to save the command itself and the command execution output to the file at the same time.  One way to do this is to   echo "$ java -cp src/ nlp.lm.BigramModel atis/ 0.1" &gt; trace/bigram-trace.txt     java -cp src/ nlp.lm.BigramModel atis/ 0.1 &gt;&gt; trace/bigram-trace.txt   Is there a better way to do this? Problem on Extremal Graphs: three independent paths The problem states that:     A simple (or strict) graph with $n$ vertices and $m&gt;\dfrac{3(n-1)}{2}$ edges, has two vertex   joined by three independent paths.   Any hints, ideas or useful results, to attack this problem? Its very easy to prove $p\mid n^p-n$ for p=3,5,7, it fails for p=9 because $$     (n+1)^9-(n+1)= n^9+9n^8+36n^7+84n^6+126n^5+126n^4+84      n^3+36n^2+8n $$ and $84= 2²\times 3\times7$. Is it true for any $p$ prime? I have checked many primes, but have no idea for the general case. I have long been confused about this notion. I know that for a statement within a single category, forming the dual statement is just reversing every arrows. But what about a statement concerning several categories and functors between them?   Mac Lane suggests reversing all arrows in all categories and leaving the functors invariant in his book "Categories for the working mathematician" (page 32), but it seems that Mac Lane himself doesn't always follow this discipline (when he states "the dual of Yoneda Theorem", he doesn't reverse the arrows in $\mathbf{Set}$ !) Can anyone give me a formal definition of "dualize a statement in category theory"? Hiding winforms app from taskbar Password hash function for Excel VBA Array versus List: When to use which? Interpretation of R's lm() output How do we know the brain flips images projected on the retina back around? Splitting raster into smaller chunks using GDAL? I have a raster (USGS DEM actually) and I need to split it up into smaller chunks like the image below shows. That was accomplished in ArcGIS 10.0 using the Split Raster tool. I would like a FOSS method to do this. I've looked at GDAL, thinking surely it would do it (somehow with gdal_translate), but can't find anything. Ultimately, I'd like to be able to take the raster and say how large (4KM by 4KM chunks) I would like it split up into. How to create and animate the water reflection (Caustics) on an object?

HTML escapes appearing in node titles on bespoke content type — substitutions? Generate three correlated uniformly-distributed random variables What is meant by a "random variable"? I happen, time and again, to read and hear people – among which people working in cinema – regretting the fact that film (in the sense of actual reels of plastic strip) is nowadays very rarely used when shooting movies. Is there some ground to such nostalgia?  Of course I am not looking for opinions for or against film vs. digital media, but sourced, objective reasons. Is there anything that could be done with film but not with digital supports? Are there measurable differences in effects on viewers? Can Dropbox be used with multiple accounts on one computer? Is "gift" accepted as a verb? I have always argued adamantly, as long as the issue has been around, that gift should never be used as a verb. However, someone whose English knowledge I quite respect disagrees.  I’ve done some searching and I haven’t found a consensus; should gifting be shunned? If $f_n$ converges to $f$ in $L^1$ and $g_n$ converges to $g$ in $L^1$. Does it necessarily mean that $f_ng_n$ converges to $fg$ in $L^1$ for finite measure spaces.
