I want to modify an array cell, which I can do when I know the cell as a number. However here my cell position is given by $i.
pomme[`${i}`]=""
I tried without the `` and it doesn't work either?
How am I suppose to do it?
Having two arrays in variable php
php,mysql,arrays,variables,multidimensional-array
The explode function is being used correctly, so your problem is further up. Either $data[$i] = mysql_result($result,$i,"data"); isn't returning the expected string "2015-06-04" from the database OR your function $data[$i] = data_eng_to_it_($data[$i]); isn't returning the expected string "04 June 2015" So test further up by echo / var_dump after both...

Vagrant doesn't inherently support this, since it's intended audience is really development environments. It seems like you're looking for something more like what VMWare vSphere does.
Bash modify CSV to change a field
Please save following awk script as awk.src: function date_str(val) { Y = substr(val,0,4); M = substr(val,5,2); D = substr(val,7,2); date = sprintf("%s-%s-%s",Y,M,D); return date; } function time_str(val) { h = substr(val,9,2); m = substr(val,11,2); s = substr(val,13,2); time = sprintf("%s:%s:%s",h,m,s); return time; } BEGIN { FS="|" } # ## MAIN...
Comparing arrays with numbers in vb.net
There are a few basic ways of checking for a value in an integer array. The first is to manually search by looping through each value in the array, which may be what you want if you need to do complicated comparisons. Second is the .Contains() method. It is simpler...
Array JLabel ActionListener multiple JPanels
You cannot directly add an ActionListener to a JLabel - it doesn't have that functionality. Instead, you should create a MouseAdapter, override the mouseClicked method, and use JLabel.addMouseListener to add it to your JLabels. The best way to get it to, as you say, "display a panel and the other...
Javascript function to validate contents of an array
You can use a simple array based test like var validCodes = ['IT00', 'O144', '6A1L', '4243', 'O3D5', '44SG', 'CE64', '54FS', '4422']; function validItems(items) { for (var i = 0; i < items.length; i++) { if (validCodes.indexOf(items[i]) == -1) { return items[i]; } } return ''; } var items = ["IT00",...
jQuery - Value in Function
You need to use brackets notation to access property by variable: function myFunc( array, fieldToCompare, valueToCompare ) { if( array[fieldToCompare] == "Thiago" ) alert(true); } And wrap name in quotes: myFunc( myArray, 'name', "Thiago" ); ...

Delete some lines from text using Linux command
linux,shell,sed,grep,pattern-matching
The -v option to grep inverts the search, reporting only the lines that don't match the pattern. Since you know how to use grep to find the lines to be deleted, using grep -v and the same pattern will give you all the lines to be kept. You can write...
C++ & Qt: Random string from an array area
You should use the random header. #include <random> std::default_random_engine generator; std::uniform_int_distribution dist(0, 5); int StringIndex = dist(generator); std::string ChosenString = characters[StringIndex]; The above will generate a random index into your array. If you want to limit the range, change the constructor of dist, for example (dist(0,2) would only allow for...
Notice: Array to string conversion in “path of php file” on line 64

ret_from_syscall source code and when it is called
linux,linux-kernel,kernel,linux-device-driver,system-calls
The ret_from_syscall symbol will be in architecture-specific assembly code (it does not exist for all architectures). I would look in arch/XXX/kernel/entry.S. It's not actually a function. It is part of the assembly code that handles the transition from user-space into kernel-space for a system call. It's simply a label to...
Translating a character array into a integer string in C++
If you want a sequence of int, then use a vector<int>. Using the key_char string, the values of the chars in it will serve as the initial value of the ints. std::vector<int> key_num(key_char.begin(), key_char.end()); Then, iterate over each character of key_num and convert it to the equivalent int value for...
most efficient way to create javascript array out of various php arrays
John, Try this: var dataSet = []; for (i = 0; i < mfrPartNumber.length; i++ ) { data = [dateReceived[i],name[i],color[i]]; dataSet.push(data); } This will build an array out of each instance of [i], and keep growing as your user keeps pushing the button....
Infinite loop with fread
If you're "trying to allocate an array 64 bytes in size", you may consider uint8_t Buffer[64]; instead of uint8_t *Buffer[64]; (the latter is an array of 64 pointers to byte) After doing this, you will have no need in malloc as your structure with a 64 bytes array inside is...

array and function php
$x and $y are only defined within the scope of the function. The code outside of the function does not know what $x or $y are and therefore will not print them. Simply declare them outside of the function as well, like so: <?php function sum($x, $y) { $z =...
How to check if data already exists then randomly generate new data from an Array
In my personal opinion, NEVER try to get data from an array within quotes! Always do it outside of quotes; especially in multi-denominational arrays. '$input[$rand_keys[$i]]' should be rewritten as '".$input[$rand_keys[$i]]."' OR '{$input[$rand_keys[$i]]}'. In my opinion it is better to do it outside of quotes instead of using { }. ...

accessing range of values in arduino array
Arrays in C++ don't allow this syntax. What you should do is something like this: char[2] id; if( sx1272.packet_received.length > 5 ) { id[0] = sx1272.packet_received.data[4]; id[1] = sx1272.packet_received.data[5]; } ...

While loop in bash using variable from txt file
As indicated in the comments, you need to provide "something" to your while loop. The while construct is written in a way that will execute with a condition; if a file is given, it will proceed until the read exhausts. #!/bin/bash file=Sheetone.txt while IFS= read -r line do echo sh...
How to pass array in rails 4 strong parameters

The valid range of indices of an array with N elements is [0, N-1]. Thus instead of for example this loop for (int i=1; i <= n; i++) ^^^^ ^^^^^^ you have to write for ( int i = 0; i < n; i++ ) As you used operator new...

Perl: Using Text::CSV to print AoH
Pretty fundamentally - CSV is an array based data structure - it's a vaguely enhanced version of join. But the thing you need for this job is print_hr from Text::CSV. First you need to set your header order: $csv->column_names (@names); # Set column names for getline_hr () Then you can...
Segmentation Fault if I don't say int i=0
c,arrays,segmentation-fault,initialization,int
In your code, int i is an automatic local variable. If not initialized explicitly, the value held by that variable in indeterministic. So, without explicit initialization, using (reading the value of ) i in any form, like array[i] invokes undefined behaviour, the side-effect being a segmentation fault. Isn't it automatically...
How to pivot array into another array in Ruby

NASM: copying a pointer from a register to a buffer in .data
The problem is, you don't have debug info for the ptr type, so gdb treats it as integer. You can examine its real contents using: (gdb) x/a &ptr 0x600124 <ptr>: 0x7fffffffe950 (gdb) p/a $rsp $3 = 0x7fffffffe950 Of course I have a different value for rsp than you, but you...

How do I print more than one value per key in Tcl?
You can't do it with arrays or dictionaries; both are mappings from keys to values. Instead, you need to use foreach with a key-value pair system directly: set pairs { set1 table set2 chair set1 chair } foreach {key value} $pairs { puts "$key is $value" } This does actually...
