• Add 'x' 30 mins blocks to time string (javascript)

  - by Mikey1980

  I have a 24 hour time string (ie 16:30) and would like to add x time blocks of 30 mins. For example if x = 4, then 16:30 + 4(30) = 18:30. Is there any easy way to do this with out exploding the string and doing if statements for mins/hours.. etc? Also this is on a php page would it be easier to do this in php then echo it to the javascript? Thanks for the help!

  - by niggles

  If I have this array: $foo[0] = 'bar'; $foo[1] = 'bar bar'; echo $foo[0][1]; // result a // i.e the second letter of 'bar' I want to check that $foo[0][1] is not set i.e if I had: $foo[0][1] = 'bar'; it would evaluate to true, but in my original example of $foo[0] = 'bar' I would expect that: isset($foo[0][1]) would return false; What's the correct way to test that please.

• Unexpected variable update when using bash's $(( )) operator for arithmetic

  - by philo

  I'm trying to trim a few lines from a file. I know exactly how many lines to remove (say, 2 from the top), but not how many total lines are in the file. So I tried this straightforward solution: $ wc -l $FILENAME 119559 my_filename.txt $ LINES=$(wc -l $FILENAME | awk '{print $1}') $ tail -n $(($LINES - 2)) $FILENAME > $OUTPUT_FILE The output is fine, but what happened to LINES?? $ wc -l $OUTPUT_FILE 119557 my_output_file.txt $ echo $LINES 107 Hoping someone can help me understand what's going on.

• PHP something faster than explode to get filename from URL

  - by FFish

  My URL's can be absolute or relative: $rel = "date/album/001.jpg"; $abs = "http://www.site.com/date/album/image.jpg"; function getFilename($url) { $imgName = explode("/", $url); $imgName = $imgName[count($imgName) - 1]; echo $imgName; } There must be a faster way to do this right? Maybe a reg expression? But that's Chinese to me..

• Problem with pointers and getstring function

  - by volting

  I am trying to write a function to get a string from the uart1. Its for an embedded system so I don't want to use malloc. The pointer that is passed to the getstring function seems to point to garbage after the gets_e_uart1() is called. I don't use pointers too often so I'm sure it is something really stupid and trivial that Im doing wrong. Regards, V int main() { char *ptr = 0; while(1) { gets_e_uart1(ptr, 100); puts_uart1(ptr); } return 0; }*end main*/ //------------------------------------------------------------------------- //gets a string and echos it //returns 0 if there is no error char getstring_e_uart1(char *stringPtr_, const int SIZE_) { char buffer_[SIZE_]; stringPtr_ = buffer_; int start_ = 0, end_ = SIZE_ - 1; char errorflag = 0; /*keep geting chars until newline char recieved*/ while((buffer_[start_++] = getchar_uart1())!= 0x0D) { putchar_uart1(buffer_[start_]);//echo it /*check for end of buffer wraparound if neccesary*/ if(start_ == end_) { start_ = 0; errorflag = 1; } } putchar_uart1('\n'); putchar_uart1('\r'); /*check for end of buffer wraparound if neccesary*/ if(start_ == end_) { buffer_[0] = '\0'; errorflag = 1; } else { buffer_[start_++] = '\0'; } return errorflag; } Update: I decided to go with approach of passing a pointer an array to the function. This works nicely, thanks to everyone for the informative answers. Updated Code: //------------------------------------------------------------------------- //argument 1 should be a pointer to an array, //and the second argument should be the size of the array //gets a string and echos it //returns 0 if there is no error char getstring_e_uart1(char *stringPtr_, const int SIZE_) { char *startPtr_ = stringPtr_; char *endPtr_ = startPtr_ + (SIZE_ - 1); char errorflag = 0; /*keep geting chars until newline char recieved*/ while((*stringPtr_ = getchar_uart1())!= 0x0D) { putchar_uart1(*stringPtr_);//echo it stringPtr_++; /*check for end of buffer wraparound if neccesary*/ if(stringPtr_ == endPtr_) { stringPtr_ = startPtr_; errorflag = 1; } } putchar_uart1('\n'); putchar_uart1('\r'); /*check for end of buffer wraparound if neccesary*/ if(stringPtr_ == endPtr_) { stringPtr_ = startPtr_; *stringPtr_ = '\0'; errorflag = 1; } else { *stringPtr_ = '\0'; } return errorflag; }

  Would what mentioned in the title be possible? Python module style that is. See this example for what I exactly mean. index.php <?php use Hello\World; World::greet(); Hello/World.php <?php namespace Hello\World; function greet() { echo 'Hello, World!'; } Would this be possible?

• turn array into object active record can use

  - by stormdrain

  I'm running a query and then decrypting it in the controller. After it is decrypted I was putting the results into an array and sending that to the view. The problem is with this solution I need to rewrite all of my views to parse the arrays sent instead of the active record objects sent before. Is there a way to turn the decrypted array back into an object that will work with existing active record code in the view? Before Controller: $name = $this->Clients_model->getNameData('*','client_id='.$clid,''); $data['name'] = $name; $this->load->view('names/name_view',$data); View: if($name->num_rows()) > 0){ foreach($name->result() as $row){ echo $row->data; [...] Now Controller: $name = $this->Clients_model->getNameData('*','client_id='.$clid,''); $nameArray= array(); foreach ($name->result() as $row){ $x = $row; $keys = array('id','client_id'); $unenc = array(); foreach ($x as $key=>$value){ if(! in_array($key, $keys)){ $unenc[$key]=$this->encrypt->decode($value,$this->e_key); }else{ $unenc[$key]=$value; } } array_push($nameArray,$unenc); } //Creates an object with the data, but doesn't work with CI active record //foreach ($nameArray as $akey => $aval) { // $namea -> {$akey} = $aval; //} //return $data; $data['name'] = $nameArray; $this->load->view('names/name_view',$data); View: if(count($name) > 0){ foreach($name as $key=>$row){ echo $row['data']; [...] In the second (now) controller there is some commented out code that will make an object, but it doesn't behave as expected with active record. Is there a way to take the $nameArray() array and change it into an object that will work with existing view code (such as the code in the 'before:view' above)? Thanks!
