this will help I have a string array with string elements, here how to check each string element at the end contains carriage return(\n, \r, \n\r) and add if not contains at the end. , Its pretty simple to do:
code :
var arr = new string[5];
for(int i =0; i< arr.Length; i++)
    if (!arr[i].EndsWith("\r") && !arr[i].EndsWith("\n"))
        arr[i] = $"{arr[i]}\r\n";

Check if array element exists in string

I wish this helpful for you I thought this would be a simple thing to do with a native php function but i've found a few different, all quite complicated, ways that people have tried to achieve it. What's the most efficient way of checking if a string contains one or more elements in an array? i.e, below - where $data['description'] is a string. Obv the in_array check below breaks because it expects param 2 to be an array , Assuming that the String is a collapsed/delimited list of values
code :
function arrayInString( $inArray , $inString , $inDelim=',' ){
  $inStringAsArray = explode( $inDelim , $inString );
  return ( count( array_intersect( $inArray , $inStringAsArray ) )>0 );
}
arrayInString( array( 'red' , 'blue' ) , 'red,white,orange' , ',' );
// Would return true
// When 'red,white,orange' are split by ',',
// the 'red' element matched the array
arrayInString( array( 'mouse' , 'cat' ) , 'mouse' );
// Would return true
// When 'mouse' is split by ',' (the default deliminator),
// the 'mouse' element matches the array which contains only 'mouse'
function arrayInString( $inArray , $inString ){
  if( is_array( $inArray ) ){
    foreach( $inArray as $e ){
      if( strpos( $inString , $e )!==false )
        return true;
    }
    return false;
  }else{
    return ( strpos( $inString , $inArray )!==false );
  }
}
arrayInString( array( 'apple' , 'banana' ) , 'I ate an apple' );
// Would return true
// As 'I ate an apple' contains 'apple'
arrayInString( array( 'car' , 'bus' ) , 'I was busy' );
// Would return true
// As 'bus' is present in the string, even though it is part of 'busy'

Most efficient way to check if array element exists in string

may help you . I've been looking for a way to check if any of an array of values exists in a string, but it seems that PHP has no native way of doing this, so I've come up with the below. , Try with following function:
code :
function contains($input, array $referers)
{
    foreach($referers as $referer) {
        if (stripos($input,$referer) !== false) {
            return true;
        }
    }
    return false;
}

if ( contains($referer, $valid_referers) ) {
  // contains
}

In perl, how can I pattern match a string to see if a carriage return exists in a line

wish of those help If you are interested in a quick fix, you might look into the dos2unix utility. In Perl, you could do
code :
perl -pi -le 's/[\r\n]+\z//' yourfile.txt

Check if an element exists in a 2d array and return something if true

help you fix your problem I'm not all that familiar with using multidimensional arrays and here I'm trying to see if an element exists in a 2d array and if it does, I want some sort of indication. , A control flag will be useful:
code :
bool found = false;
for (unsigned int row = 0; (!found) && (row < MAX_ROWS); ++ row)
{
  for (unsigned int column = 0; (!found) && (column < MAX_COLUMNS); ++ column)
  {
    if (matrix[row][column] == search_value)
    {
       found = true;
    }
  }
}
bool found = false;
for (unsigned int row = 0; (!found) && (row < MAX_ROWS); ++ row)
{
  for (unsigned int column = 0; (!found) && (column < MAX_COLUMNS); ++ column)
  {
    if (matrix[row][column] == search_value)
    {
       found = true;
       break;
    }
  }
  if (found)
  {
    break;
  }
}

I wish this help you getline won't read the newline. However, in this case it's relatively simple to work around this problem.
Where you currently have linecount++;, add these lines before it:
