Replace space with _
Extension method to test whether a string is null or empty or whitespace
public static bool IsNullOrEmpty(this string input)
{
if (string.IsNullOrEmpty(input))
return true;
return string.IsNullOrEmpty(input.Trim());
}
Remove leading whitespace from a text file
$ cat file.txt | sed -e 's/^[ ]*//'
Converts big whitespaces into one whitespace
<?php
$string = 'This string has no whitespaces.';
echo ereg_replace( ' +', '', $string ); //note: before '+' we have 2 spaces
?>
Output: This string has no white spaces.
// OR EVEN BETTER
trim's code can of course be simplified with some use of the trim() function....
<?php
$str = " Words with lots of spaces ";
$str = preg_replace('/ss+/', ' ', trim($str));
?>
Doing the trim() first reduces the workload being put on the more expensive preg_replace().
