Php replaces a string with an ellipsis (...).

Php replaces a string with an ellipsis (...).

This example describes how to replace the ellipsis (...) in the string with the intermediate character in php. Share it with you for your reference. The specific analysis is as follows:

For a long string, if you only want the user to see the content at the beginning and end and hide the intermediate content, you can use this php function to specify the number of intermediate strings to be hidden.

/** * Reduce a string by the middle, keeps whole words together * * @param string $string * @param int $max (default 50) * @param string $replacement (default [...]) * @return string * @author david at ethinkn dot com * @author loic at xhtml dot ne * @author arne dot hartherz at gmx dot net */function strMiddleReduceWordSensitive($string,$max=50,$rep='[...]'){  $strlen = strlen($string);  if ($strlen <= $max)    return $string;  $lengthtokeep = $max - strlen($rep);  $start = 0;  $end = 0;  if (($lengthtokeep % 2) == 0) {    $start = $lengthtokeep / 2;    $end = $start;  } else {    $start = intval($lengthtokeep / 2);    $end = $start + 1;  }  $i = $start;  $tmp_string = $string;  while ($i < $strlen) {    if (isset($tmp_string[$i]) and $tmp_string[$i] == ' ') {      $tmp_string = substr($tmp_string, 0, $i) . $rep;      $return = $tmp_string;    }    $i++;  }  $i = $end;  $tmp_string = strrev ($string);  while ($i < $strlen) {    if (isset($tmp_string[$i]) and $tmp_string[$i] == ' ') {      $tmp_string = substr($tmp_string, 0, $i);      $return .= strrev ($tmp_string);    }    $i++;  }  return $return;  return substr($string, 0, $start).$rep.substr($string, - $end);}

Demo:

// example:$text = 'This is a very long test sentence, bla foo bar nothing';print strMiddleReduceWordSensitive ($text, 30) . "\n";// Returns: This is a very[...]foo bar nothing (~ 30 chrs)print strMiddleReduceWordSensitive ($text, 30, '...') . "\n";// Returns: This is a very...foo bar nothing (~ 30 chrs)

I hope this article will help you with php programming.
