10 Amazing PHP snippets for your web application

Hello every one, welcome to my today’s post on PHP. In my last post We learned about on How to send various kinds of email using PHP. Today I’m going to share 10 amazing and awesome PHP snippets , that will help you for building next web application in efficient manner. Though PHP has it’s own rich library of functions but I’m trying to create my own functions and add them in my application.

Sometimes situation occurs and on that time we need to modify built-in functions according to our work requirements. I’d also faced a lot of difficult situation while developing software’s. From my modified code gallery, I love to share some of codes with you. They really worked and working so far for my self very well. I think they not only reduce your valuable times but also save your energy in software development session 🙂 So, Lets start….

1. Get Tomorrow Date:

function get_tomorrow_date() {
 $tomorrow = mktime(0,0,0,date("m"),date("d")+1,date("Y"));
 return date("Y-m-d", $tomorrow);
}

2. Get Today’s Date:

function get_today_date() {
 $today=date("Y-m-d");
 return today;
}

3. Get Last Day Date:

function get_last_date() {
 $tomorrow = mktime(0,0,0,date("m"),date("d")-1,date("Y"));
 return date("Y-m-d", $tomorrow);
}

4. Detect Local Host:

function is_localhost() {
  $localhost_ids = array('localhost', '127.0.0.1');
  if(in_array($_SERVER['HTTP_HOST'],$localhost_ids)){
    // not valid
    return 1;
  }
}

5. Get Day Name By Date:

function get_day_name_by_date($day,$month, $year) {

 $day_name = date("l", mktime(0,0,0,$month,$day,$year));
 return $day_name;

}

6. Print an array in nice way:

function debugPrint($object, $title = "", $isMarkup = false) {
  if( !empty($title)){
    echo "$title: ";
    }
  if( $isMarkup == false){
    echo " "; 
     print_r($object); 
  }
  else{
    echo htmlspecialchars($object);
  }
}

7. Get Month Name By Month Value:

function Month($NumMonth) {

   switch($NumMonth) {
      Case "01":
      return "January";
      break;

      Case "02":
      return "February";
      break;

      Case "03":
      return "March";
      break;

      Case "04":
      return "April";
      break;

      Case "05":
      return "May";
      break;

      Case "06":
      return "June";
      break;

      Case "07":
      return "July";
      break;

      Case "08":
      return "August";
      break;

      Case "09":
      return "September";
      break;

      Case "10":
      return "October";
      break;

      Case "11":
      return "November";
      break;

      Case "12":
      return "December";
      break;
    }

}

8. Replace/Remove Unwanted Texts/syntax from a string:

function setDescriptionString($inputString=""){ $replacedWords = array("…","‘","ó","<ul>","<li>","–","…"," ",""","&","“","”","<span>","</span>", "<p>","</p>", "/",":", "<", ">","<strong>", "</strong>", "<b>", "</b>", "<i>","</i>","span","strong","class","+","-","=","'","’"); $filteredString = str_replace($replacedWords, "", $inputString)."."; return $filteredString; }

9. Get Extension of a file/image:

function getExtension($str) {
    $i = strrpos($str,".");
    if (!$i) {
       return "";
    }
    $l = strlen($str) - $i;
    $ext = substr($str,$i+1,$l);
    return $ext;
}

10. Remove Spacial Characters from a string:

function removeSpacialCharacters($string="") {

   if (preg_match('/[^\w\d_ -]/si', $string)) {
     return preg_replace('/[^a-zA-Z0-9_ -]/s', '', $string);
   } else {
     return preg_replace('/\s/', ' ', $string);
     }
   }
