PHP Practical code fragment must be collected _php tips

It's always good to have a magic tool when writing code! Here's a collection of 40+ PHP snippets that can help you develop PHP projects. We have already shared the 23 PHP code snippets that must be collected.
These PHP snippets are also very helpful to PHP beginners, very easy to learn, let's start to learn it ~

24. Create a CSV file from PHP data

function Generatecsv ($data, $delimiter = ', ', $enclosure = ' "') {
  $handle = fopen (' php://temp ', ' r+ ');
  foreach ($data as $line) {
      fputcsv ($handle, $line, $delimiter, $enclosure);
  Rewind ($handle);
  while (!feof ($handle)) {
      $contents. = Fread ($handle, 8192);
  }
  Fclose ($handle);
  return $contents;
}
  

Grammar:

<?php
$data [0] = "apple";
$data [1] = "oranges";
Generatecsv ($data, $delimiter = ', ', $enclosure = ' ");
? >

25. Parsing XML Data

$xml _string= "<?xml version= ' 1.0 '?>
<moleculedb>
  <molecule name= ' benzine ' >
    < symbol>ben</symbol>
    <code>A</code>
  </molecule>
  <molecule name= ' Water ' >
    <symbol>h2o</symbol>
    <code>K</code>
  </molecule>
</ Moleculedb> ";
   
The load the XML string using SimpleXML function
$xml = simplexml_load_string ($xml _string);
   
Loop through the each node of molecule
foreach ($xml->molecule as $record)
{
  //attribute are accesste D
  by Echo $record [' name '], ';
  Node are accessted by-> operator
  Echo $record->symbol, ';
  echo $record->code, ';
}

26. Parse JSON Data

$json _string= ' {"id": 1, "name": "Rolf", "Country": "Russia", "office": ["Google", "Oracle"]} ';
$obj =json_decode ($json _string);
Print the parsed data
echo $obj->name;//displays Rolf
echo $obj->office[0];//displays Google

27. Get the current page URL
This PHP fragment can help you get the user to log in and jump directly to the previous page

function Current_url ()
{
$url = "http://". $_server[' http_host '. $_server[' Request_uri '];
$validURL = Str_replace ("&", "&", $url);
return validurl;
}

Grammar:

<?php
echo "Currently you are on:". Current_url ();
? >

28. Get the latest tweets from any Twitter account

function My_twitter ($username)
{
   $no _of_tweets = 1;
   $feed = "Http://search.twitter.com/search.atom?q=from:". $username. "&rpp=". $no _of_tweets;
   $xml = Simplexml_load_file ($feed);
  foreach ($xml->children () as $child) {
    foreach ($child as $value) {
      if ($value->getname () = = "link") $link = $ value[' href '];
      if ($value->getname () = "Content") {
        $content = $value. "";
    Echo ' <p class= ' twit > '. $content. ' <a class= ' TWT ' href= '. $link. ' title= ' "> </a></p> ';
      }  
    }
  }  
}  

Grammar:

$handle = "Koonktech";
My_twitter ($handle);
? >

29. Forwarding Quantity
Use this PHP fragment to detect how many forwarding numbers your page URLs have

  $element = new SimpleXMLElement ($content);
  $retweets = $element->story->url_count;
  if ($retweets) {return
    $retweets;}
  else {return
    0;
}}

$date 2 = "2015-12-04";
$diff = ABS (Strtotime ($date 2)-Strtotime ($date 1));
$years = Floor ($diff/(365*60*60*24));
$months = Floor (($diff-$years * 365*60*60*24)/(30*60*60*24));
$days = Floor (($diff-$years * 365*60*60*24-$months *30*60*60*24)/(60*60*24));
printf ("%d years,%d months,%d days\n", $years, $months, $days);
--------------------------------------------------------OR $date 1 = new DateTime ("2007-03-24");
$date 2 = new DateTime ("2009-06-26");
$interval = $date 1->diff ($date 2); echo "Difference". $interval->y. "Years," he said.
$interval->m. "Months," $interval->d. "Days"; Shows the total amount of days (not divided to years, months and days like above) echo "difference". $interval->days.
