Enum (kinda)

class ItemTypeEnum
{
    const Document = 0;
    const Book= 1;
    const Image= 2;
    const Photo= 3;
    const Article=4;

}

PDF Page Count

Opt1 (Debunked for PDF's with more that 160~ pages)

$file = $pdfFile->openFile()->fread($pdfFile->getSize());
$pageCount = preg_match_all("/\/Page\W/", $file, $dummy);*/

Opt2

//https://github.com/howtomakeaturn/pdfinfo
//pdfinfo has to be installed in system
composer require "howtomakeaturn/pdfinfo:1.*"

$pdf = new PDFInfo('path/to/the/pdf');
//or just file itself $pdf = new PDFInfo($request->file('uploadedFileFromForm'));
echo $pdf->title; // Get the title
echo $pdf->pages; // Get the number of pages

Lazy Clever programmers alphabet

$alphabet=range('A', 'Z');

Order in Alphabet

function orderInAlphabet($letter){
 return ord(strtoupper($letter)) - ord('A') + 1;
}

ASCII value of a char

ord("a");
//uppercase differs!

Iterate array (don't use this)

//8 times slower than foreach, don't use this
$test = array_fill(0, 10000, 'test_data');
array_walk($test, function($value, $index)
{
    $value = 'testdata';
});
//foreach equivalent
foreach ($test as $key => $value)
{
    $result[$key] = 'testdata';
}

Array push

//is the arr first or second param ? lulz
//this is the reason i miss prototype functions, extensions 
array_push($arr, "apple");

Array to string

$comma_separated = implode(",", $array);

Split a string into an array (by delimeter)

$pieces = explode(" ", $pizza);

Uniques of an array

$unique = array_unique($arr); 
//this messes up the indexes, so maybe use it like this

$unique = array_values(array_unique($arr)); 
//basically array_values just changes indexes to numeric and order based.

Amount of duplication for each duplicate in an array

count duplicate amounts

$counts=array_count_values($arr)

//Example var_dump($counts)
/*
array(8) {
  [20]=>
  int(2)
  [1]=>
  int(2)
  [-1]=>
  int(2)
  [2]=>
  int(2)
  [-2]=>
  int(2)
  [3]=>
  int(2)
  [5]=>
  int(3)
  [4]=>
  int(2)
}
//Means 5 as value has occured 3 times in the array.
*/

Get array elements starting with 'foo'

$hasParameters= array_filter($arr, function ($key) {
            return strpos($key, 'foo-') === 0;
        }, ARRAY_FILTER_USE_KEY);
