# Tips-1) How to check if a string contain multiple specific words

substr_count() is counting for how many times the string appears, so when it's 0 then you know that it was not found. I would say this way is more readable than using str_pos()

If match some word in php

index.php
Example: PHP 
<?php
$data = "bangla";
if (strpos($data, 'bangla')!==false || strpos($data, 'english')!== false) {
    echo "Found";
} else {
    echo "Not Found";
}
?>

Output should be:

If match some word in php

PHP Match Specific Word

Here is a function that can perform this operation without using regular expressions which could be slower. Instead of passing a single string for the task, pass an array like
index.php
Example: PHP 
<?php
// function
function strposMultiple($haystack, $needle, $offset = 0) {
    if(is_string($needle))
        return strpos($haystack, $needle, $offset);
    else {
        $min = false;
        foreach($needle as $n) {
            $pos = strpos($haystack, $n, $offset);

            if($min === false || $pos < $min) {
                $min = $pos;
            }
        }

        return $min;
    }
}

// PHP Code for Result
$data = 'bad';
if (strposMultiple($data, ['bad', 'naughty']) !== false) {
  echo 'Matched';
} else {
    echo 'Not Matched';
}

?>

Output should be:

PHP Match Specific Word

If Match Some Word

For this, you will need Regular Expressions and the preg_match function. Something like:

index.php
Example: PHP 
<?php
$data = 'bad';
if(preg_match('(bad|naughty)', $data) === 1) 
{
echo 'Yes';    
} else {
echo 'No';    
}
?>

Output should be:

If Match Some Word

If Multiple Word Match

(preg_match return 1 if there is a match in the string, 0 otherwise).

multiple str_pos calls

index.php
Example: PHP 
<?php
$data = 'bad';
if (strpos($data, 'bad')!==false or strpos($data, 'naughty')!== false) {
    echo "Found";
} else {
    echo "Not Found";
}
?>

Output should be:

If Multiple Word Match

# Tips-2) How to extract words from Sentence in PHP

Extract Words like keywords from Sentence by PHP

PHP Function for extracting Words

Just use it in functional. Create a functions.php file and Insert following codes
functions.php
Example: PHP

// Extract Tag
function extractCommonWords($string){
      $stopWords = array('i','a','about','an','and','are','as','at','be','by','com','de','en','for','from','how','in','is','it','la','of','on','or','that','the','this','to','was','what','when','where','who','will','with','und','the','www');
   
      $string = preg_replace('/\s\s+/i', '', $string); // replace whitespace
      $string = trim($string); // trim the string
      $string = preg_replace('/[^a-zA-Z0-9 -]/', '', $string); // only take alphanumerical characters, but keep the spaces and dashes too…
      $string = strtolower($string); // make it lowercase
   
      preg_match_all('/\b.*?\b/i', $string, $matchWords);
      $matchWords = $matchWords[0];
      
      foreach ( $matchWords as $key=>$item ) {
          if ( $item == '' || in_array(strtolower($item), $stopWords) || strlen($item) <= 5 ) {
              unset($matchWords[$key]);
          }
      }   
      $wordCountArr = array();
      if ( is_array($matchWords) ) {
          foreach ( $matchWords as $key => $val ) {
              $val = strtolower($val);
              if ( isset($wordCountArr[$val]) ) {
                  $wordCountArr[$val]++;
              } else {
                  $wordCountArr[$val] = 1;
              }
          }
      }
      arsort($wordCountArr);
      $wordCountArr = array_slice($wordCountArr, 0, 10);
      return $wordCountArr;
}
?>

Here you can result out of texts from sentence

Just Copy and Paste following code to index.php Make a index.php file

index.php

<?php
include("functions.php");
$text = 'Cricket is the Most Popular Game in the World';

echo '<span class="badger badger-darkener"><a href="'.$url.'/browse/'.strtolower($catss).''.strtolower($k).'" style="color:blue;">#'.$k.'</a></span> ';
} 
?>

# Tips-12) How to get first 3 longest words from a sentence PHP

The solution would be like this:
  • Use explode() to get the words of the string in an array
  • "Partially" sort the array elements in descending order of length
  • Use a simple for loop to print the longest three words from the array.

So your code should be like this:

Method - 1

See the Example.

index.php
Example: PHP 
<?php
$text = 'one four eleven no upstairs';
$arr = explode(" ", $text);
$count = count($arr);
for($i=0; $i < $count; $i++){
    $max = $arr[$i];
    $index = $i;
    for($j = $i + 1; $j < $count; ++$j){
        if(strlen($arr[$j]) > strlen($max)){
            $max = $arr[$j];
            $index = $j;
        }
    }
    $tmp = $arr[$index];
    $arr[$index] = $arr[$i];
    $arr[$i] = $tmp;
    if($i == 3) break;
}

// print the longest three words
for($i=0; $i < 3; $i++){
    echo $arr[$i] . '<br />';
}
?>

Output should be:

Method - 2

Alternative method: (Using predefined functions)

index.php
Example: PHP 
<?php
$text = 'one four eleven no upstairs';
$arr = explode(" ", $text);
usort($arr,function($a, $b){
    return strlen($b)-strlen($a);
});
$longest_string_array = array_slice($arr, 0, 3);

// display $longest_string_array 
var_dump($longest_string_array);
?>

Output should be:

Method - 3

See my Example.

index.php
Example: PHP 
<?php
$text = 'one four eleven no upstairs';
$arr = explode(" ", $text);
$count = count($arr);
for($i=0; $i < $count; $i++){
    $max = $arr[$i];
    $index = $i;
    for($j = $i + 1; $j < $count; ++$j){
        if(strlen($arr[$j]) > strlen($max)){
            $max = $arr[$j];
            $index = $j;
        }
    }
    $tmp = $arr[$index];
    $arr[$index] = $arr[$i];
    $arr[$i] = $tmp;
    if($i == 3) break;
}

// print the longest three words
for($i=0; $i < 3; $i++){
    $long .= $arr[$i] . ' ';
}

echo $long;
?>

Output should be:

Method - 4

You need to create your own comparative function and pass it with array to usort php function. Ex.:

<?php
function lengthBaseSort($first, $second) {
    return strlen($first) > strlen($second) ? -1 : 1;
}

$text = 'one four eleven no upstairs';
$arr = explode(" ", $text);
usort($arr, 'lengthBaseSort');

var_dump(array_slice($arr, 0, 3));

It will output 3 longest words from your statement.

According to author changes:

If you have no ability to use usort for some reasons (may be for school more useful a recursive function) use following code:

<?php
$text = 'one four eleven no upstairs';
$arr = explode(" ", $text);

function findLongest($inputArray) {
    $currentIndex = 0;
    $currentMax = $inputArray[$currentIndex];
    foreach ($inputArray as $key => $value) {
        if(strlen($value) > strlen($currentMax)){
            $currentMax = $value;
            $currentIndex = $key;
         }
     }
     return [$currentIndex, $currentMax];
}

for($i = 0; $i < 3; $i++) {
    $result = findLongest($arr);
    unset($arr[$result[0]]);
    var_dump($result[1]);
}
?>

Output should be:

# Tips-14) How to remove all number from a string php

For Western Arabic numbers (0-9):

$words = preg_replace('/[0-9]+/', '', $words);

For all numerals including Western Arabic (e.g. Indian):

$words = '१३३७';
$words = preg_replace('/\d+/u', '', $words);
var_dump($words); // string(0) ""
  • \d+ matches multiple numerals.
  • The modifier /u enables unicode string treatment. This modifier is important, otherwise the numerals would not match.
