Search a word in a string using php function

When i search for "bank", it should display Bank-List1, Bank-List2 from the following list.

Railway-List, Bank-List1, Bank-List2, Education, Ecommerce, Articles, Railway-List1.

Is there is any php function to display?

I got the output for exact match. But no result for this type of search.

Please help me to find the solution.

This solution is only valid for this pattern of text is like: word1, word2, word3 

<?php
$text = 'Railway-List, Bank-List1, Bank-List2, Education, Ecommerce, Articles, Railway-List1.';


function search_in_text($word, $text){

 $parts = explode(", ", $text);
 $result = array();
 $word = strtolower($word);

 foreach($parts as $v){

  if(strpos(strtolower($v), $word) !== false){
   $result[] = $v;
  }

 }

 if(!empty($result)){
    return implode(", ", $result);
 }else{
    return "not found";
 }
}

echo search_in_text("bank", $text);
echo search_in_text("none", $text);
?>

output:

Bank-List1, Bank-List2
not found

You can do it using stristr. This function returns all of haystack starting from and including the first occurrence of needle to the end. Returns the matched sub-string. If needle is not found, returns FALSE.

Here is the complete code:

<?php

  $str="Railway-List, Bank-List1, Bank-List2, Education, Ecommerce, Articles, Railway-List1";
  $findme="bank";
  $tokens= explode(",", $str);
  for($i=0;$i<count($tokens);$i++)
  {
    $trimmed =trim($tokens[$i]);
    $pos = stristr($trimmed, $findme);
    if ($pos === false) {}
    else
    {
        echo $trimmed.",";
    }
  }
?>

you can use stristr

stristr — Case-insensitive strstr()

<?php    // Example from PHP.net
  $string = 'Hello World!';
  if(stristr($string, 'earth') === FALSE) {
    echo '"earth" not found in string';
  }
// outputs: "earth" not found in string
?>

So for your situation, if your list was in an array named $values

you could do

foreach($values as $value)
{
      if(stristr($value, 'bank') !== FALSE) 
      {
        echo $value."<br>";
      }
}
