Search a word in a string using php function

Question

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.

Answer 1

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>";
      }
}

Answer 2

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.",";
    }
  }
?>
