php - stristr find exact string

I have the following string:

P90 | Ash Wood (Well-Worn)

I'm passing this through the following:

$item = str_replace("|","", $item);
$item = str_replace(" (","-",$item);
$item = str_replace(")","",$item);
$item = str_replace(" ","-",$item);
$item = str_replace("--","-",$item);
$item = str_replace("™","",$item);
$item = str_replace("★-","",$item);
$item = str_replace("★","",$item);

Which returns:

P90-ASH-WOOD-WELL-WORN

I'm now comparing this string against a file of strings to find a match:

$lines = file(public_path().'/csgoanalyst.txt');
foreach ($lines as $line) {
    // Check if the line contains the string we're looking for, and print if it does
    if (stristr($line, $item)) {  // case insensitive
         echo $line;
         break;
    }
}

The problem I have is the file contains the follownig:

http://csgo.steamanalyst.com/id/2018/SOUVENIR-P90-ASH-WOOD-WELL-WORN
http://csgo.steamanalyst.com/id/919/P90-ASH-WOOD-WELL-WORN

both lines contain matches therefor are both valid, however I'm looking for an exact match - in this case the second URL.

Try Using preg_match as 

$lines = file(public_path().'/csgoanalyst.txt');
foreach ($lines as $line) {
    // Check if the line contains the string we're looking for, and print if it does
    if(preg_match('/(?<!\-)(P90\-ASH\-WOOD\-WELL\-WORN)\b/',$line)) {  // case insensitive
         echo $line;
         break;
    }
}

I tried this ...

 <?php
        $item = "P90-ASH-WOOD-WELL-WORN";
        $lines = array(
            "http://csgo.steamanalyst.com/id/2018/SOUVENIR-P90-ASH-WOOD-WELL-WORN",
            "http://csgo.steamanalyst.com/id/919/P90-ASH-WOOD-WELL-WORN-TEST",
            "http://csgo.steamanalyst.com/id/919/P90-ASH-WOOD-TEST-WELL-WORN",
            "http://csgo.steamanalyst.com/id/919/P90-ASH-WOOD-WELL-WORN"
        );

        foreach ($lines as $line) {

            echo "checking: ".$line."<br/>";

        // Check if the line contains the string we're looking for ...
            if (stristr($line, $item)) {  // case insensitive
                $line_as_array = explode('/', $line);
                if (end($line_as_array) === $item) { // check two string are same
                    echo "matched: ".$line."<br/>";
                    break;
                }
            }
        }
        ?>

and found the result as ...

checking: http://csgo.steamanalyst.com/id/2018/SOUVENIR-P90-ASH-WOOD-WELL-WORN
checking: http://csgo.steamanalyst.com/id/919/P90-ASH-WOOD-WELL-WORN-TEST
checking: http://csgo.steamanalyst.com/id/919/P90-ASH-WOOD-TEST-WELL-WORN
checking: http://csgo.steamanalyst.com/id/919/P90-ASH-WOOD-WELL-WORN
matched: http://csgo.steamanalyst.com/id/919/P90-ASH-WOOD-WELL-WORN

seems working ...

My answer is to use end to only grab the last part of the explode'd string and then preg_match it with ^ and $ to signify beginning and end of the string you want to match. So anything with something on the front or the end will not match. Only exact matches will work.

<?
$item = "P90-ASH-WOOD-WELL-WORN";
$list = array("http://csgo.steamanalyst.com/id/2018/SOUVENIR-P90-ASH-WOOD-WELL-WORN","http://csgo.steamanalyst.com/id/919/P90-ASH-WOOD-WELL-WORN");

foreach ($list as $line)
{
    if (preg_match("/^$item$/",end(explode("/",$line))))
    {
        echo $line;
        break;
    }
}
?>

the result:

Add this small code

  • exploding line with '/' into array.

  • access last value of array with end().

  • comparing this to item variable then printing if matched. 

      foreach ($lines as $line) {
  // Check if the line contains the string we're looking for, and print    if it does
    if (stristr($line, $item)) {  // case insensitive
      $lineArr = explode('/', $line);
      if(end($lineArr) == $item)
      {
        echo $line;
        break;
      }
    }
 }
