You can use strstr to do this.

echo strstr($str, 'www/audio');

Considering

$string="We have www/audio path where the audio files are stored";  //Considering the string like this

Either you can use

strstr($string, 'www/audio');

Or

$expStr=explode("www/audio",$string);
$resultString="www/audio".$expStr[1];

I use this functions

function strright($str, $separator) {
    if (intval($separator)) {
        return substr($str, -$separator);
    } elseif ($separator === 0) {
        return $str;
    } else {
        $strpos = strpos($str, $separator);

        if ($strpos === false) {
            return $str;
        } else {
            return substr($str, -$strpos + 1);
        }
    }
}

function strleft($str, $separator) {
    if (intval($separator)) {
        return substr($str, 0, $separator);
    } elseif ($separator === 0) {
        return $str;
    } else {
        $strpos = strpos($str, $separator);

        if ($strpos === false) {
            return $str;
        } else {
            return substr($str, 0, $strpos);
        }
    }
}

You can use substring and strpos to accomplish this goal.

You could also use a regular expression to pattern match only what you want. Your mileage may vary on which of these approaches makes more sense.

In this article, we will see how to remove special characters from strings in PHP, along with understanding their implementation through the examples. We have given a string and we need to remove special characters from string str in PHP, for this, we have the following methods in PHP:

Using str_replace() Method: The str_replace() methodis used to remove all the special characters from the given string str by replacing these characters with the white space (” “).

Syntax:

str_replace( $searchVal, $replaceVal, $subjectVal, $count )

Example: This example illustrates the use of the str_replace() function to remove the special characters from the string.

PHP

  function RemoveSpecialChar($str) {

      $res = str_replace( array( '\'', '"',

      ',' , ';', '<', '>' ), ' ', $str);

      return $res;

      }

  $str = "Example,to removeSpecial'Char;";

  $str1 = RemoveSpecialChar($str);

  echo $str1;

?>

Output:

Example to remove the Special Char

str_ireplace( $searchVal, $replaceVal, $subjectVal, $count )

Example to remove the Special Char

preg_replace( $pattern, $replacement, $subject, $limit, $count )
