PHP remove all characters before specific string

Question

I need to remove all characters from any string before the occurrence of this inside the string:

\"www/audio\"

Not sure how I can do this.<

Answer 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);
        }
    }
}

Answer 2

You can use strstr to do this.

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

Answer 3

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];

Answer 4

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.
