String Manipulation in PHP

I've got a string in php it can be in one of two formats - either:

"example1" AND somethingelse = "exa开发者_开发问答mple2"

or just

"example1"

All I need is to get the data in the speechmarks, whether both or just the one.

Cheers!

preg_match( '/"([^"]*)"/' , $string, $matches )  
# $matches is an array with the results
# ignore $matches[0]
# $matches[1] will contain the first string inside double-quotes
# $matches[2] will contain the second string inside double-quotes (if any)

If you are looking to replace text, following a certain regex would help:

OR, if you're not wanting to replace text, you can match it using:

Thanks for the help, I managed it in a slightly backwards way, using the basis of bowsersenior's answer and some simple counting!

    //Find amount of Speech marks
$stringCount = substr_count($newstring, '"'); 


if ($stringCount == 2){

    preg_match( '/".*?"/' , $newstring, $matches);

    foreach ($matches as $data) 
    {
    print_r($data);
    }


}else{

    //Get first speech marks

    preg_match( '/".*?"/' , $newstring, $matches);

    foreach ($matches as $data) 
    {
    print_r($data);
    }


    //Get second speech marks

     $endString =  substr($newstring,-4);

    echo $endString;


}
