Split words and quoted strings

[mentalist]

Hi, this works with double quotes but fails on single quotes... I've been stuck on the wrong issue for a while so my heads boxed now lol

 

Any help much appreciated.

 

 

//$s='Test string [blog "xx yy" zz] one two three';
$s="Test string [blog 'xx yy' zz] one two three";

echo do_incode($s);

function do_incode($s){
    
    $a=array("blog");
    
    foreach($a as $e){
        
        $re="/\[".$e."(.+?)\]/";
        //$re='/\['.$e.'"(?:\\\\.|[^\\\\"])*"|\S+\]/';
        //$re='/\['.$e.' (`"([^"]*)"`)\]/';
        if(preg_match_all($re, $s, $matches, PREG_OFFSET_CAPTURE)){
            
            //$func=$this->api_register_get($e,'incode');
            $n=0;
            foreach($matches[0] as $ee){
                $va=str_getcsv(trim($matches[1][$n][0])," ");
                
                //$replace=$func($va);
                $replace=blog_incode($va);
                
                $re="/".preg_quote($ee[0])."/";
                $s=preg_replace($re,$replace,$s,1);        //    USE 1 TO LIMIT TO FIRST MATCH, FOR DUPLICATES...???
                
                $n++;
            }
        }
    }
    return $s;
}

function blog_incode($v){
    //$s="<b>*** INCODE [ :".$v[0].": ".(isset($v[1])?$v[1]:"")." ] WORKED ***</b>";
    $s="<b>*** INCODE [ :".$v[0].": ] WORKED ***</b>";
    return $s;
}

Could it have something to do with the fact that you're trying to use CSV parsing on data that is not CSV?

 

Should your regular expression be more specific, to match "blog" and "xx yy" and "zz" separately?

[mentalist]

In reality it can of arbitrary length and either quoted or not, or even nothing at all.
 
It does work as required when " are used, its just the ' case which doesn't......

Oops forgot that was the reason it was extracting the strings... no wonder the regex wasn't acting as expected

I'll be back ... thankyou

Burgers got in the way yum yum

 

 

function do_incode($s){
    
    $a=array("blog");
    
    foreach($a as $e){
        
        $re="/\[".$e."(.+?)\]/";
        if(preg_match_all($re, $s, $matches, PREG_OFFSET_CAPTURE | PREG_SPLIT_NO_EMPTY)){
           
            $n=0;
            foreach($matches[0] as $ee){
                //$va=str_getcsv(trim($matches[1][$n][0])," ");
                $re='/"(.*?)"|(=)|\'(.*?)\'| +/';
                $va=preg_split($re, trim($matches[0][$n][0],"[]"), -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
               
                $replace=blog_incode($va);
                
                $re="/".preg_quote($ee[0])."/";
                $s=preg_replace($re,$replace,$s,1);        //    USE 1 TO LIMIT TO FIRST MATCH, FOR DUPLICATES...???
                $n++;
            }
            
        }
    }
    return $s;
}

 

Good enough for now... Cheers for pointing out my daftness lol
