I wrote most of this working and beginner PHP script and I'd appreciate it if you would possibly review it and help me to replace slugCompany method (which only iterates ~8000 times) in the UpdateStocks class with a faster or simpler method.



Method:



/**

* 

* @return a string of company name without common words to be embedded in the URL

*/

public static function slugCompany($c){

    $c=strtolower($c);

    $c=preg_replace('/[^da-zs]/i', '', $c);

    $words=self::COMPANY_STOPWORDS;

    $c=preg_replace('/b('.$words.')b/i', '', $c);

    $c=preg_replace('/(s+)/i', '-', trim($c));

    return $c; 

}


Constant:



const COMPANY_STOPWORDS = '11000th|american|and|a|beneficial|bond|b|class|common|company|corporation|corp|commodity|cumulative|co|c|daily|dep|depositary|depository|debentures|diversified|due|d|each|etf|equal|equity|exchange|e|financial|fund|fixedtofloating|fixed|floating|f|group|g|healthcare|holdings|holding|h|inc|incorporated|interests|interest|in|index|income|i|junior|j|k|liability|limited|lp|llc|ltd|long|l|markets|maturity|municipal|muni|monthly|m|noncumulative|notes|no|n|of|one|or|o|portfolio|pay|partnership|partner|par|perpetual|per|perp|pfd|preference|preferred|p|q|redeemable|repstg|representing|represents|rate|r|sa|smallcap|series|shs|shares|share|short|stock|subordinated|ser|senior|s|the|three|term|to|traded|trust|two|t|ultrashort|ultra|u|value|v|warrant|weight|w|x|y|z';


Call:



$cn=strtolower(UpdateStocks::slugCompany($s["quote"]["companyName"])); // slug company

    You wrote most of it, i.e. this is not your code? You also state: "desired output", does it not produce the desired output?

I wrote most of this working and beginner PHP script and I'd appreciate it if you would possibly review it and help me to replace slugCompany method (which only iterates ~8000 times) in the UpdateStocks class with a faster or simpler method.



Method:



/**

* 

* @return a string of company name without common words to be embedded in the URL

*/

public static function slugCompany($c){

    $c=strtolower($c);

    $c=preg_replace('/[^da-zs]/i', '', $c);

    $words=self::COMPANY_STOPWORDS;

    $c=preg_replace('/b('.$words.')b/i', '', $c);

    $c=preg_replace('/(s+)/i', '-', trim($c));

    return $c; 

}


Constant:



const COMPANY_STOPWORDS = '11000th|american|and|a|beneficial|bond|b|class|common|company|corporation|corp|commodity|cumulative|co|c|daily|dep|depositary|depository|debentures|diversified|due|d|each|etf|equal|equity|exchange|e|financial|fund|fixedtofloating|fixed|floating|f|group|g|healthcare|holdings|holding|h|inc|incorporated|interests|interest|in|index|income|i|junior|j|k|liability|limited|lp|llc|ltd|long|l|markets|maturity|municipal|muni|monthly|m|noncumulative|notes|no|n|of|one|or|o|portfolio|pay|partnership|partner|par|perpetual|per|perp|pfd|preference|preferred|p|q|redeemable|repstg|representing|represents|rate|r|sa|smallcap|series|shs|shares|share|short|stock|subordinated|ser|senior|s|the|three|term|to|traded|trust|two|t|ultrashort|ultra|u|value|v|warrant|weight|w|x|y|z';


Call:



$cn=strtolower(UpdateStocks::slugCompany($s["quote"]["companyName"])); // slug company

I wrote most of this working and beginner PHP script and I'd appreciate it if you would possibly review it and help me to replace slugCompany method (which only iterates ~8000 times) in the UpdateStocks class with a faster or simpler method.



Method:



/**

* 

* @return a string of company name without common words to be embedded in the URL

*/

public static function slugCompany($c){

    $c=strtolower($c);

    $c=preg_replace('/[^da-zs]/i', '', $c);

    $words=self::COMPANY_STOPWORDS;

    $c=preg_replace('/b('.$words.')b/i', '', $c);

    $c=preg_replace('/(s+)/i', '-', trim($c));

    return $c; 

}


Constant:



const COMPANY_STOPWORDS = '11000th|american|and|a|beneficial|bond|b|class|common|company|corporation|corp|commodity|cumulative|co|c|daily|dep|depositary|depository|debentures|diversified|due|d|each|etf|equal|equity|exchange|e|financial|fund|fixedtofloating|fixed|floating|f|group|g|healthcare|holdings|holding|h|inc|incorporated|interests|interest|in|index|income|i|junior|j|k|liability|limited|lp|llc|ltd|long|l|markets|maturity|municipal|muni|monthly|m|noncumulative|notes|no|n|of|one|or|o|portfolio|pay|partnership|partner|par|perpetual|per|perp|pfd|preference|preferred|p|q|redeemable|repstg|representing|represents|rate|r|sa|smallcap|series|shs|shares|share|short|stock|subordinated|ser|senior|s|the|three|term|to|traded|trust|two|t|ultrashort|ultra|u|value|v|warrant|weight|w|x|y|z';


Call:



$cn=strtolower(UpdateStocks::slugCompany($s["quote"]["companyName"])); // slug company

I would clean it up a bit:



public static function slugCompany($company){

    $replace = [

        '/[^da-zs]/i'                        => '', //remove punctuation I guess

        '/b('.self::COMPANY_STOPWORDS.')b/i' => '', //remove these companies

         '/^s+|s+$/'                         => '', //trim

         '/s+/'                               => '-' //replace space with -

    ];



    return preg_replace(array_keys($replace), $replace, strtolower($company));

}


I cleaned up all these local variables, got rid of a few repetitive calls. The array_keys and array structure are mainly for readability reasons and ease of use. For example now you can easly add replacements if you need to because they use a common array for the replacements.



Sandbox



Its more of a readability fix as it's hard to know all the input you may have so I have to trust that you covered all the edge cases.



Your code



Hope it helps.

    Sure all I did is re-arange some stuff. I usually write my own code 3 or 4 times before I am happy with it. Once to get it working, once to make it readable and once to improve the performance. Don't be afraid to say this is too much I need to simplify it. Its a process like writing an English paper.

Sure all I did is re-arange some stuff. I usually write my own code 3 or 4 times before I am happy with it. Once to get it working, once to make it readable and once to improve the performance. Don't be afraid to say this is too much I need to simplify it. Its a process like writing an English paper.
