Python က 1 second နဲ့ 3 MB ရှိတဲ့ file ကိုပြီးတယ်။ PHP ကတော့ 29 seconds လောက်ကြာတယ်။ python က ၁၅ လိုင်း။ php က ၂၃ လိုင်း။ အချိန်တွက်တာ မပါရင်တော့ လိုင်း ၁၉ ပေါ့။ ဒီထက်တိုအောင် ထပ်ရေးမယ်ဆိုရင်တော့ ၁၇ လိုင်းလောက်နဲ့ ပြီးတယ်။ ရှင်းအောင် ရေးထားလို့ပါ။ PHP နဲ့ ၁၅ လိုင်းလောက်နဲ့ရအောင် ရေးလို့ရတယ်။ ဒါပေမယ့် ဖတ်ရတာ ရှုပ်သွားမှာဆိုးလို့။
:-) Cool!
Here what your PHP code will work…
1.) Read line by line and store as String
2.) Split String into array
That’s un-necessary. You can done it in one step. And why don’t you use file_get_contents() and file_put_contentes()..?
OK, try again with this…
$d = file_get_contents($argv[1]);
$fh = fopen($myFile, ‘r’);
while($line = fgets($fh)) {
$k = split(” “,$line);
if(strripos($d, $k[1])) $d = str_replace($k[1], $k[0], $d);
}
fclose($fh);
file_put_contents(“convert_”.$argv[1], $d);
I think,
>> $d = str_replace($k[1], $k[0], $d)
should be
>>$d .= str_replace($k[1], $k[0], $d);
Cheers
its get faster? just curious :D
I interest in this issue. Please let me know if you got new bench-mark…
Thanks…
Oop! new code is slower than old. It take 35 seconds. file_get_contents() and file_put_contents is not faster than fopen() ,fread(), fwrite(). Old code take just 31 seconds. :D Python is very faster than PHP. But New code is very short and clear system.
Thank you Ko Ei Maung

It should be. At lease it should faster 2x. Tweaked two loops to one loop.

Well, I’m not sure. It should faster. Technically, file_get_contents() will instantly load file content onto Memory. It should more faster. No more un-necessary Object creation. There might be another bottleneck in you code…
If you show me your detail code, I can fix it for you. I’m pretty sure there was not that much performance gap between PHP and Python…
Thanks…
