How to check existence of large number of remote images in php -


i displaying large number of remote images in php webpage , need check if image exists in-order-to handle no image condition. process takes heavy load check condition each remote file. please suggest views handle this.

thanks in advance.

i think there several solutions

  1. if display remote images (those images not located @ server) on webpage, can check if image exists javascript. mean create image , check if loaded. handle exception javascript.
  2. you can check image existence before displaying them users. example while adding them website. once, store results in database, , display images know exist.
  3. there php function curl_multi_exec. allows perform several http requests simultaneously.

you better copy images server. if do, sure images still exist , not modified.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
