php - is it possible to shrink preg_replace and str_replace -

-

Is it possible to make it more smooth with the lower line of code because I have to repeat it for every new box Enter 

  $ fil_namn = str_replace ("5FSE_", "", $ fil_url); $ Fil_namn = str_replace (".pdf", "", $ fil_namn); $ Fil_namn = str_replace (".docx", "", $ fil_namn); $ Fil_namn = str_replace (".doc", "", $ fil_namn); $ Fil_namn = preg_replace ("[_]", ".", $ Fil_namn); $ Fil_namn = preg_replace ('/ ^ [0-9] + \. +', '', $ Fil_namn); $ Fil_namn = preg_replace ("[AAA]", "one", $ fil_namn); $ Fil_namn = preg_replace ("[AEA]", "A", $ fil_namn); $ Fil_namn = preg_replace ("[oo]", "o", $ fil_namn); $ Fil_namn = preg_replace ("[AAA]", "A", $ fil_namn); $ Fil_namn = preg_replace ("[AEA]", "A", $ fil_namn); $ Fil_namn = preg_replace ("[oOo]", "o", $ fil_namn); $ Fil_namn = str_replace (".", "", $ Fil_namn);

You can use it: 

  Str_replace (array ('5FSE_', '.pdf', '.docx', '.doc'), '', $ fill_namn);    
  str_replace  allows for an array. 
 
 You can also: 
 
  $ string = "Hello"; Arrow ("A", "L", "E", "X"), $ string (ARE ("H", "E", "L", "O"), array  
 
 This will print  Aeeex . 
 
 Another method  string ()  function: 
 
  $ string = "[AAA] [OOO]"; $ Find = array ("[AAA]", "[AAA]", "[AAA]", "[AAA] [AAA] [OAO] [AO]] [AAA] $ [Array] "," [AO] "," [AAA] "," [AAA] "," [oo] "); = $ = array (" one "," one "," ö "," Å "," Ä "," ö "); echo string ($ string, array_combin ($ find, replace $));  
 
 It does the following:
