how to replace special chars in php

Question

I have a code that i have to replace few special chars: code below:

#include <iostream>\012#include <stdio.h>\012#include <stdlib.h>\012#include <limits>\012#include <string.h>\012using namespace std;\012\012void inclean(){\012\011std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\\n');\012}\012\012void die(string e){\012\011//cout << e;\012\011exit(1);\012}\012\012typedef struct {\012\011bool zajente;\012\011int rozmiar;\012} pudelko;\012\012int main() {\012\011int i = 12;\012setvbuf(stdout, NULL, _IONBF, 0);\012\011setvbuf(stderr, NULL, _IONBF, 0);\012\011int a;\012\011int lamount=0;\012\011cin >> a;\012\011if(!(a>=1&&a<=1000000)){die("Liczba mo\277e wynosi\346 od 1 do 1000000(10^6)");}\012\011pudelko  *pudelka=new pudelko[a];\012\011memset (pudelka,0,a*sizeof(pudelko));\012\011string b;\012\011inclean();\012\011getline(cin,b);\012\011int bl=b.length();\012\011for(int i=0;i<=bl;i++){\012\011\011char c=b.c_str()[i];\012\011\011if (c>=48&&c<=57){\012\011\011\011pudelka[lamount].rozmiar*=10;\012\011\011\011pudelka[lamount].rozmiar+=(int)c-48;\012\011\011\011pudelka[lamount].zajente=false;\012\011\011} else {\012\011\011\011if(!(pudelka[lamount].rozmiar>=1&&pudelka[lamount].rozmiar<=1000000000)) die("Liczba mo\277e wynosi\346 od 1 do 1000000000(10^9)");\012\011\011\011lamount++;\012\011\011\011if(lamount>=a) break;\012\011\011}\012\011}\012\011int cpa=lamount;\012\011int e=0;\012\011while (true){\012\011\011for(int z=e;z<=cpa;z++)\012\011\011\011if(pudelka[z].rozmiar>pudelka[e].rozmiar&&!pudelka[z].zajente){\012\011\011\011\011pudelka[z].zajente=true;\012\011\011\011\011lamount--; break;\012\011\011\011}\012\011\011if(e>=cpa){ cout << "" << lamount+1; break; }\012\011\011e++;\012\011\011}\012\011exit(0);\012\011return(0);\012}\012

what i tried to remove \012 and \011 was

 $this->data['StoredFile']['data'] = str_replace("\012","\n",$this->data['StoredFile']['data']);
 $this->data['StoredFile']['data'] = str_replace("\011","\t",$this->data['StoredFile']['data']);

Also used

$this->data['StoredFile']['data'] = stripslashes($this->data['StoredFile']['data']);

wchich removed \0 and then by str_replace i removed 11 and 12... but i noticed that for e.x. int i = 12; was changed to int i = \n; what i dont wont to happen ;<

Answer 1

Use str_ireplace.

$output = str_ireplace (array('\012','\011'),array("\n","\t"), $string);

DEMO.

Answer 2

You can use the chr function to replace ascii characters with whatever char/string you need or want:

str_replace(array(chr(012), chr(011)), array("\n","\t"), $string);

AFAIK, that should do the trick, and should avoid your replacing anything by accident.
See the docs here.

That being said, there might be more ascii chars in your input string, so perhaps the iconv function is a better fit:

echo iconv('ASCII', 'UTF-8//IGNORE', $string);

The docs.
