Thread: ReplaceChars Function

/*
* Replaces characters in a string
* Usage: strreplace(string, 'Input Text', 'Replacing Text');
*/

This function is quite handy for me, and I've been using it for a while.

Code :

stock replacechars(string[], match, replace)
{
  for(new i=0; string[i]; i++)
  {
    if(string[i] == match)
    {
      string[i] = replace;
    }
  }
}

Enjoy.

Code :

public ReplaceCharacter(string[], match, replace)
{
	new iWrite = strlen( string ), count;
	do
	{
	  if( string[count] == match )
      string[count] = replace;
	}
	while( iWrite < count++ );
}

Your code doesn't do what you said, it'll just replace the character in the instant I.

If you had a roleplay name and you'd want to remove the underscore off the name like: Jack_London, this would be the appropriate thing to use (or things).

These can be used as well:

Code :

#if !defined isnull
	#define isnull(%1) (((%1[0]) == '\0') || (((%1[0]) == '\1') && ((%1[1]) == '\0')))
#endif
 
/**
 * Replace a substring in a string
 * @param	string		The source string
 * @param	find		The substring to be replaced
 * @param	replace		The substring to replace with
 * @param	ignorecase	If the search is case insensitive
 * @param	count		The number of substrings to be replaced

 */
stock strreplace(string[], const find[], const replace[], bool:ignorecase=false, count=cellmax, maxlength=sizeof(string))
{
	if(isnull(find) || isnull(string)) return 0;
	new matches;
	for(new idx, flen = strlen(find), rlen = strlen(replace), pos = strfind(string, find, ignorecase); pos != -1 && idx < maxlength && matches < count; pos = strfind(string, find, ignorecase, idx)) {
		strdel(string, pos, pos + flen);
		if(rlen) strins(string, replace, pos, maxlength);	// Crashy
		idx = pos + rlen;
		matches++;
	}
	return matches;
}
