I have a error:

L 08/02/2014 - 13:13:02: replace() buffer not big enough (64>=63)
L 08/02/2014 - 13:13:02: [AMXX] Run time error 10: native error (native "replace")

code looks like this

PHP Code:

new nazwa_gracza[33][128];
public client_putinserver(id) {    
    if(is_user_hltv(id) || is_user_bot(id)) return;

    return 0;
}

} 


line 236:

PHP Code:

line 125 (in the client_infochanged):

PHP Code:

SQL_PrepareString(nazwa_gracza[id], name); 


what causes this error?

[GordonFreeman (RU)]

Try use this stock:

stock replace_all2(string[], len, const what[], const with[])
{
	new pos = 0;
	
	if ((pos = contain(string, what)) == -1)
	{
		return 0;
	}
	
	new total = 0;
	new with_len = strlen(with);
	new diff = strlen(what) - with_len;
	new total_len = strlen(string);
	new temp_pos = 0;
	
	while (total_len + with_len < len && replace(string[pos], len - pos, what, with) != 0)
	{
		total++;

		/* jump to position after replacement */
		pos += with_len;
		
		/* update cached length of string */
		total_len -= diff;
		
		/* will the next call be operating on the last character? */
		if (pos >= total_len)
		{
			break;
		}
		
		/* find the next position from our offset */
		temp_pos = contain(string[pos], what);
		
		/* if it's invalid, we're done */
		if (temp_pos == -1)
		{
			break;
		}
		
		/* otherwise, reposition and update counters */
		pos += temp_pos;
	}
	
	return total;
}

The error is caused by replacing eg. 2 characters with 4 characters, as you have done and the string array cannot fit it in.

[OnePL]

how to fix it?
some characters need to change with more characters eg \\ -> \\\\ to save data to sql was correct

Make the buffer bigger
