Version 1

The function checks if the folder exists, if the file exists and if the phrase contains the needed format indexes.

PHP Code:

stock bool TranslationExists(char[] phrase, char[] file)
{
    char cfgFile[PLATFORM_MAX_PATH];
    char dirName[PLATFORM_MAX_PATH];
    
    BuildPath(Path_SM, dirName, PLATFORM_MAX_PATH, "translations");
    BuildPath(Path_SM, cfgFile, PLATFORM_MAX_PATH, "translations/%s.txt", file);
    
    if (!DirExists(dirName) || !FileExists(cfgFile))
    {
        return false;
    }
    
    Handle kv = CreateKeyValues("Phrases");
    FileToKeyValues(kv, cfgFile);
    
    if (KvJumpToKey(kv, phrase))
    {
        char bufferformat[255];
        KvGetString(kv, "#format", bufferformat, sizeof(bufferformat), "");
        
        bool contains[16];
        bool passed = false;
        if (!StrEqual(bufferformat, ""))
        {
            for (int i = 1; i < sizeof(contains); i++)
            {
                char buffer[4];
                Format(buffer, sizeof(buffer), "{%d:", i);
                if (StrContains(bufferformat, buffer) != -1)
                {
                    passed = true;
                    contains[i] = true;
                }
                else
                {
                    contains[i] = false;
                }
            }
        }
        
        char bufferphrase[255];
        KvGetString(kv, langname, bufferphrase, sizeof(bufferphrase), "");
        
        if (StrEqual(bufferphrase, ""))
        {
            return false;
        }
        
        if (passed)
        {
            for (int i = 1; i < sizeof(contains); i++)
            {
                if (contains[i])
                {
                    char buffer[4];
                    Format(buffer, sizeof(buffer), "{%d}", i);
                    if (StrContains(bufferphrase, buffer) == -1)
                    {
                        return false;
                    }
                }
            }
        }
    }
    else
    {
        return false;
    }
    CloseHandle(kv);
    
    return true;
} 


Call it like this:

PHP Code:

if (TranslationExists("Changing map", "common.phrases"))
{
    PrintToChat(client, "%t", "Changing map", map)
}
else
{
    PrintToChat(client, "Changing map to %s...", map)
} 


Version 2

The function checks if the folder exists, if the file exists and if the phrase contains the needed format indexes.
It's coded using SMC Parser, which will prevent any bugs related with multi-line comments in the file.

PHP Code:

The code will cache the valid translations in an array. Then it will simply check if that translation is available in the array in the client language, server language or English.
