While experimenting with regex I've noticed that the function MatchRegex doesn't work as expected. And what I mean by this is that it only returns the first match.

Is there a way to enable global matching (modifier "/g") so that it returns all occurences within the string, instead of only the first one?

Code used:

PHP Code:

#include <sourcemod>
#include <sdktools>
#include <regex>

#pragma semicolon 1
#pragma newdecls required

Regex regex;

public void OnPluginStart()
{
    regex = CompileRegex("[^a-z 1-9#\\.]+", PCRE_CASELESS|PCRE_UTF8);
    
    if (!regex)
    {
        SetFailState("Invalid regex pattern");
    }
    RegConsoleCmd("sm_test", Command_Test);
}

public Action Command_Test(int client, int args)
{
    char test[100] = "« • # . 123 Test";
    char substr[100];
    
    int captures = MatchRegex(regex, test);
    if (captures > 0)
    {
        for (int i = 0; i < captures; i++)
        {
            bool match = GetRegexSubString(regex, 0, substr, sizeof(substr));
            
            if (!match)
            {
                break;
            }
            else ReplaceString(test, sizeof(test), substr, "", false);
        }
    }
    
    PrintToChat(client, "Captures: %d", captures);
    PrintToChat(client, "String: %s", test);
    return Plugin_Handled;
} 


In-game debugging:

Captures: 1 String: • # . 123 Test
