Madami mga advisor diyan na nagsasabi na wag gawin emergency fund ang credit card, but I don't agree. Well, my credit card is not my first line of defense -- it's actually a bit down the line -- but in dire and urgent situations, it can really help.
This post by sentry on PEX explains it the best (this is also how I categorize emergencies and funds that may be required):

at least 3 months worth of our expenses are in savings banks
2. SEMI-URGENT (within the week/month) and/or BIG CASH NEEDED (i.e. job loss)
the other 3 months in managed funds - you may gain, or lose though but risk is medium
3A. WORST CASE SCENARIO - SEMI-URGENT (within the week/month), VERY BIG CASH NEEDED:
i may consider cashing in some investments like stocks (you may incur significant loss but emergency is emergency and this is worst case scenario already)
note: this is why in investments, i also take note of the liquidity, and try to balance so i wont end up with near-100% illiquid investments (i.e. 100% in real-estate)
3B. WORST CASE SCENARIO - URGENT (within the day/week/month), VERY BIG CASH NEEDED:
the alternative is to use credit cards or credit lines. this is if cashing investments will incur huge loss (i.e. during economic downturn). expect to incur significant loss due to credit interest, but at least it will buy you time, as against cashing in investments and incurring loss immediately.
the risk here is falling into debt trap.
4. WORST CASE SCENARIO - NON-URGENT (within 6 month), VERY BIG CASH NEEDED:
consider to cash in real estate properties.
note that the worst case scenarios (3-4) are sometimes not considered financial decisions anymore, but personal ones, and you may be willing to accept financial drawbacks over personal loss (i.e. the life of your child is at stake)"
