<?php
  $celsius = 25; // Change this value to the Celsius temperature you want to convert
  $fahrenheit = ($celsius * 9/5) + 32;
  echo $celsius."°C is equivalent to ".$fahrenheit."°F";
?>

In the above code, we first assign the Celsius temperature to the variable $celsius. We then apply the formula (C * 9/5) + 32 to convert Celsius to Fahrenheit and store the result in the variable $fahrenheit. Finally, we print the result using the echo statement.

You can replace the value 25 in the code with any other Celsius temperature you want to convert, and the code will calculate and display the equivalent Fahrenheit temperature.

<?php
  $fahrenheit = 72; // Change this value to the Fahrenheit temperature you want to convert
  $celsius = ($fahrenheit - 32) * (5/9);
  echo $fahrenheit."°F is equivalent to ".$celsius."°C";
?>

In the above code, we first assign the Fahrenheit temperature to the variable $fahrenheit. We then apply the formula (F - 32) * (5/9) to convert Fahrenheit to Celsius and store the result in the variable $celsius. Finally, we print the result using the echo statement.

You can replace the value 72 in the code with any other Fahrenheit temperature you want to convert, and the code will calculate and display the equivalent Celsius temperature.

There are many ways to catch catfish, but here are some general tips and techniques:

1. Choose the right location: Catfish can be found in lakes, rivers, and ponds, and they tend to congregate in areas with deep water, cover, and structure such as logs, rocks, or brush piles. Look for areas with slow-moving water and a muddy or sandy bottom.

2. Use the right gear: You will need a sturdy fishing rod and reel, heavy line (at least 15-pound test), a sinker, and a hook. A slip sinker rig is a popular choice for catfish, as it allows the bait to move more naturally in the water.

3. Use the right bait: Catfish are opportunistic feeders and will eat a variety of baits. Some popular choices include live or cut bait such as shad, bluegill, or worms, as well as stink baits, chicken liver, or hot dogs. It's a good idea to experiment with different baits to see what works best in your area.

4. Be patient: Catfish can be slow to bite, so it's important to be patient and wait for them to take the bait. You may need to wait several minutes or even hours before getting a bite.

5. Set the hook: When you feel a tug on the line, quickly reel in any slack and give the line a firm tug to set the hook. It's important to set the hook quickly and firmly to avoid the catfish spitting out the bait.

6. Handle with care: Catfish have sharp spines on their fins that can cause injury, so it's important to handle them carefully. Use gloves or a towel to hold the fish, and be sure to release it back into the water gently.

In terms of a good bait for catfish, as mentioned earlier, they will eat a variety of baits. Some popular choices include:

1. Live or cut bait: Shad, bluegill, sunfish, or minnows are all good choices.

2. Stink baits: These are commercially-made baits that have a strong odor to attract catfish.

3. Chicken liver or hot dogs: These are popular homemade baits that are cheap and effective.

Ultimately, the best bait for catfish will depend on your location and the specific conditions you're fishing in. It's a good idea to experiment with different baits to see what works best in your area.

While homemade remedies may not be as effective as commercial medications, here are a few home remedies that may help alleviate cold symptoms:

1. Honey and Lemon Tea: Mix honey and fresh lemon juice in a cup of hot water. Sip the tea slowly to soothe a sore throat and relieve congestion.

2. Saltwater Gargle: Mix a teaspoon of salt in a glass of warm water and gargle for a few seconds before spitting it out. This can help relieve sore throat and loosen mucus.

3. Chicken Soup: Chicken soup is a natural anti-inflammatory and can help relieve congestion and sore throat. It also helps keep you hydrated.

4. Ginger Tea: Boil fresh ginger slices in water for 10 minutes, then strain and add honey and lemon juice. Ginger has anti-inflammatory properties that can help alleviate cold symptoms.

5. Steam Inhalation: Boil water and pour it into a bowl, then lean over the bowl with a towel over your head to inhale the steam. This can help loosen mucus and relieve congestion.

It's important to note that if your cold symptoms persist or worsen, you should consult a healthcare professional.
