    Sure, here's an example of how you can use PHP's substr function to manipulate cryptocurrency data: $fullString = 'Bitcoin: $10,000'; $price = substr($fullString, strpos($fullString, '$') + 1); In this example, we have a cryptocurrency data string 'Bitcoin: $10,000'. We use the strpos function to find the position of the dollar sign ('$') in the string, and then use substr to extract the price portion of the string starting from the position of the dollar sign + 1. The resulting value of $price will be '10,000'. Hope this helps!

    Absolutely! You can use PHP's substr function to manipulate cryptocurrency data. Here's an example: $fullString = 'Ethereum: $500'; $name = substr($fullString, 0, strpos($fullString, ':')); In this example, we have a cryptocurrency data string 'Ethereum: $500'. We use the strpos function to find the position of the colon (':') in the string, and then use substr to extract the name portion of the string starting from position 0 and ending at the position of the colon. The resulting value of $name will be 'Ethereum'. I hope this explanation helps!

    Sure, you can use PHP's substr function to manipulate cryptocurrency data. Here's an example: $fullString = 'Litecoin: $150'; $currency = substr($fullString, 0, strpos($fullString, ':')); In this example, we have a cryptocurrency data string 'Litecoin: $150'. We use the strpos function to find the position of the colon (':') in the string, and then use substr to extract the currency portion of the string starting from position 0 and ending at the position of the colon. The resulting value of $currency will be 'Litecoin'. I hope this helps!
