How to find and format all prices in a string with PHP

To find and format all prices in a string with PHP, you can use regular expressions to match patterns that look like prices and then format them using the number_format function.

Here is an example code snippet:

$string = "The price of the product is $9.99 and the shipping cost is $4.50.";

// Match all patterns that look like prices
preg_match_all('/\$\d+(\.\d{2})?/', $string, $matches);

// Loop through each match and format the price
foreach ($matches[0] as $match) {
    $price = (float) str_replace('$', '', $match);
    $formatted_price = number_format($price, 2);
    $string = str_replace($match, '$'.$formatted_price, $string);
}

echo $string;

To find and format all prices in a string with PHP, you can use regular expressions to match patterns that look like prices and then format them using the number_format function.

Here is an example code snippet:

$string = "The price of the product is $9.99 and the shipping cost is $4.50.";

// Match all patterns that look like prices
preg_match_all('/\$\d+(\.\d{2})?/', $string, $matches);

// Loop through each match and format the price
foreach ($matches[0] as $match) {
    $price = (float) str_replace('$', '', $match);
    $formatted_price = number_format($price, 2);
    $string = str_replace($match, '$'.$formatted_price, $string);
}

echo $string;

In this code, we use the preg_match_all function to find all patterns that look like prices in the $string variable. The regular expression /\$\d+(\.\d{2})?/ matches any string that starts with a dollar sign ($) followed by one or more digits (\d+) and optionally a decimal point followed by exactly two digits ((\.\d{2})?).

We then loop through each match and format the price using the number_format function. Finally, we use the str_replace function to replace the original price in the string with the formatted price.

This code will output: “The price of the product is $9.99 and the shipping cost is $4.50.”
