How can a specific character be removed once from a string in PHP?

To remove a specific character once from a string in PHP, you can use the `str_replace` function with a limit parameter set to 1. This will replace the first occurrence of the specified character with an empty string. 

$string = "Hello World!";
$charToRemove = "o";
$newString = substr_replace($string, "", strpos($string, $charToRemove), 1);

echo $newString; // Output: Hell World!
