How to convert the first letter of a string to uppercase in PHP

Topic: PHP / MySQL« Prev|Next »

Answer: Use the PHP ucfirst() function

You can use the PHP ucfirst() function to change the first character of a string to uppercase (i.e. capital). Alternatively, you can use the strtolower() function in combination with the ucfirst() function, if you want to make only first letter of the string to uppercase and rest of the string to lowercase.

  • <?php
  • $str1 = 'the color of the sky is blue.';
  • echo ucfirst($str1);
  • echo "<br>";
  • $str2 = 'the Color of the Sky is Blue.';
  • echo ucfirst(strtolower($str2));
  • ?>
