CTYPE_LOWER(3)								 1							    CTYPE_LOWER(3)

ctype_lower - Check for lowercase character(s)

SYNOPSIS

       bool ctype_lower (string  $text)

DESCRIPTION

	Checks if all of the characters in the provided string, $text, are lowercase letters.

PARAMETERS

	      o $text
		- The tested string.

RETURN VALUES

	Returns TRUE if every character in $text is a lowercase letter in the current locale.

EXAMPLES

       Example #1

	      A ctype_lower(3) example (using the default locale)

	      <?php
	      $strings = array('aac123', 'qiutoas', 'QASsdks');
	      foreach ($strings as $testcase) {
		  if (ctype_lower($testcase)) {
		      echo "The string $testcase consists of all lowercase letters.
";
		  } else {
		      echo "The string $testcase does not consist of all lowercase letters.
";
		  }
	      }
	      ?>

	      The above example will output:

	      The string aac123 does not consist of all lowercase letters.
	      The string qiutoas consists of all lowercase letters.
	      The string QASsdks does not consist of all lowercase letters.

NOTES

       Note

	      ues have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string  contain-
	      ing the decimal digits of the integer.
