Checks if all of the characters in the provided string,
text, are alphabetic.
In the standard C
locale letters are just
[A-Za-z]
and ctype_alpha() is
equivalent to (ctype_upper($text) || ctype_lower($text))
if $text is just a single character, but other languages have letters that
are considered neither upper nor lower case.
Returns TRUE
if every character in text is
a letter from the current locale, FALSE
otherwise.
<?php
$strings = array('KjgWZC', 'arf12');
foreach ($strings as $testcase) {
if (ctype_alpha($testcase)) {
echo "The string $testcase consists of all letters.\n";
} else {
echo "The string $testcase does not consist of all letters.\n";
}
}
?>
The above example will output:
The string KjgWZC consists of all letters.
The string arf12 does not consist of all letters.
