ctype_punct — 检测可打印的字符是不是不包含空白、数字和字母
示例 #1 ctype_punct() 示例
<?php
$strings = array('ABasdk!@!$#', '!@ # $', '*&$()');
foreach ($strings as $testcase) {
if (ctype_punct($testcase)) {
echo "The string $testcase consists of all punctuation.\n";
} else {
echo "The string $testcase does not consist of all punctuation.\n";
}
}
?>
以上示例会输出:
The string ABasdk!@!$# does not consist of all punctuation. The string !@ # $ does not consist of all punctuation. The string *&$() consists of all punctuation.
