test.php为具体脚本

<?php

今天用wamp发现用了这么久的环境竟然php log日志默认没有打开。。。心塞~

赶紧脑补下

; Log errors to specified file. PHP’s default behavior is to leave this value
; empty.
; http://php.net/error-log
; Example:
;error_log = php_errors.log
; Log errors to syslog (Event Log on NT, not valid in Windows 95).
;error_log = syslog
;error_log = “d:/wamp/logs/php_error.log”

function strType($str){
$str =ord($str);
if($str>64&&$str<91){
//echo ‘大写字母’;
return 1;
}
if($str>96&&$str<123){
//echo ‘小写字母’;
return 2;
}
if(is_numeric($str)){
//echo ‘数字’;
return 3;
}
return 0;
}

其实就是通过ord来获取对应的ascii码值来区分大小写，详情查看http://www.asciitable.com/
