如何屏蔽掉phpinfo()函数
Submitted by on 2005, May 11, 10:10 AM

在 php.ini 配置文件里面有这个选项

disable_functions = ; This directive allows you to disable certain
; functions for security reasons. It receives
; a comma separated list of function names.
; This directive is *NOT* affected by whether
; Safe Mode is turned on or off.

写成
disble_function = phpinfo

几点提高php序运行效率的方法
Submitted by on 2005, May 11, 10:07 AM
1、用i+=1代替i=i+1。符合c/c++的习惯,效率还高。
2、尽可能的使用PHP内部函数。自己编写函数之前要详细查阅手册,看有没有相关的函数,否则费力不讨好。
3、能使用单引号字符串尽量使用单引号字符串。单引号字符串的效率要高于双引号字符串。
4、用foreach代替while遍历数组。遍历数组时foreach的效率明显高于while循环,而且不需要调用reset函数。两种遍历方法如下:
reset ($arr);
while (list($key, $value) = each ($arr)) {
echo "Key: $key; Value: $value
n";
}
foreach ($arr as $key => $value) {
echo "Key: $key; Value: $value
n";
}

Including using logical AND (&&) to judge multiple conditions, using logical OR (||) to judge at least one condition, using logical NOT (!) to judge the negation of a single condition, as well as nesting if statements and using parentheses to clarify priority.
