HomeBackend DevelopmentPHP Tutorial利用PHP内建函数和htaccess修改php.ini参数

前几天写一个程序的时候,有一个脚本的执行时间比较长,100s+,但是php.ini默认的脚本超时时间是30s,所以自然而然的中断了,加上set_limit_time(0),发现函数被禁用了,汗。

到论坛问客服,客服说因为是共享服务器,为了避免某一个虚拟机内的脚本有死循环,使CPU飙升,就关闭了这个函数,听到这个结果,我异常蛋疼。

在蛋疼了一天以后,有个会员给提供了一个方法,利用htacces修改脚本超时时间等php.ini参数。试了一下,嘿,还真可以,又忽然想到了ini_set()这个函数,试了一下,依然可以,哇嘎嘎,我可以邪恶了~

实例:

# 先以htaccess为例
# 示例:
# php_value 参数名 参数值
# 实例:
php_value max_execution_time 600
# 这样,脚本超时时间就改为了600(十分钟)了

这是.htaccess的写法,不过貌似这样写之后,rewrite都失效了?反正我同目录下的dz伪静态没用,一直404,汗,方便没好货啊,不过如果禁用了ini_get和ini_set,这个方法还是可取的。

下面看php的:

<?php echo "修改前:".ini_get("max_execution_time");
if(ini_set("max_execution_time",600))
echo "修改ing...";
else
exit("ini_set()函数被禁用");
sleep(3);
echo "修改后:".ini_get("max_execution_time");
?>


刚才忘了,最后加一句:htaccess那个只能用于 PHP_INI_ALL 或 PHP_INI_PERDIR 类型的指令,其它的不行。

php怎么把负数转为正整数php怎么把负数转为正整数Apr 19, 2022 pm 08:59 PM

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

php怎么判断有没有小数点php怎么判断有没有小数点Apr 20, 2022 pm 08:12 PM

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
