这样的数组怎么用循环取到里面的值比如取里面的 post_title

这样的数组怎么用循环取到里面的值比如取里面的 post_title

这是一个含有三个WP_Post Object对象元素的数组，获取元素对象后，再获取其属性即可，代码如下：

foreach($array as $key => $value){
    if($value->post_title)
        echo $value->post_title;
}

递归循环读取

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”。

php怎么实现几秒后执行一个函数Apr 24, 2022 pm 01:12 PM

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怎么除以100保留两位小数Apr 22, 2022 pm 06:23 PM

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怎么根据年月日判断是一年的第几天Apr 22, 2022 pm 05:02 PM

判断方法：1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式；2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的，因此真实天数需要在此基础上加1。

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。

php字符串有没有下标Apr 24, 2022 am 11:49 AM

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。

php怎么替换nbsp空格符Apr 24, 2022 pm 02:55 PM

方法：1、用“str_replace(" ","其他字符",$str)”语句，可将nbsp符替换为其他字符；2、用“preg_replace("/(\s|\&nbsp\;||\xc2\xa0)/","其他字符",$str)”语句。

php怎么读取字符串后几个字符Apr 22, 2022 pm 08:31 PM

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。
