你好,我8天前刚开始学习PHP。我试图从SQL表中加载注释,并将它们按ID排序。要做到这一点,我想使用一个数组,并将注释id添加到索引中,这样它就会按顺序排列。
例:(这不是正确的代码)
while loop through SQL table{
array[3] = This is comment 3.
array[1] = This is comment 1.
array[0] = This is comment 0.
array[2] = This is comment 2.
}
正如您所看到的,它将注释按索引按正确顺序排列。我将如何在PHP中做到这一点?
以下是
最近,我试图使用PHP的array_udiff()函数来比较多维数组中的值和一个普通的旧字符串值。我试过这样的方法:
// E.g. $employees[0]["name"] = "Jeff";
// $currentEmployeeName = "Steve";
// This won't work because $a doesn't always correspond to $employees
array_udiff($employees, $currentEmployeeName, function($a,
我有一个数组,它包含一组数组元素,每个数组元素都包含两个元素。这是一个数组:
Array
(
Array(0.577677, '/art and entertainment/visual art and design/painting'),
Array(0.576528, '/technology and computing/internet technology/email'),
Array(0.197858, '/business and industrial/energy/oil/oil and gas prices'
我尝试使用下面的代码检查数组是否存在,问题是当getFieldOrder('image_gal')中没有图像时,它将返回此错误。
错误输出
Warning: array_reverse() [function.array-reverse]: The argument should be an array in /home/sritamac/public_html/wp-content/plugins/magic-fields/get-custom.php on line 306
Warning: sort() expects parameter 1 to be array,
如何在PHP中对对象进行排序?我尝试过shuffle(),但它需要一个数组:
Warning: shuffle() expects parameter 1 to be array,
object given in /var/www/index.php on line 366
Warning: Invalid argument supplied for foreach() in /var/www/index.php on line 334
这是我的代码:
public function updateStatusWithoutDB() {
$this->updateProfile
我在php手动站点上找到了一个数组排序函数,它可以做我想做的事情,但是它会生成警告,我一直在试图找出为什么和如何阻止它们。任何建议都会被采纳。
function fnArrayOrderby(){
//function to sort a database type array of rows by the values in one or more column
//source http://php.net/manual/en/function.array-multisort.php - user notes
//example of use -> $sorted = fnArray
