php - PHP多维数组按条件搜索

问题描述

我正在开发一个金融网络应用程序我真的被这个问题所困扰。

如果条件为真，我需要使用条件搜索并返回数组..

我知道多维数组搜索，但对此我一无所知。例如 ：

if array[0][7] > array[0][8] && array[0][12] < array[0][15]

请建议我解决方案

  [0] => Array ( 
    [0] => 54452 
    [1] => 'KSB'
    [2] => 'INE999A01015'

解决方案

尝试以下代码并根据您的需要进行必要的更改

function search_sg_dma($array, $pre_close, $dma_value, $close_price){

...

    $result = array();
    for( $i = 0; $i < count( $array ); $i++ ) {
        if ( $array[$i][$pre_close] < $array[$i][$dma_value] && $array[$i][$close_price] > $array[$i][$dma_value] ) {
            $result[] = array[$i];
        }
    }
    return $result;
}
