将多维数组中的数字字符串转换为int [英] Convert numeric strings in multi-dimensional array to int

问题描述

我有一个多维数组:

array(3) {
    [0]=> array(2) {
        [0]=> string(3) "ABC"
        [1]=> string(3) "744"
    }
    [1]=> array(2) {
        [0]=> string(3) "DEF" 
        [1]=> string(2) "86"
    }
    [2]=> array(2) {
        [0]=> string(3) "GHI" 
        [1]=> string(1) "2"
    }
} 

现在，我要将数字的字符串类型值转换为整数类型.

Now I want to convert the string-type values which are numbers to integer type.

Ex 744 是字符串，但应为整数.

Ex 744 is string but it should be integer.

在搜索论坛后，我尝试了一些功能，但没有成功.稍后，我必须在 json_encode()函数中使用此数组，并且在我的javascript处理中，数字值必须为整数类型.

I have tried a few functions after searching forums but with no success. Later I have to use this array in json_encode() function and in my javascript process numeric values must be integer-type.

推荐答案

$variable = array(3) { 
        [0]=> array(2) { 
                        [0]=> string(3) "ABC" 
                        [1]=> string(3) "744" } 
        [1]=> array(2) { 
                         [0]=> string(3) "DEF" 
                         [1]=> string(2) "86" } 
        [2]=> array(2) { 
                         [0]=> string(3) "GHI" 
                         [1]=> string(1) "2"  }
    } 

foreach($variable as $key=>$arrayStrings)
    foreach($arrayStrings as $innerKey=>$string)
           if(is_numeric($string))
              $variable[$key][$innerKey] = intval($string);
