我正在显示“儿子”这个词，然后是他们的名字，然后他们的数字和“女儿”这个词那么他们的名字就算了。我希望像这样显示儿子：a，b，c，d：4;
女儿：p，q，r，s：4;
$ all_categories是一个数组，其中我得到所有给定id的孩子，get_gender和get_cats是函数。

现在我显示 a，b，c，d，：4; 。我只想在数组的最后一个元素之后删除逗号我只想在儿子的数量大于2且女儿的数量相同的情况下才显示计数如果男孩数是1，那么“儿子：”一词;女儿也一样如果男孩数是2，那么“儿子：”a，b;女儿也一样如果男孩数大于2，那么“儿子：”a，b，c：3;女儿也一样我想显示与上面相同的结果我说。所以任何人都可以尝试这个???

要删除显示儿子和女儿的最后一个逗号，检查下一条记录是否存在然后附加逗号，否则转义逗号。

$all_categories=get_cats($cat);
$headingPrinted = false;
$childCount = 0;
for($i=0;$i<sizeof($all_categories);$i++)
{    

 $arr=get_gender($cat);

 if($arr[$i]=='0')

 {
    if (!$headingPrinted) {
     echo "&nbsp&nbsp"."Sons:";
      $headingPrinted = true;
    }  
 echo "&nbsp&nbsp".$all_categories[$i];


if(isset($all_categories[$i+1])){
      echo ",";

   }
 $childCount++;
 }



 } 
     if ($childCount >= 3) {
echo $childCount,  $childCount == 1 ;  
} 
else {
// you may want to do something if none found
}
$headingPrinted = false;
$childCount = 0;

for($i=0;$i<sizeof($all_categories);$i++)
{    

 $arr=get_gender($cat);



if($arr[$i]=='1'){
if (!$headingPrinted) {
     echo "&nbsp&nbsp"."Daughters:";
      $headingPrinted = true;
    }  
echo "&nbsp&nbsp".$all_categories[$i];
if(isset($all_categories[$i+1])){
  echo ",";



}
    $childCount++;
      }

  } 
 if ($childCount >= 3) {
 echo $childCount,  $childCount == 1 ;  
 } 
 else {
// you may want to do something if none found
 }

在codeigniter php中为每个数组元素显示不同的后缀
