在foreach中的多维数组 [英] Multidimensional array in foreach

问题描述

我只想在 myformdata [languages1] [] 的内容不为空（包括零）的情况下执行foreach

我已经试过了：

$ $ $ $ $ $ $ $ $ $ $ ）{

和

if（！empty（$ form ['languages1'] []））{
foreach（$ form ['languages1'] as $ val）{
// do stuff
}

我不在下面的代码中，当 myformdata [languages1] [] 的输入是 0


foreach


  foreach（$ form ['languages1'] as $ val）{
 // do stuff 
} 
  

谢谢解决方案

foreach（$ form [ '语言1']为$ val）
{
//如果该值为空，则跳到下一个
if（empty（$ val））
continue;

i want to do the foreach only if the content of myformdata[languages1][] is not empty (include zero)

I already try:

  foreach((!empty($form['languages1']) as $val){

and

if (!empty($form['languages1'][])) {
foreach($form['languages1'] as $val){
//do stuff
}

i don't have any success. At the moment with the code below the loop is made when the input of myformdata[languages1][] is 0

foreach

foreach($form['languages1'] as $val){
//do stuff
}

thanks

解决方案

foreach ( $form['languages1'] as $val )
{
  // If the value is empty, skip to the next.
  if ( empty($val) )
    continue;
}
