Yii2：如何在foreach循环中使用rtrim？

Question

I'm getting images from database which holds path of the images each path is separated by ';' i need to ignore the last ';' because when it is displaying the images from db its getting last ';' and showing broken thumbnail in view

<?php
foreach (explode(';', $row['images']) rtrim($row['images'],';') as $key_img => $value_img)
{
echo Html::img(Yii::getAlias('@web').'/'.$value_img,[
' height'=> 500,
'width'=> 500,
]);
}
?> 

Answer 1

If you want explode the result of rtrim you shold do this way

foreach (explode(';',  rtrim($row['images'],';')) as $key_img => $value_img)

or you could need a substr

yourString =  substr($row['images'],strlen($row['images'])- 1);
