Question

当我使用php打印字符串时，它会打印出像�C�a�r� �B�u�y�i�n�g�

这样的字符串

如何删除此�？

当我在html中使用这样的脚本工作正常

{category: "Auto", measure: 6600},

{category: "Best Car", measure: 22200},

{category: "Car Auction", measure: 5400},

{category: "Car Audio", measure: 60500},

{category: "Car Battery", measure: 6600},

但是当我尝试使用像这样的PHP打印时

<?php foreach($rows as $row){ ?>    
        {category: "<?php echo $row['ad_group']; ?>", measure: <?php echo $row['volume']; ?>},
    <?php } ?>

Answer 1

<强> FILTER_SANITIZE_STRING

<强> var_dump(filter_var($your_string_variable,FILTER_SANITIZE_STRING));

{category: "<?php echo 'Category'; var_dump(filter_var($row['ad_group'],FILTER_SANITIZE_STRING)); ?>", measure: <?php var_dump(filter_var($row['volume'],FILTER_SANITIZE_STRING)); ?>},

打印字符串时出错
