Question

我需要在字符串的开头删除所有出现的“0”：

00000012322   //  i would like to get 12322
0011330322    //  i would like to get 11330322

我怎么能用PHP做到这一点？

Answer 1

使用PHP的ltrim()功能：

  <div class="form-group">
  <div class="row">
    <div class="col-3">
     <label for="exampleFormControlInput1">Bobs</label>
    </div>
    <div class="col-6">
    <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
    </div>
    <div class="col-3">
    I need text here
    </div>
  </div>
</div></div>

您可以通过强制PHP将其更改为数字

来轻松破解它

$var = "00000012322";
echo $var+0;
//or
echo floatval($var);

我想注意，这会导致您的变量类型改变，这可能不是您想要的！正如其他人指出的那样，ltrim()可以做到这一点。您也可以使用strval()转换回字符串，但这肯定比ltrim更昂贵......所有都取决于用法。
