使用php从内爆数据中删除第一个字符
问题描述：
I have the following code
<td class="t-value h6"><?php echo implode('<br> ', $datas);
this code dump result like this
a.first element<br>
B.seconds element<br>
c.third element <br>
d.etc
what I want is to hide the first and second character of each element I tried
<td class="t-value h6"><?php
$datas = implode('<br/>', $datas);
echo substr($datas, 2);
but that did work only for the first element and I want it to apply to all elements inside data
thanks verry mx
我有以下代码 p>
＆lt; td class = “t-value h6”＆gt;＆lt;？php echo implode（'＆lt; br＆gt;'，$ datas）;
code> pre>
此代码转储结果如下 p>
a.first element＆lt; br＆gt;
B.seconds element＆lt; br＆gt;
c.third element＆lt; br＆gt;
d.etc
code> pre>
我想要的是隐藏我尝试的每个元素的第一个和第二个字符 p>
＆lt; td class =“t-value h6“＆gt;＆lt;？php
$ datas = implode（'＆lt; br /＆gt;'，$ datas）;
echo substr（$ datas，2）;
code> pre>
但这只适用于第一个元素，我希望它适用于数据中的所有元素 p>
谢谢你们 mx p>

You can use regex to do this work in preg_replace() function
$newDates = preg_replace("/^\w\./m", "", $dates)
Check result in demo

Work with each array element separately and then do implode.
$data2 = array();
foreach($datas as $d){
$data2[] = substr($d, 2);
}
$data2 = implode('<br/>', $data2);

It is probably easier to use preg_replace for this, depending on your willingnes to use regexp.
For example this would solve the issue as long as you do not have the same pattern somewhere else.
$output = preg_replace("/\w\./", "", $datas);
