删除字符串中的第一个html标记

Question

i have this text

<?php
   $example1 = '<b class="counter">1</b> This is a computer';
   $example2 = '<b class="counter">5</b> i have a laptop';
   $example3 = '<b class="counter">1</b> i need a smartphone';
   $example4 = 'i need a car'; // does not have <b> tag
?>

i'm looking for a php function to remove a part of the string, starting from <b> to </b>, so the results should be like :

$example1_result = 'This is a computer';
$example2_result = 'i have a laptop';
$example3_result = 'i need a smartphone';
$example4_result = 'i need a car';

Answer 1

Make sure to escape from your "counter" otherwise it will not work, but the others have already answered your question with a better version using regular expressions.

<?php
$example1 = "<b class=\"counter\">1</b> This is a computer";
$example2 = "<b class=\"counter\">5</b> i have a laptop";
$example3 = "<b class=\"counter\">1</b> i need a smartphone";

echo strip_tags($example1); //Outputs: 1 This is a computer

$example1 = trim(substr(strstr($example1, '</b>'), strlen('</b>')));
echo $example1; //Outputs: This is a computer
