php - substr function issue

When we use substr to display part of the string but if our string has anchor tag then displayed string content viewing smaller than others strings

e.g. 

$str1="is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It";

$str2="is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy <a href='http://www.google.com'>text</a> ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It";

$str1Count=strlen($str1); // 357

$str2Count=strlen($str2); // 393

if($str1Count > 300){
   echo substr($str1,0,300)."<br/><br/>";
}

/* 
output:

Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.

*/


if($str2Count > 300){
    echo substr($str2,0,300);
}

/*

This will do the trick but it will remove your hyperlink. do you want to keep hyperlink intact?

<?php

$str1Count=strlen(strip_tags($str1)); // 357

$str2Count=strlen(strip_tags($str2)); // 393

you may need to use strip_tags

echo substr(strip_tags($str2),0,300);

Note: Don't forget to use strip_tags when checking the length of the string also.

Use it

function limit_words($string, $word_limit){
    $words = explode(" ",$string);
    return implode(" ",array_splice($words,0,$word_limit));
}
