php - substr function issue

Question

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:
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 el
*/


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

/*

*/

but as per my need it has to display till "into el"

please help me thanks in advance.

seriously, these were the shortest string examples you could come up with? :/ how about truncating to 20 characters? — Karoly Horvath

have you tried echo htmlspecialchars(substr($str2,0,300)); (asuming you are displaying the result in a browser)? — bansi

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.

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

Use it

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