I am currently working on a php project where I need to display a string up to a maximum of 100 characters but without splitting the word.
For example if I have the string
The quick brown fox jumped over the lazy dogs back
Say the 100th character is in the middle of 'jumped'. At the moment I am using substr($mystring, 0, 100)
This will then print
The quick brown fox jum
Instead in this case I would want to print
The quick brown fox
Is this possible to fix
$string = 'The quick brown fox jumped over the lazy dogs back';
$maxLength = 20;
if (strlen($string) > $maxLength) {
$stringCut = substr($string, 0, $maxLength);
$string = substr($stringCut, 0, strrpos($stringCut, ' '));
}
echo $string;
// output: The quick brown fox
The key is using strrpos to cut off at a space rather than the middle of a word.
Note: If the source for these strings uses a multibyte charset, eg, UTF-8, you will want to use the multibyte equivalent functions.
PHP's wordwrap() function can help. http://php.net/manual/en/function.wordwrap.php
It's kinda hacky due to the separator string, but is concise:
$str2 = wordwrap($str,20,'@@@@@');
$str_final = substr($str2,0,strpos($str2,'@@@@@'));
Note that this will break if your original string contains '@@@@@', I'm using it as a unique separator that I figure will not be present in most english strings. Feel free to change '@@@@@' to something more wonky/unique.
//Set up - we need 100 characters
$s="The quick brown fox jumped over the lazy dogs back";
$s="$s. $s. s.";
//Cut
$t=substr($s,0,100);
//Trim
$u=preg_replace('/^(.*).\s\w*$/','${1}',$t);
//Output
echo $u;
