Get first 100 characters from string, respecting full words

Viewed 321 times

I have asked a similar question here before, but I need to know if this little tweak is possible. I want to shorten a string to 100 characters and use $small = substr($big, 0, 100); to do so. However, this just takes the first 100 characters and doesn't care whether it breaks up a word or not.

Is there any way to take up to the first 100 characters of a string but make sure you don't break a word?

Example:

$big = "This is a sentence that has more than 100 characters in it, and I want to return a string of only full words that is no more than 100 characters!"

$small = some_function($big);

echo $small;

// OUTPUT: "This is a sentence that has more than 100 characters in it, and I want to return a string of only"

Is there a way to do this using PHP?

All you need to do is use:

$pos=strpos($content, ' ', 200);
substr($content,0,$pos );

You need a Ajax call to pass the JS value into php variable

JS Code will be (your js file)

var jsString="hello";
$.ajax({
    url: "ajax.php",
    type: "post",
    data: jsString
});

And in ajax.php (your php file) code will be

$phpString = $_POST['data'];     // assign hello to phpString

For single-byte strings (e.g. US-ASCII, ISO 8859 family, etc.) use substr and for multi-byte strings (e.g. UTF-8, UTF-16, etc.) use mb_substr:

// singlebyte strings
$result = substr($myStr, 0, 5);
// multibyte strings
$result = mb_substr($myStr, 0, 5);

>>> text = 'lipsum'
>>> text[3:]
'sum'

See the official documentation on strings for more information and this SO answer for a concise summary of the notation.
