I know how to use the substr function but this will happy end a string halfway through a word. I want the string to end at the end of a word how would I go about doing this? Would it involve regular expression? Any help very much appreciated.

This is what I have so far. Just the SubStr...

echo substr("$body",0,260);

Cheers

substr($body, 0, strpos($body, ' ', 260))

It could be done with a regex, something like this will get up to 260 characters from the start of string up to a word boundary:

$line=$body;
if (preg_match('/^.{1,260}\b/s', $body, $match))
{ $line=$match[0];
}

Alternatively, you could maybe use the wordwrap function to break your $body into lines, then just extract the first line.

You can try this:

 $s = substr($string, 0, 261); $result = substr($s, 0, strrpos($s, ' '));

You could do this: Find the first space from the 260th character on and use that as the crop mark:

$pos = strpos($body, ' ', 260);
if ($pos !== false) { echo substr($body, 0, $pos);
}

wordwrap and explode then first array element is you want$wr=wordwrap($text,20,':'); $strs=explode(":",$wr); $strs[0]

I use this solution:

$maxlength = 50;
substr($name, 0, ($spos = strpos($name, ' ', $lcount = count($name) > $maxlength ? $lcount : $maxlength)) ? $spos : $lcount );

Or inline:

substr($name, 0, ($spos = strpos($name, ' ', $lcount = count($name) > 50 ? $lcount : 50)) ? $spos : $lcount );

function substr_word($body,$maxlength){ if (strlen($body)<$maxlength) return $body; $body = substr($body, 0, $maxlength); $rpos = strrpos($body,' '); if ($rpos>0) $body = substr($body, 0, $rpos); return $body;
}

What about this?

/** * @param string $text * @param int $limit * @return string */
public function extractUncutPhrase($text, $limit)
{ $delimiters = [',',' ']; $marks = ['!','?','.']; $phrase = substr($text, 0, $limit); $nextSymbol = substr($text, $limit, 1); // Equal to original if ($phrase == $text) { return $phrase; } // If ends with delimiter if (in_array($nextSymbol, $delimiters)) { return $phrase; } // If ends with mark if (in_array($nextSymbol, $marks)) { return $phrase.$nextSymbol; } $parts = explode(' ', $phrase); array_pop($parts); return implode(' ', $parts); // Additioanally you may add ' ...' here.
}

Tests:

public function testExtractUncutPhrase()
{ $stringUtils = new StringUtils(); $text = 'infant ton-gue could make of both names nothing'; $phrase = 'infant'; $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 11)); $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 12)); $text = 'infant tongue5'; $phrase = 'infant'; $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 13)); $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 11)); $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 7));
}
public function testExtractUncutPhraseEndsWithDelimiter()
{ $stringUtils = new StringUtils(); $text = 'infant tongue '; $phrase = 'infant tongue'; $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 13)); $text = 'infant tongue,'; $phrase = 'infant tongue'; $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 13));
}
public function testExtractUncutPhraseIsSentence()
{ $stringUtils = new StringUtils(); $text = 'infant tongue!'; $phrase = 'infant tongue!'; $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 14)); $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 100)); $text = 'infant tongue!'; $phrase = 'infant tongue!'; $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 13)); $text = 'infant tongue.'; $phrase = 'infant tongue.'; $this->assertEquals($phrase, $stringUtils->extractUncutPhrase($text, 13));
}

$pos = strpos($body, $wordfind);
echo substr($body,0, (($pos)?$pos:260));

public function Strip_text($data, $size, $lastString = ""){ $data = strip_tags($data); if(mb_strlen($data, 'utf-8') > $size){ $result = mb_substr($data,0,mb_strpos($data,' ',$size,'utf-8'),'utf-8'); if(mb_strlen($result, 'utf-8') <= 0){ $result = mb_substr($data,0,$size,'utf-8'); $result = mb_substr($result, 0, mb_strrpos($result, ' ','utf-8'),'utf-8');; } if(strlen($lastString) > 0) { $result .= $lastString; } }else{ $result = $data; } return $result;
}

Pass the string into funtion Strip_text("Long text with html tag or without html tag", 15)Then this function will return the first 15 character from the html string without html tags. When string less than 15 character then return the full string other wise it will return the 15 character with $lastString parameter string.

Example:

Strip_text("<p>vijayDhanasekaran</p>", 5)

Result: vijay

Strip_text("<h1>vijayDhanasekaran<h1>",5,"***....")

Result: vijay***....

Try This Function..

<?php
/** * trims text to a space then adds ellipses if desired * @param string $input text to trim * @param int $length in characters to trim to * @param bool $ellipses if ellipses (...) are to be added * @param bool $strip_html if html tags are to be stripped * @param bool $strip_style if css style are to be stripped * @return string */
function trim_text($input, $length, $ellipses = true, $strip_tag = true,$strip_style = true) { //strip tags, if desired if ($strip_tag) { $input = strip_tags($input); } //strip tags, if desired if ($strip_style) { $input = preg_replace('/(<[^>]+)/i', '$1',$input); } if($length=='full') { $trimmed_text=$input; } else { //no need to trim, already shorter than trim length if (strlen($input) <= $length) { return $input; } //find last space within length $last_space = strrpos(substr($input, 0, $length), ' '); $trimmed_text = substr($input, 0, $last_space); //add ellipses (...) if ($ellipses) { $trimmed_text .= '...'; } } return $trimmed_text;
}
?>
