mb_strimwidth — Get truncated string with specified width
Truncates string str to specified width.
The string being decoded.
The start position offset. Number of characters from the beginning of string. (First character is 0)
The width of the desired trim.
A string that is added to the end of string when string is truncated.
Der encoding Parameter legt das Zeichenencoding fest. Wird er nicht übergeben so wird das interne Zeichenencoding genutzt.
The truncated string. If trimmarker is set, trimmarker is appended to the return value.
Beispiel #1 mb_strimwidth() example
<?php
echo mb_strimwidth("Hello World", 0, 10, "...");
// outputs Hello W...
?>
<?php
function strimwidthCenter( $value, $length = 40 ) {
$valueEncoding = mb_detect_encoding( $value, 'auto', true );
if ( $length >= mb_strwidth( $value, $valueEncoding ) ) {
return $value;
}
$limited = '';
$firstWidth = ceil( $length/2 );
$secondStart = mb_strwidth( $value, $valueEncoding ) - ( $length - $firstWidth );
$secondWidth = $length - $firstWidth +1;
$limited = mb_strimwidth( $value, 0, $firstWidth, '...', $valueEncoding ) . mb_substr( $value, $secondStart, $secondWidth, $valueEncoding );
return $limited;
}
?>
While having the option to append a string to the end is nice, you can run into the problem of having a space between the append if the width is truncated after a space. I find something like this to be more attractive in the output, although messy in the code.
rtrim(mb_strimwidth($string, 0, 24))."..."
