由 Program 上的角度來看

modules/field/modules/text/text.module

text_summary($text, $format = NULL, $size = NULL)

  $size = variable_get('teaser_length', 600); ..............................   // Find where the delimiter is in the body   $delimiter = strpos($text, '<!--break-->'); .............................. 

Parameters

$text The content for which a summary will be generated.

$format The format of the content. If the PHP filter is present and $text contains PHP code, we do not split it up to prevent parse errors. If the line break filter is present then we treat newlines embedded in $text as line breaks. If the htmlcorrector filter is present, it will be run on the generated summary (if different from the incoming $text).

$size The desired character length of the summary. If omitted, the default value will be used. Ignored if the special delimiter is present in $text.

Return value

The generated summary.
