Introduction to variable operators in the Smarty Template

Capitalize [uppercase letters], for example: {$ smarty. get. name | capitalize}

Count_characters [count characters], for example: {$ smarty. get. name | count_characters}

Cat [connection string], example: {$ smarty. get. name | cat: 'Welcome to www.phpernote.com '}. connect two variables, for example, {$ smarty. get. name | cat: $ smarty. get. password}

Count_paragraphs [calculates the number of paragraphs], for example: {$ smarty. get. name | count_characters}
 
Count_sentences [calculates the number of periods], for example: {$ smarty. get. name | count_sentences}

Count_words [count words], example: {$ smarty. get. name | count_words}

Date_format [time format], for example: {$ smarty. server. request_time | date_format: "% Y-% m-% d % H: % M: % S"} or {$ smarty. now | date_format: "% Y-% m-% d % H: % M: % S"}. display format: 11:01:21

Default [default], example: {$ smarty. get. name | default: 'phpernote. com '}, which indicates that phpernote.com is used to replace the value when the name parameter is not accepted or the received name parameter value is null.
 
Escape [transcoding], example: {$ smarty. get. name | escape: 'URL '}?

Indent [indent], for example: {$ smarty. get. name | indent: 10: ''}, indent the first line of the paragraph. The example here is indented by ten characters in space. The function is similar to text-indent in css.

Lower [lower case], example: {$ smarty. get. name | lower}

Upper [upper case], example: {$ smarty. get. name | upper}

Nl2br [replace \ n (linefeed) in the variable
], For example: {$ smarty. get. name | nl2br}

Regex_replace [regular expression replacement], for example: {$ smarty. get. name | replace: "/[\ r \ t \ n]/": "phpernote.com"}, replace the regular content in the variable with the specified content.

Replace [replace], for example: {$ smarty. get. name | replace: "baidu.com": "phpernote.com"}. replace the content required in the variable with the specified content. In this example, replace all baidu.com in the variable with phpernote.com.

Spacify [inserted blank], for example: {$ smarty. get. name | spacify: "^"}, inserts the specified content between the variable and character, including spaces.

String_format [string formatting], for example: {$ smarty. get. namestring_format: "% d"}. this operation is to format the content in the variable. the formatting parameter is similar to the printf of php.

Strip [remove (extra space)], example: {$ smarty. get. name | strip: ""}. if the first parameter exists, the space is replaced with the specified content. In this example, the space is replaced "";
 
Strip_tags [remove html tags], example: {$ smarty. get. name | strip_tags}

Truncate [truncate], for example: {$ smarty. get. name | truncate: 10 :'... '}. The example indicates 10 characters are intercepted. the excess part is "... "Replace. if the second parameter is null, the excess part is omitted directly.

Wordwrap [row width constraint], for example: {$ smarty. get. name | wordwrap: 30: "\ n": true}, force line feed of content beyond the specified length
