php—Smarty-3 （20）

1. Notes

*Annotation content*

Html comments are displayed in client source files

Smarty comments will not be sent to the client

Smarty’s comments are mainly for template designers to see

2. Variables in templates

l distributed by php file

1) Ordinary variables

2) Array variable

3) Object variables

Program code:

Template code:

1 Assigned by configuration file

Profile:

Template code:

2 Create in template file

3. Variable regulator

The variable regulator is mainly used to format variables.

Grammar:

{$var|Regulator:parameter1:parameter2:……}

l {$var|capitalize} : Capitalize the first letter

l {$var|count_characters:true}: Calculate string length true: Calculate spaces Default: false

l {$var|cat:var2}: connection string

l {$var|count_paragraphs}: Count the number of paragraphs

l {$var|count_sentences}: Count the number of sentences

l {$var|count_words}: Count the number of words

l {$var|date_format:”%H%M%S”}: formatting time

l {$var|default:”value”}: Default value

l {$var|escape}: transcoding

l {$var|indent:10:”*”}: indent

l {$var|lower}: lowercase

l {$var|nl2br}: Convert file line breaks to web page line breaks

l {$var|regex_replace:”/[tn]/”:” “}: Regular replacement

l {$var|replace:"aa":"bb"} : String replacement

l {$var|spacify:”^^”}: insert blank

l {$var|string_format:”%d”} : String formatting

l {$var|strip} : Remove consecutive spaces

l {$var|strip_tags}: Remove html tags

l {$var|truncate:30:”…”}: Truncation string

l {$var|upper}: Convert to uppercase

l {$var|wordwrap:30:”n”} : Line width constraint

Combined use of variable regulators

{$var|capitalize|truncate:30:”…”|replace:”aa”:”bb”}

1) Capitalize the first letter of the $var variable

2) Then intercept 30 strings from $var

3) Then replace aa in the intercepted content with bb

The above introduces php-Smarty-3 (20), including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
