Helpers Useful string manipulations

CakePHP comes with a bunch of useful helpers and components that provide convenient tools for processing and manipulating data. These helpers are significant not only for the framework user, but can also be of great help to someone who writes PHP applications without using CakePHP.


Here are some examples:

Numberhelper

Number helper contains powerful functions for manipulating numbers.
')
precision ()

precision () returns a number formatted with a precision level. For example:

  echo $ number-> precision (25.02558, 3);
 // displays
 25.026 

toReadableSize ()

This function takes the file size as an argument and returns a well-formatted string indicating the size in bytes, Kb, Mb, GB and TB. For example:

  echo $ number-> toReadableSize (2502558);
 // displays
 2.39 MB 

Other Numer helper functions:
toPercentage () : Formats a number in percentages.
format () : Formats a number in a monetary format.
currency () : Formats a number in a currency format signed by a currency sign.

See the file cake / libs / view / helpers / number.php for a complete list of Number Helper functions and their uses.

Texthelper

Text helper contains useful functions for manipulating text strings.

highlight ()

Highlights the specified phrase in the text. For example:

  echo $ text-> highlight ("Word example will be highlighted", "example");
 // displays 

Will be highlighted
* (example will be highlighted. Habr does not allow it to show)

Note: you must define a style for the “highlight” class in your CSS. For example:
.highlight {background: # FFFF00;}

stripLinks ()

Removes all links (<a href = ....) From the given text. Example:

  echo $ text-> stripLinks ('Dont show the clickable link on <a href="http://www.givebackindia.com"> Online Charity Mall </a>');
 // displays

autoLinkUrls ()

Adds links (<a href = ....) In specified text in which strings begin with http: // and.

autoLinkEmails ()

Adds email links (<a href = ”mailto: ....) In the specified text.

truncate ()

Cuts the string to the length specified in the second parameter and replaces the last characters. Takes care of HTML tags and encoding.

For example:

  echo $ text-> truncate ("), 50);
 // outputs
 Cuts a string of the second arg ... 

excerpt ()

Creates an excerpt from the text around the search phrase with a length of a certain radius and adds an ending.
