Search for string part per TypoScript

To search a string part (needle) in string (haystack), you can easily use the PHP strpos function. But this function doesn’t exist in TypoScript.

The following TypoScript return true if the needle is found in the haystack. This can be used in an if condition.

The above COA will return true if http is found in the header_link field. I used this to add ATagParams for external link, in assumption that link with http(s) is an external link.

Automatically apply PSR-2 coding style

*UPDATE*

In version 2 of php_cs_fixer some parameters and rules are renamed. Upgrade guide can be see on their Github page. This how-to is accordingly updated.


Applying PSR-2 coding style manually is really no fun and wasting time. A short visit in Github and there’s a tool which detects and fixes the coding style. The tool is called php-cs-fixer.

I’ll show you how to get the tool and use it to easily reformat all PHP file in project.

Fail downloading file on Android

How hard is it, to write a PHP script to allow user to download a file? really easy, one would say. Just send the appropriate HTTP header and echo the file content.

What does happen here?

[PHP] Removing duplicate in an array… really fast

Let’s imagine you have a huge array, with say couple ten thousands of elements and you want to remove any duplicates entries in this array. As PHP programmer you’ll be thinking of array_unique. For a “small” sized array and one dimensional array this one does the trick.

I have some nice snippets which cover multi dimensional and/or huge sized array.

First: you have a huge, one dimensional array.

This one works only on one dimensional array. The key of the last element will be preserved and the keys are not sorted

Second: for a huge, multi dimensional array
