I have database data like text [mydata] some text [otherdata] some more text and I want to replace those [mydata] , [otherdata] with dynamic info such as category title for instance.

So the result of my data would be like:

text Category Title some text Category Desc some more text

instead of

text [mydata] some text [otherdata] some more text

I think that can be happen by preg_replace but not quite sure.

code

View::composer('*', function ($view) 
 $notes = Notes::all();
 foreach($notes as $note)
 $descrip= $note->description;
 

 $view->with('descrip', $descrip);
);

More

So basically $note->description content is this data:

text [mydata] some text [otherdata] some more text

I want to replace those elements by data from categories table.

Any idea?

Update

well i was digging and get code below (useing str_replace) however it has some issues,

View::composer('*', function ($view) 
 //getting categories and pull out the values i want to use as `[....]`
 $catC = Category::all();
 foreach($catC as $catD)
 $meta_title = $catD->title;
 $meta_desc = $catD->meta_description;
 $meta_tags = $catD->meta_tags;
 
 //replace those categories values with element in database `[......]`
 $seotemplates = SeoTemplate::all();
 foreach($seotemplates as $seotemplate)
 $myCustom = str_replace_array('[cattitle]', [$meta_title, $meta_desc, $meta_tags], $seotemplate->categories_desc_template);
 

 $view->with('myCustom', $myCustom);
 );

Issues

1. I can only get [cattitle] but what about [catmeta] & [cattags]?


2. 
   $meta_title will always return first value from categories table (for example if i'm visiting HP category page it return ACER as [cattitle] or any other category pages i visit. It's always ACER

Update 2

I solved the issue 1 of my first update but still issue 2 remained, here is updated code

View::composer('*', function ($view) 
 //categories
 $catC = Category::all();
 $catD = ;
 foreach($catC as $catD)
 $catD = [
 $cattitle = $catD->title,
 $catmeta = $catD->meta_tags,
 $catdesc = $catD->meta_description
 ];
 
 $a1 = array("[cattitle]","[catmeta]","[catdesc]");

 $seotemplates = SeoTemplate::all();
 foreach($seotemplates as $seotemplate)
 $myCustom = str_replace($a1, $catD, $seotemplate->categories_desc_template);
 

 $view->with('myCustom', $myCustom);
);

Current issue:

2. 
   $meta_title will always return first value from categories table (for example if i'm visiting HP category page it return ACER as
   [cattitle] or any other category pages i visit. It's always ACER

I see a couple of issues with your code that I think will help with getting the solution that you are after.

First like mentioned by @hktang said in his comment you are duplicating your variables and then assigning it's value over and over again instead of adding to it. Try this:

$catE = ;
foreach($catC as $catD)
 $catE = [
 $cattitle = $catD->title,
 $catmeta = $catD->meta_tags,
 $catdesc = $catD->meta_description
 ];

Second you are also resetting the value of $myCustom with each loop of the for each. Try this:

$myCustom = 
foreach($seotemplates as $seotemplate)
 $myCustom = str_replace($a1, $catE, $seotemplate->categories_desc_template);

This should result in you getting an array of seotemplates with the values replaced but I have not testing this.
