Here is my fourth foreach loop where I get same error like mentioned on my previous post.
Notice: Array to string conversion in /storage/emulated/0/htdocs/template_notes/Bot_Template.php on line 149
Array
I checked with var_dump.
Both $ignored_links and $harvested_links are arrays.
Hence, I never should've got those errors.
Here is my full code so far.
Run it through on your localhost and see for yourself why you get the error.
Note the var_dump() I have commented out.
Run it like that first as a test and see if you can reproduce the two errors or not that I mentioned above.
After that, run it by uncommenting the var_dump and see for yourself why you go in an infinite loop.
Puzzling!
I tested it on my localhost.
It only has 3 files.
1.html
2.html
3.html
Each of these three links only link to each other.
Hence the crawler ends it's crawl after crawling these three links. That is providing the var_dump codes at the bottom of the code is commented-out. Test and see for yourselves.
However, when you uncomment the var_dump codes at the bottom of my crawler's source code, the car_dump infinitely starts generating code as if gone in a loop. Why is that ?
Big mystery for two nights now!
It is a simple webcrawler.
You submit your URL.
It lists in: $links_to_visit = array().
It navigates to the first array value (your submitted link) and scrapes all links found on the initially crawled page.
Scrapes to array:
$scraped_links[].
It checks each Scraped link for duplicates.
Meaning, it hecks if it has already been Scraped or not.
It checks against the arrays:
$links_to_visit[].
$visited_links[].
We don't want to list the same link more than once on the first array. Else, the crawler will be crawling the same link more than once.
And we don't want to list the same link more than once either on the second link. Else, the crawler will be crawling links already crawled.
Scraped links that pass this duplicate entry test, get listed in array $links_to_visit[] for crawling.
When crawler moves onto the next link in the crawling list ($links_to_visit[]), it lists the currently crawled link to the array $visited_links[].
The same steps repeat on the second page.
And so on for all the remaining pages.
You will need the simplehtmldom to test my code.

@NogDog#1628021
NogDog,
How am I trying to echo an array ?
I am trying to echo a value of an array.
Look, $harvested_links is an array. Not trying to echo that whole array. $harvested_link is a value of the array. Trying to echo that. Note the plural and singular mentioned in the two variables.
How am I trying to echo the array above ?@viakgroup#1628029
I shouldn't use foreach loop on an empty array value ?
And just how am I supposed to know if a value is empty or not without using the foreach loop ?
To determine if a value is empty or not, I would use foreach loop like so:
1
2.
3.
4.
5.
Not sure if the last two will work or not as I don't usually use them.
My point is, I have to use the foreach loop to findout if the value is empty or not.
Or you suggest I use other loops instead like DoWhile, For, etc. ?
@NogDog ,
Can you check my 5 codes on my last post and rank them according to your own choices where top best on top and least on bottom ?
My own rankings:
3

Folks,
It seems in all my 7 samples, I used a colon than a semi colon. Typo. Opened this thread via my smart fone. Hard to type on fones. Plus nowadays I see fuzzy texts. Will need glasses. @NogDog ,
I replied to your misunderstanding. You said I was trying to echo an array. I corrected you that I was trying to echo a value of an array. Not the whole array. And so shouldn't have got the error
Do check my code again and see for yourself.@Sempervivum
Why do you think I getting the error when trying to echo a value of an array via the foreach loop ?I viewed the code in your 1st and 2nd posting. The note says that you are trying to echo an array and therefore an array to string conversion was performed. Obviously $ignored_link is an array. Verify this by outputting it by var_dump: @Sempervivum#1628650
No $ignored_link was not an array.
$ignored_links was.
Note the singular and plural here.
Problem was, when I defined the array $ignored_links and $harvested_links, I made mistakes. Hence the error. Mistake was this:
Note the []. They not supposed to be there.
Just spotted this error now.
Thread maybe closed.
I did 😀
This code:
` is an **array**.@Sempervivum#1628652
Here is the full source code. Run it on localhost and tell me how $ignored_link and $harvested_link became arrays.
@NogDog
You try too. It should satisfy your curiosity how I am building a webcrawler.
Folks,
Do you see anything wrong with this foreach loop ?
If not, then why I get error ?
I got 4 foreach loops. First two are ok. Last two causing this same type of error.
Following is my third foreach loop where I get error.
[code]
if(ISSET($ignored_links))
{
$ignored_links_count = count($ignored_links);
echo ‘Ignored Links Count: ‘ .$ignored_links_count; echo ‘<br>’;
}
echo ‘Ignored Links: ‘; echo ‘<br>’;
if($ignored_links_count>=1)
{
//On this Crawling S ssion, atleast one Scraped Link has been discarded.
foreach($ignored_links as $ignored_link)
{
//Display a List of all Discarded Links.
echo __LINE__; echo ‘<br>’;
echo $ignored_link; echo ‘<br>’; //”Notice Array to String Conversion” error on this line.
echo ‘<br>’;
}
}

To determine if a value is empty or not, I would use foreach loop like so:

echo $value:

2.

{
if($value)=='NULL')
echo $value:
}
5.
<i>
</i>foreach($array as $value)
{
if(!empty($value))
echo $value:

Not sure if the last two will work or not as I don't usually use them.
