Accessing specific element - DOM PHP HTML
I am using the simple html DOM with PHP 7.0.
If i need to get at the pClassLarge value but set variable for each one, how would I do this??
<div class="outerClass"><p class="pClassTop">Subject One</p><p class="pClassLarge">I need this!!</p></div>
<div class="outerClass"><p class="pClassTop">Subject Two</p><p class="pClassLarge">I also need this value!!</p></div>
<div class="outerClass"><p class="pClassTop">Subject Three</p><p class="pClassLarge">And lastly this one too!!</p></div>
This code below is totally wrong, but I'm trying to express my intentions... Each pClassTop is a different header and each pClassLarge within is a different value but I need to be sure I am isolating them.
$var1=(the value for pClassLarge within the pClass top IF <p>Subject One</p>);
$var2=(the value for pClassLarge within the pClass top IF <p>Subject Two</p>);
$var3=(the value for pClassLarge within the pClass top IF <p>Subject Three</p>);
Please excuse the rough code for the variables, as I have no idea where to begin, so I'm just trying to show the concept for now. I am able to isolate by class, but then I'm just left with a bunch of digits that I have no idea what they belong to, so I need to set the variables for pClassLarge based on the subject contained within the pClassTop.

<script>
$(document).ready(function(){
$('.pClassLarge').each(function(i, obj) {
x = $(obj).html();
alert(x);//this is the value of div
alert(i);//this the index
});
});
</script>
This does work, but its over my head. I'm really new at javascript and was hoping to figure out how to do this in php.
Basically I understand its setting the value but its overwriting the old one. I would need to store it as 3 different variables as in the question and I dont know what to do in javascript to go any further with this. Any other ideas?

From where do you get these tags generated from?
or "I need this!!" : Do you get this value from a page generated using php code or is it a static html code?

Its an html page and this example shows that basically each <div> contains an inner <p>. So in every case I need to assign by figuring out what the content of the div actually is then set the variable to the value of the inner <p> within the div. For instance...if the <div> has content in it that says, "temperature" the <p>says "96 degrees". Or the <div> says "favorite food" and the <p> says "pizza".
There are only a few fields I need so I can do something like...
if div contents="temperature" set $temperature=<the value of p>
if div contents="favorite food" set $favFood=<the value of p>
Each div class is identical and each p class is identical but by scanning for the value inside the div, I can assign the appropriate variable depending on which div its looking in.

Following is solution to get all values from pClassLarge class:
This will give you array of values.
This will give you array of values.
$html = '<div class="outerClass"><p class="pClassTop">Subject One</p><p class="pClassLarge">I need this!!</p></div>
<div class="outerClass"><p class="pClassTop">Subject Two</p><p class="pClassLarge">I also need this value!!</p></div>
<div class="outerClass"><p class="pClassTop">Subject Three</p><p class="pClassLarge">And lastly this one too!!</p></div>';
preg_match_all('/class="pClassLarge">(.*?)<\/p>/s',$html,$arrayMatches);
$classLargeValues = $arrayMatches[1];
print_r($classLargeValues);
Ray,
This looks like what I need to do, I will play around with it.
To finish I need to loop through and ask what is the value. So for the example above its basically
Field Name = Field Value
$pct[0]=$pcl[0];
$pct[1]=$pcl[1];
$pct[2]=$pcl[2];
Below is conceptually what I'm trying to do with the completed arrays.
if (***$pct array value***==="Subject One"){
$subjectOne="*** the matching value $pcl array***"
}elseif(***$pct array value***==="Subject Two"){
$subjectTwo="*** the matching value $pcl array***"
}elseif(***$pct array value***==="Subject Three"){
$subjectThree="*** the matching value $pcl array***"
}
I'm just not sure on the syntax to do this? Also I loaded an entire html page, not just 3 divs and I did so like this
$html = file_get_html('myHTMLsaveI
It works fine to create the arrays, but is there a reason I should use the <<<EOD thing and if so how do incorporate a file into that such as
The above doesnt work but is it necessary if it works without the EOD thing?
