how to break foreach loop - array index

Question

My array which is dynamic, formed as

$exam = explode(',',$row['exam']);

For example result is:

$exam = array("First-Term","Second-Term", "Third-Term");

We can get index and value as this

foreach (array_values($exam) as $i => $value) {
  echo "$i: $valuen";
  echo "//And its mark";
}

But, how can I break loop to each index. I have to fetch as follow

First-Term
//And its mark

Second-Term
// And its mark

Third-Term
// And its mark

But while using foreach loop, I am getting

First-Term
Second-Term
Third-Term
//And its mark
//And its mark
//And its mark

How to break loop to each index, after that we use same code in every index. I'm simply try to assign each marks to each term

$exam[0]{
    //here is $value
    //rest of the code, same code to every index
}

$exam[1]{
    //here is $value
    //rest of the code, same code to every index
}

$exam[2]{
    //here is $value
    //rest of the code, same code to every index
}

$exam[...]{
    //
}

Can you give a little more background to what you want the code to do? I don't understand why you would want to beak out of the loop at each index, if you want to execute the same piece of code for each item in the $exam array. — Marijn van Vliet

...wait, do you mean that there is some code that is unique for each term, and some code that is the same for all terms? — Marijn van Vliet

@MarijnvanVliet, same code for every term. Please understand as this. I have to fetch First term -> Math, Second term-> Math, But I am getting First term Second Term -> Math Math — Dipak

@AnandHmt, can you give some real example instead of // code,// here? From a first look, it just looks like echoing info with extra line breaks. — Rafael

You should make two arrays for team and marks and then parse these two arrays in the same foreach loop like this

$team = array('a', 'b', 'c', 'd' );
$marks = array('1', '2', '3', '4' );

foreach(array_combine($team, $marks) as $t => $m) {
    echo $t . "<br>" .$m . "<br><br>"; //$t for team and m for marks
    echo "<br/>";
}

In this way you can parse your different data in a paralell way

careful! if($i = 0) will assign 0 to $i. Did you mean if($i == 0)?

@MarijnvanVliet Ohh. Sorry, It was a typo error. I was in rush

@ZainFarooq, array is dynamic, so it is not possible to apply rule to each index. how to address this issue ?

Zain Farooq Over a year ago

But in question you made a static array

Marijn van Vliet Over a year ago

but now $i == $counter will always evaluate to TRUE. Why have the if-statement in the first place?

From the looks of what you are doing, you are using two foreach loops with different output...

This one:

$exam = array("First-Term","Second-Term", "Third-Term");

foreach (array_values($exam) as $i => $value) {
    echo "{$value}<br>";
    echo "// And its mark<br><br>";
}

Will output this:

First-Term
//And its mark

Second-Term
// And its mark

Third-Term
// And its mark

While this loop:

$exam = array("First-Term","Second-Term", "Third-Term");

foreach (array_values($exam) as $i => $value) {
    echo "{$value}<br>";
}
foreach (array_values($exam) as $i => $value) {
    echo "// And its mark<br>";
}

Will output this:

First-Term
Second-Term
Third-Term
// And its mark
// And its mark
// And its mark

Will update this answer once I have more details. Code tested: https://3v4l.org/RDvYN

I would build an array with everything in place and then start to display it:

$exam = array("First-Term","Second-Term", "Third-Term");
$marks = array(1, 2, 3);

$result = array();
foreach (array_values($exam) as $idx => $value) {
    $result[] = array(
         "exam" => $value,
         "mark" => $marks[$idx]
    );
}

foreach ($result as $value) {
    echo $value['exam'] . "\n";
    echo $value['mark'] . "\n\n";
}

Click on "Run code snippet". This tool is designed for HTML/CSS/Javascript statements only.

OK, of course it won't work that way. Just run it on your machine with php.

Rafael Over a year ago

If the code is not supposed to work in a code snippet, maybe it should not be in a code snippet, maybe?
