PHP Tutorial – Breaking A Foreach Loop

This morning while studying, I remembered how I figured out how to stop / break a PHP foreach loop after a certain number while coding a pet project of mine. I decided to share a short tutorial explaining how this is accomplished and I just hope somebody if not today, will find it useful.

Firstly, let’s create an Array.


$array = array("NIG" => "Nigeria", "AFR" => "Africa", "LAG" => "Lagos", "ABJ" => "Abuja" );

Next, create two variables set with a counter and number to display argument.
```
 $count = 0;
$max = 3;
```

Here is the Foreach loop


foreach ($array as $key => $value) {
$count++; // increment the counter by 1 

printf("%s is the acronym for %s
", $key, $value ); // display the loop content

if ($count == $max) break; // stop looping if $max value is reached
}

You can always change the value of $max to the number of display content.

Below is the full code.


< ?php
$array = array("NIG" => "Nigeria", "AFR" => "Africa", "LAG" => "Lagos", "ABJ" => "Abuja" ); 

$count = 0;
$max = 3;

foreach ($array as $key => $value) {
$count++;
printf("%s is the acronym for %s
", $key, $value );

if ($count == $max) break; // stop looping if $max value is reached
}

?>

Below is the output of the code when run;

NIG is the acronym for Nigeria
AFR is the acronym for Africa
LAG is the acronym for Lagos
