Limit this PHP foreach statement to just 5 loops - php

Question

How could I limit this foraech statement to just 5 loops? I think I should just use Break but I'm not sure where to put it.
<?php if(!empty($locations)): foreach($locations as $location): ?>
<?php if(empty($location["title"])) continue; ?>
<li>
<a href="<?php esc_attr_e($url.$glue.http_build_query($location["query"])) ?>">
<?php esc_html_e($location["title"]) ?>
</a>
<?php if($param->count): ?>
<div class="wpjb-widget-item-count">
<div class="wpjb-widget-item-num"><?php echo intval($location["count"]) ?></div>
</div>
<?php endif; ?>
</li>
<?php endforeach; ?>

Answer 1

You can use array_slice() first to get a new array with no more than 5 elements.
$locations = array_slice($locations, 0, 5);
Then everything unchanged.

Answer 2

There are three methods:
Method 1: foreach with a counter var
$counter = 1;
foreach($locations as $location) {
// use $location here
if($counter++ == 5) {
break;
}
}
Method 2: foreach using $key=>$val
foreach($locations as $key=>$val) {
// Your content goes here
if($key === 4) {
break;
}
}
Method 3: for loop
for($i = 0; $i < 5; $i++) {
// Use $locations[$i] here and do something with it
}

Answer 3

Using a counter variable into your loop you can control/limit to any number.
Example:
$counter = 0;
foreach($locations as $location):
if($counter++ == 5):
break;
// Your other content goes here
endif;
endforeach;

Answer 4

Add a variable ... increment it each iteration ... after reach 5 just break loop.
<?php $i = 1;?>
<?php if(!empty($locations)): foreach($locations as $location): ?>
<?php if(empty($location["title"])) continue; ?>
<li>
<a href="<?php esc_attr_e($url.$glue.http_build_query($location["query"])) ?>">
<?php esc_html_e($location["title"]) ?>
</a>
<?php if($param->count): ?>
<div class="wpjb-widget-item-count">
<div class="wpjb-widget-item-num"><?php echo intval($location["count"]) ?></div>
</div>
<?php endif; ?>
</li>
<?php if ($i++ == 5) break; ?>
<?php endforeach; ?>

Answer 5

You can use for():
<?php if(!empty($locations)):
for($i=0; $i<5; $i++) {
$location = $locations[$i];
<?php if(empty($locations["title"])) continue; ?>
<li>
<a href="<?php esc_attr_e($url.$glue.http_build_query($location["query"])) ?>">
<?php esc_html_e($location["title"]) ?>
</a>
<?php if($param->count): ?>
<div class="wpjb-widget-item-count">
<div class="wpjb-widget-item-num"><?php echo intval($location["count"]) ?></div>
</div>
<?php endif; ?>
</li>
}
