I have an array thusly
$main_array = [
["image" => "james.jpg", "name" => "james", "tag" => "spacey, wavy"],
["image" => "ned.jpg", "name" => "ned", "tag" => "bright"]
["image" => "helen.jpg", "name" => "helen", "tag" => "wavy, bright"]
]
I use a foreach
to echo some HTML based on the value of tag
. Something like this
foreach($main_array as $key => $array) {
if ($array['tag'] == "bright") {
echo '<p>'.$array['name'].' '.$array['image'].' '.$array['tag'].'</p>';
}
}
This only outputs "ned" as matching the tag "bright". But it should output "helen" too. Similarly:
foreach($main_array as $key => $array) {
if ($array['tag'] == "wavy") {
echo '<p>'.$array['name'].' '.$array['image'].' '.$array['tag'].'</p>';
}
}
Should output "james" and "helen". What kind of function do I need to achieve the desired result?

You cant do it directly, because it return key with values in string. Below are the working code.
<?php
$main_array = [
["image" => "james.jpg", "name" => "james", "tag" => "spacey, wavy"],
["image" => "ned.jpg", "name" => "ned", "tag" => "bright"],
["image" => "helen.jpg", "name" => "helen", "tag" => "wavy, bright"]
];
foreach($main_array as $key => $array) {
$str_arr = explode (", ", $array['tag']);
foreach ($str_arr as $key2 => $array2) {
if ($array2 == "wavy") {
echo '<p>'.$array['name'].' '.$array['image'].' '.$array['tag'].'</p>';
}
}
}
?>

When checking an item in a list of items, you can use explode()
to split it into parts (I've used split by ", "
as each item seems to have a space as well) and then use in_array()
to check if it is in the list...
if (in_array("bright", explode( ", ", $array['tag']))) {
