indexof数组js等效于php [duplicate]

Question

This question already has an answer here:

• php index of item 3 answers

$solutionsMap = [];
$score = 655536;

in js I have if(solutionsMap.indexOf(score) === -1).

I need an equivalent in php for solutionsMap.indexOf(score) === -1. I tried array_search(), strpos(), but with errors.

I searched before this question, but I still got errors.

</div>

Answer 1

Use the array_search() function:

$k = array_search('text', $array);

For example:

$solutionsMap = array('655536' => 'score', 1 => 'other');

$key = array_search('score', $solutionsMap); // $key = 655536;

echo $key;

Output:

655536

Try it here.
