I have an array of arrays as such below and I want to check if the [avs_id] contains a substring "a_b_c". How to do this in php?
Array
(
[id] => 10003
[avs_id] => a_b_c_3248
)
Array
(
[id] => 10003
[avs_id] => d_e_f_3248
)
You can use array_filter():
$src = 'a_b_c';
$result = array_filter
(
$array,
function( $row ) use( $src )
{
return (strpos( $row['avs_id'], $src ) !== False);
}
);
The result maintain original keys, so you can directly retrieve item(s) matching substring.
If you want only check if substring exists, or the number of items having substring, use this:
$totalMatches = count( $result );
Loop through your array and test for the string in the specific element of your array with strpos as in the example code below.
foreach($yourMainArray as $arrayItem){
if (strpos($arrayItem['avs_id'], 'a_b_c') !== false) {
echo 'true';
}
}
A loop may be more ideal but if you know what array index the string is in that you are after:
$arr = array('id'=>'10003', 'avs_id'=>'a_b_c_3248');
if (strpos($arr['avs_id'], 'a_b_c') !== false) {
echo 'string is in avs_id';
}
You can use :
foreach($yourArray as $arrayItem){
if (strpos($arrayItem['avs_id'], 'a_b_c') !== false) {
//return true : code here
}
}
