Check if a json array value exits on php or not - php

Question

Hi everyone
I´m making a project where i need to check if a 'x' value, which is being defined on a PHP variable, is founded or not inside the JSON steamid array...
Here is a example of how JSON structure looks like:
{
"users": [
{
"steamid": "[X:X:XXXXXXXXX]",
"teamspeakid": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
"nicknames": [
"XXXXXXXXX"
],
"addresses": [
"XX.XX.XXX.XX"
]
},
{
"steamid": "[Y:Y:YYYYYYYYY]",
"teamspeakid": "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYY",
"nicknames": [
"YYYYYYYYY"
],
"addresses": [
"YY.YY.YYY.YY"
]
},
{
"steamid": "[Z:Z:ZZZZZZZZZ]",
"teamspeakid": "ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ",
"nicknames": [
"ZZZZZZZZZ"
],
"addresses": [
"ZZ.ZZ.ZZZ.ZZ"
]
}
]}
The PHP function structure that I have on my mind is similar to this:
if (x value is founded on json->users steamid array) {
$verified = 1;
$teamspeakid = the founded steamid->teamspeakid;
$nicknames = the founded steamid->nicknames;
$addresses = the founded steamid->addresses;
} elseif (steamid value is not founded on json array) {
$verified = 0;
}
I hope you can help me :-)

You need to decode the json array then use strpos to check the string or character exists or not.Do like below:
$jsonarr='{
"users": [
{
"steamid": "[X:X:XXXXXXXXX]",
"teamspeakid": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
"nicknames": [
"XXXXXXXXX"
],
"addresses": [
"XX.XX.XXX.XX"
]
},
{
"steamid": "[Y:Y:YYYYYYYYY]",
"teamspeakid": "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYY",
"nicknames": [
"YYYYYYYYY"
],
"addresses": [
"YY.YY.YYY.YY"
]
},
{
"steamid": "[Z:Z:ZZZZZZZZZ]",
"teamspeakid": "ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ",
"nicknames": [
"ZZZZZZZZZ"
],
"addresses": [
"ZZ.ZZ.ZZZ.ZZ"
]
}
]}';
$arr=json_decode($jsonarr,true);
$searchstring='X';
foreach($arr['users'] as $key=>$value){
if (strpos($value['steamid'], $searchstring) !== false) {
$verified = 1;
}else{
$verified = 0;
}
}
or
if(array_search($searchstring, array_column($arr['users'], 'steamid')!== false) {
$verified = 1;
}else{
$verified = 0;
}
