Method: 1. Use "foreach($arr as $v){}" to traverse the array; 2. Use "if(empty($v)){$i;}else{$i=0; break;}" to determine whether the array value is empty; 3. The loop ends. If the "$i" value is not 0, then the array has a value and is not empty, otherwise it is not empty.

php determines the array value Methods that are not empty

1. Use the foreach statement to traverse the array

foreach ($array as $value){
    //循环体语句块;
}

• Traverse the given $ array Array, assign the value of the current array to $value in each loop.

2. In the loop body, use the empty() function to determine whether the array element is empty

if(empty($value)){
        $i++;
    }else{
        $i=0;
        break;
}

• If If it is not empty, then $i

• If it is empty, set $i=0, and use break; to exit the entire loop.

3. Determine whether the value of $i is 0, then you can know whether there are empty elements in the array

if ($i==0) {
    echo("数组中有值为空");
} else {
    echo("数组值不为空");
}
