[英]PHP - Insert Value with Key from another array into Array in Specific Place
[英]Insert specific value on first $key in array
这确实使我精疲力尽:
if(isset($_POST['does_what'])){
$strings = array();
foreach($_POST['does_what'] as $key => $value){
if($value[$key] == 0){
$strings[0] = "This is $value";
}
$strings[] = $value;
}
}
这给了我错误: PHP Notice: Uninitialized string offset: 0
我试图在数组的第一个键上插入“一些额外的”文本。 并且其他键应该插入。
if(!empty($_POST['does_what']) && is_array($_POST['does_what'])){
$strings = array();
foreach($_POST['does_what'] as $key => $value){
if($value[$key] == 0){
$text = "This is ".$value
$value = array_unshift($strings[$key], $text );
}
else{
echo "Value is not a Zero";
}
$strings[] = $value;
}
}
else{
echo "Post is empty Or its not an array";
}
我想您想要更多类似这样的东西:
foreach($_POST as $key => $value){
if (count( $strings) == 0)
$strings[] = "This is $value";
else
$strings[] = $value;
