here is my code below,
<? foreach($goodsview as $key=>$value)
echo $value;
?>
above code works perfectly by displaying all the values in an array, now i need to fetch perticular value using foreach loop itself,
echo $value['myvalue'] ;
but iam getting an error `Illegal string offset 'myvalue' how can we fix this?
The variable $value is not an array but a string. That's the reason why the error message is being displayed.
Without seeing the code there's not much to suggest. But in general, this is how foreach loops work:
Say your array structure is as follows.
Array
(
[name] => Tom
[gender] => Male
[age] => 18
)
To display all the elements, i.e. 'Tom', 'Male', '18', you'd do something like this:
foreach ($array as $key => $value) {
echo $arr[$key].'<br>';
}
Output:
Tom
Male
18
To retrieve only a particular value:
For example, if you want to retrieve the person's name, you can do:
echo $arr['name']; //Tom
echo $arr['gender']; //Male
echo $arr['age']; //18
Hope this clears up things for you! :)
$value holds the value in your foreach loop. It's the same as $goodsview[$key]. If you just want a single value then don't use the loop. $goodsview['myvalue'] could hold a value if your Array looks like $goodsview = array('myvalue' => 'This would be the value').
This will not work, because $values does not exist
foreach($goodsview as $key => $value)
echo $values;
This might work if $value is a string or number, etc, but not if it is a array.
foreach($goodsview as $key => $value)
echo $value;
The string offset error refers to you accessing a string like an array, but the key you are using does not exist.
Let me explain.
$string = "Jake";
echo $sting[0]; //outputs 'J'
echo $sting[3]; //outputs 'e'
echo $sting['doom']; // will fail
$array = array("Jake", "doom"=>3);
echo $sting[0]; //outputs 'Jake'
echo $sting[3]; //will fail
echo $sting['doom']; // outputs 3
So $value is a string, not a array.
You can access your array like this too $goodsview[$key] which will give you the same as $value.
It may be a shot in the dark but it looks like your maybe working on something like a loop to display options for a select element. Normally you wouldn't waste time with a loop, if you were simply wanting a specific array element.
Does this give you any ideas:
<select name="myvalue">
<?php
foreach($goodsview as $key=>$value) {
$seltxt='';
// assume $myvalue is the previously posted value from the select
// if the $key matches the posted $myvalue - mark this option as selected
if (!strcmp($key,$myvalue)) $seltxt=' selected';
echo "<option value=\"$key\"$seltxt>$value</option>
";
}
?>
</select>
Just a thought.
Well Let me Answer my own question, Actually my array is a single dimentional so this method does not work
echo $value['myvalue'] ;
so we have to use
echo $arr[$key]
but it displays multiple elements as if it is running in foreachloop , so without using foreach loop we have to display the result something like
echo $goodsview['myvalue']
hope it will help someone in future if they come across with similar issue...Thank you all for responding to this question,
