How do I make var_dump apear in separate lines? - php

Question

I don't want to know about other options then var_dump, because this is for a homework assignment and my teacher wants to me to make a var_dump and then let the different object appear in separate lines, I searched a shitload of sites and I simply cant find anything pls help.
This i the code in "verzenden.php"
echo '<pre>' . var_dump($_GET) . '</pre>' . '<br>';
pre was standing in <> and "" but it wont show up in here
I tried this but it is still the same as var_dump
<form method='get' action='verzend.php'>
<label>Naam: </label><input name='naam' type='text' value=''>
<label>Klas: </label><input name='klas' type='text' value=''>
<label>Nummer: </label><input name='leerlingnummer' type='text' value=''>
<label>Vak: </label><select name='vak'>
<option value='PHP'>PHP</option>
<option value='javascript'>Javascript</option>
<option value='ASP'>ASP</option>
<option value='SQL'>SQL</option>
</select>
<label>Cijfer: </label><input name='cijfer' type='number' value='5'>
<input type='submit' value='verzend' name='verzend'>
</form>
this is what it needs to become
array(6) { ["naam"]=> string(9) "Abu Saebu"
["Klas"]=> string(5) "IO1A4"
["leerlingnummer"]=> string(8) "36353535"
["vak"]=> string(3) "PHP"
["cijfer"]=> string(1) "9"
["verzend"]=> string(7) "verzend"
}
This is what I get
array(6) { ["naam"]=> string(6) "Sjoerd" ["klas"]=> string(5) "IO1D4" ["leerlingnummer"]=> string(6) "332309" ["vak"]=> string(10) "javascript" ["cijfer"]=> string(2) "24" ["verzend"]=> string(7) "verzend" }

Do it in two line instead of a concatenate.
echo '<pre>';
var_dump($_GET);
This will give you the following:
array(6) {
["naam"]=>
string(9) "Abu Saebu"
["Klas"]=>
string(5) "I01A4"
["leerlingnummer"]=>
string(8) "36353535"
["vak"]=>
string(3) "PHP"
["cijfer"]=>
string(1) "9"
["verzend"]=>
string(7) "verzend"
}
If you don't want it to break after the =>, you could use the print_r instead:
Array
(
[naam] => Abu Saebu
[Klas] => I01A4
[leerlingnummer] => 36353535
[vak] => PHP
[cijfer] => 9
[verzend] => verzend
)
However, if you really want to use var_dump, there's a cool extension out there named xdebug that will dump the details in one line like this without the pre tag:
array (size=6)
'naam' => string 'Abu Saebu' (length=9)
'Klas' => string 'I01A4' (length=5)
'leerlingnummer' => string '36353535' (length=8)
'vak' => string 'PHP' (length=3)
'cijfer' => string '9' (length=1)
'verzend' => string 'verzend' (length=7)
