PHP Array Replace Issue - php

Question

So recently I got stuck in some sort of array combine and replace situation.
I had this array:
array(5) {
["De"]=>
string(7) "treatee"
["Para"]=>
string(13) "Cristina Isabel Gnap"
["Principio"]=>
string(36) "Agilidade, como dinâmica de ação."
["Descricao"]=>
string(8) "sadsadsa"
}
I wanted to remove the middle name from ['Para'] field so I made a for loop like this:
for ($i = 0; $i < count($rows); $i++) {
$array = explode(' ', $rows[$i]['Para']);
$firstName = $array[0];
$lastName = $array[count($array) - 1];
$combineNames= $primeiroNome." ".$ultimoNome;
$namesCombined= str_split($combineNomes, 30);
$result = array_replace($rows[$i], $nomesArray);
}
The result of course, display this:
array(5) {
["De"]=>
string(7) "treatee"
["Para"]=>
string(20) "Cristina Isabel Gnap"
["Principio"]=>
string(36) "Agilidade, como dinâmica de ação."
["Descricao"]=>
string(8) "sadsadsa"
["0"]=>
string(13) "Cristina Gnap"
}
But what I actually need to do, is to replace the ["Para"] field with the new ["0"] field, but it seems when I put in the for something like $result = array_replace($rows[$i]['Para'], $nomesArray); it returns this:
Warning: array_replace(): Argument #1 is not an array
Can anyone help me? =D

Answer 1

To iterate over an array you can use a foreach loop. $row is prefixed with an & so that any changes you make will be applied to the original array (passing by reference).
foreach ($rows as &$row) {
$original_string = $row['Para'];
// make your changes here and assign the new value to $new_string
$row['Para'] = $new_string;
}
For reference,

Answer 2

Please use unset() function
$array = array {
["De"]=>
string(7) "treatee"
["Para"]=>
string(13) "Cristina Isabel Gnap"
["Principio"]=>
string(36) "Agilidade, como dinâmica de ação."
["Descricao"]=>
string(8) "sadsadsa"
}
unset($array['pra']);

You can use a combination of preg_split and foreach loop to achieve as shown below. By the way, you can test the result here:
<?php
$arr = [
"De" =>"treatee",
"Para" => "Cristina Isabel Gnap",
"Principio" =>"Agilidade, como dinâmica de ação.",
"Descricao" =>"sadsadsa",
];
var_dump($arr);
foreach($arr as $key=>&$value){
if($key == "Para"){
if(is_string($value)) {
$arrSplits = preg_split("#\s#", $value);
if (count($arrSplits) == 3) {
unset($arrSplits[1]);
$arr[$key] = implode(" ", $arrSplits);
}
}
}
}
var_dump($arr);
RESULT OF 1ST VAR_DUMP
array (size=4)
'De' => string 'treatee' (length=7)
'Para' => string 'Cristina Isabel Gnap' (length=20)
'Principio' => string 'Agilidade, como dinâmica de ação.' (length=42)
'Descricao' => string 'sadsadsa' (length=8)
RESULT OF 2ND VAR_DUMP
array (size=4)
'De' => string 'treatee' (length=7)
'Para' => string 'Cristina Gnap' (length=13)
'Principio' => string 'Agilidade, como dinâmica de ação.' (length=42)
'Descricao' => string 'sadsadsa' (length=8)
Alternatively, You could encapsulate the above into a Function that accepts an Array and pass-in your array like so:
<?php
function removeMiddleNamesFromArray(&$dataArray){
foreach($dataArray as $key=>&$value){
if($key == "Para"){
if(is_string($value)){
$arrSplits = preg_split("#\s#", $value);
if( count($arrSplits) == 3){
unset($arrSplits[1]);
$arr[$key] = implode(" ", $arrSplits);
}
}
}
}
return $dataArray;
}
var_dump(removeMiddleNamesFromArray($arr));
DUMPS

'De' => string 'treatee' (length=7)
'Para' => string 'Cristina Gnap' (length=13)
'Principio' => string 'Agilidade, como dinâmica de ação.' (length=42)
'Descricao' => string 'sadsadsa' (length=8)
