The HTML specification says:

Attributes are placed inside the start tag, and consist of a name and a value, separated by an "=" character. The attribute value can remain unquoted if it doesn't contain ASCII whitespace or any of " ' ` = < or >. Otherwise, it has to be quoted using either single or double quotes. The value, along with the "=" character, can be omitted altogether if the value is the empty string.

In this case, the text "abc xyz" does contain a white space and must be quoted. But it is not in your code. After PHP is done with parsing, your input tag will be:

<input type=text placeholder = name onchange= nameValidation(this) value = abc xyz disabled>

Where, "abc" will be interpreted as value and "xyz" will be interpreted an another unknown attribute.

To rectify this, you need to quote the value with \" as follows:

echo "<td> <input type=text placeholder=name onchange=nameValidation(this) value=\"" . $row["name"] . "\" disabled> </td>";

Or you can switch to single quotes:

echo '<td>';
echo '<input type="text" placeholder="Enter your name" onchange="nameValidation(this)" value="' . $row['name'] . '" disabled>';
echo '</td>';
