PHP date standard format

<?php
echo(strtotime("now") . "<br>");
echo(strtotime("3 October 2005") . "<br>");
echo(strtotime("+5 hours") . "<br>");
echo(strtotime("+1 week") . "<br>");
echo(strtotime("+1 week 3 days 7 hours 5 seconds") . "<br>");
echo(strtotime("next Monday") . "<br>");
echo(strtotime("last Sunday"));
?>

<?php

echo(strtotime("now") . " ");

echo(strtotime("3 October 2005") . " ");

echo(strtotime("+5 hours") . " ");

echo(strtotime("+1 week") . " ");

echo(strtotime("+1 week 3 days 7 hours 5 seconds") . " ");

echo(strtotime("next Monday") . " ");

echo(strtotime("last Sunday"));

The strtotime() function parses an English textual datetime into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 GMT). Note: If the year is specified in a two-digit format, values between 0-69 are mapped to 2000-2069 and values between 70-100 are mapped to 1970-2000. Note: Be aware of dates in […]

How to use putExtra() and getExtra() for string data

Use this to “put” the file…

Intent i = new Intent(FirstScreen.this, SecondScreen.class);   
String strName = null;
i.putExtra("STRING_I_NEED", strName);

Intent i = new Intent(FirstScreen.this, SecondScreen.class);

String strName = null;

i.putExtra("STRING_I_NEED", strName);

Then, to retrieve the value try something like:

String newString;
if (savedInstanceState == null) {
    Bundle extras = getIntent().getExtras();
    if(extras == null) {
        newString= null;
    } else {
        newString= extras.getString("STRING_I_NEED");
    }
} else {
    newString= (String) savedInstanceState.getSerializable("STRING_I_NEED");
}

String newString;

if (savedInstanceState == null) {

Bundle extras = getIntent().getExtras();

if(extras == null) {

newString= null;

} else {

newString= extras.getString("STRING_I_NEED");

}

} else {

newString= (String) savedInstanceState.getSerializable("STRING_I_NEED");

}
