2 Obscure PHP Functions
Do note that these 2 functions below are built-in PHP functions supported in 5.3=<
GOTO
There are lots of jokes about the GOTO function in other languages, but in PHP, it can be a really useful exception catching mechanism.
<?php
restart:
if (error_condition1) {
goto error;
}
if (error_condition2) {
goto restart;
}
error:
report_error();
exit;
?>
<?php
restart:
if (error_condition1) {
goto error;
}
if (error_condition2) {
goto restart;
}
error:
report_error();
exit;
?>
<?php
restart:
if (error_condition1) {
goto error;
}
if (error_condition2) {
goto restart;
}
error:
report_error();
exit;
?> Date Parsing
12-03-11 could mean 3 different dates:
- December 3, 2011
- March 12, 2011
- March 11, 2012
It is better to be really specific when working with date and time.
<?php
$date = date_create_from_format('d-m-y', '16-03-11');
var_dump(date_format($date, 'F d, Y'));
//Outputs string(14) "March 16, 2011"
?>
<?php
$date = date_create_from_format('d-m-y', '16-03-11');
var_dump(date_format($date, 'F d, Y'));
//Outputs string(14) "March 16, 2011"
?>
<?php
$date = date_create_from_format('d-m-y', '16-03-11');
var_dump(date_format($date, 'F d, Y'));
//Outputs string(14) "March 16, 2011"
?>
