San artaigil seo, ionnsaichidh tu mar a gheibh thu an eileamaid air a chomharrachadh leis a ’phuing eagar. Bidh an dòigh làithreach a ’tilleadh luach na h-eileamaid gnàthach san raon.

Tha a phuing fhèin aig a h-uile sreath, tha sin a ’comharrachadh clàr-amais 0’th gu bunaiteach. Tha an dòigh gnàthach cuideachail ma tha thu a ’dol tarsainn air an raon agus ma dh’ fheumas tu an eileamaid puing gnàthach fhaighinn.

Dè an co-chòrdadh a th ’aig a’ ghnìomh làithreach ann am PHP?

paramadair	Fiosrachadh
sreath	An raon gus an eileamaid làithreach fhaighinn - Riatanach

Eisimpleir den ghnìomh làithreach

Eisimpleir 1. Faigh an eileamaid làithreach anns an raon a chaidh a thoirt seachad.

<?php
$members= array("Jawad", "Ahmad", "Sumerina");
echo current($members);
?>

Eisimpleir 2. San eisimpleir seo, gheibh thu a h-uile modh co-cheangailte ris an roinn modh gnàthach. Bidh na modhan sin ag obair le comharradh a-staigh nan arrays.

<?php
$members= array("Jawad", "Ahmad", "Sumerina", "ACS");

// Current element: Jawad
echo current($people) . "<br>";

// Next element of Jawad: Ahmad
echo next($people) . "<br>"; 

// Now the current element: Ahmad
echo current($people) . "<br>"; 

// Previous element of Ahmad: Jawad
echo prev($people) . "<br>"; 

// Last element: ACS
echo end($people) . "<br>"; 

// Previous element of ACS: Sumerina
echo prev($people) . "<br>"; 

// Current element: Sumerina
echo current($people) . "<br>"; 

// Move the internal pointer to the first element of the array:Jawad
echo reset($people) . "<br>"; 

// Next element of Jawad: Ahmad
echo next($people) . "<br>"; 

// Get key and value of Ahmad (current element) then moves the internal pointer forward
print_r (each($members));
?>
