How do I control the selected values in select with PHP?

Like I have a select form.

Option_1Option_2 .....Option_n

The last n may be great, my design is that after the user form is submitted to MySQL, and then the user can edit it, then on the edit page, this single-selection form must appear as the value in MySQL is selected. I have read the values in MySQL is $value _select_1, how to control this select_1 form with PHP to the value of $value_select_1 to select it?

Shortly after learning PHP, I hope to advise.

Data in the database that is the data output that has been saved to take this value 1 and then the foreach output to determine whether the value is equal, equal is selected.

$value _select_1=1; $select _arr=array (' value_1 ', ' value_2 ', ' value_3 ', ' value_4 '); foreach ($select _arr as $value) {    if (Intval (substr ($value, -1,1)) = = = $value _select_1)        echo $value. ' Selected ';}

$value _select_1=1; $select _arr=array (' value_1 ', ' value_2 ', ' value_3 ', ' value_4 '); foreach ($select _arr as $value) {    if (Intval (substr ($value, -1,1)) = = = $value _select_1)        echo $value. ' Selected ';}

Thank you moderator, but why is 1 to 1?

Understand, take the last one, thank you!

 
  '; Echo '' For ($i =1; $i <=10; $i + +) {    echo 'Option_ '. $i. ';} echo '; $cur = 10;echo ';? >

Better write functions to improve code reuse

 
  '; Echo '' For ($i =1; $i <=10; $i + +) {    echo 'Option_ '. $i. ';} echo '; $cur = 10;echo ';? >

This is good, but unfortunately I have already closed the post can not give you a cent, but still expressed great thanks
