To accomplish what you are trying to do, simply follow this example:
$top_h_text_**I want to use $i here!**
becomes
${"top_h_text_".$i}
So you basically take the string you want (which should be the name of an existing variable) and wrap it with ${}
CodePudding user response:
If this is in fact WordPress, and your top_h_icon_
and top_h_text
are in fact defined. This would be appropriate method for concatenation of your $i
increment and the variables. This is how you join two parts to make a single string.
Note that with WordPress and outputting dynamic variables, you should escape them.
<?php
for ( $i = 1; $i < 4; $i ) {
if ( $top_h_text_ . $i ) {
?>
<li>
<?php
if ( $top_h_icon_ . $i ) {
?>
<i ></i>
<?php
}
if ( 'fa fa-envelope' === $top_h_icon_ . $i ) {
?>
<a href="mailto:<?php echo esc_attr( $top_h_text_ . $i ); ?>"><span ><?php echo esc_attr( $top_h_text_ . $i ); ?></span></a>
<?php
} else {
?>
<span ><?php echo esc_attr( $top_h_text_ . $i ); ?></span>
<?php
}
?>
</li>
<?php
}
}
